X-Ray and MRI Room Cleaning — Radiation Protection 2026

Cleaning X-ray rooms and other radiological facilities involves compliance with special radiation protection procedures, gaining access to controlled zones, using appropriate cleaning agents, and close cooperation with a medical physicist. Cleaning staff must complete occupational health and safety training in ionizing radiation protection and be subject to dosimetric exposure monitoring.

For directors of diagnostic facilities and radiological department managers, these are critical questions — how can you ensure high hygiene standards without exposing cleaning staff to unnecessary radiation and without disrupting sensitive medical equipment? Reefa has been operating in the medical sector since 2020, delivering services to facilities such as Diamed Medical Center, where hygiene procedures are as important as radiation protection.

In Summary

• X-ray room cleaning requires occupational health and safety training in radiation protection and cooperation with the medical physicist responsible for the facility
• Cleaning staff enter the controlled zone only outside of patient exposure hours, typically after the room's operating hours
• The scope includes floors, examination table surfaces, lead shields, operator consoles — avoiding direct contact with X-ray tubes and apparatus heads
• Certain chemicals (especially chlorine-based) are prohibited because they can react with electronic equipment or reduce the durability of lead shields
• Dosimetric monitoring (pursuant to Article 138(1) of the Atomic Energy Act) requires that each worker performing tasks in the controlled zone be covered by individual radiation dose measurement
• Documentation includes a cleaning log, zone entry protocols, and a medical physicist's report confirming procedures comply with the radiation protection plan

How Does X-Ray Room Cleaning Differ from Standard Medical Cleaning?

X-ray, computed tomography, mammography, and magnetic resonance rooms are controlled zones within the meaning of the Atomic Energy Act and the regulation of the Minister of Health on safe conditions for using ionizing radiation for all types of medical exposure. This means that access to these rooms, length of stay, and exposure levels are subject to strict supervision.

Unlike cleaning offices, hallways, or admission wards, staff cleaning an X-ray room must obtain approval from the medical physicist to enter and complete preliminary occupational health and safety training. The training covers the basics of radiation protection, the ALARA principle (as low as reasonably achievable), zone marking, and emergency procedures. In practice, this means that not every general cleaning team can begin work in such a facility without additional qualifications.

Another difference concerns the selection of cleaning agents. Radiological equipment, especially X-ray tubes, digital detectors, and lead shields, are coated with surfaces sensitive to strong organic solvents, high-concentration alcohols, and chlorine. Medical physicists recommend pH-neutral products, free of phenol and chlorine, certified for use in medical environments. At Reefa, we use only agents with EU Ecolabel certificates or equivalents approved by the Polish Ministry of Health — this is the standard for all our contracts in medical facility cleaning in Cracow and Katowice.

Finally, cleaning time is strictly defined. Most commonly, the room is cleaned after the end of the operating day, when the apparatus is inactive, patients have left, and the key has been switched to service mode or the equipment is completely shut down. Any attempt to enter during patient exposure is unacceptable from a safety perspective and immediately increases the radiation dose to support staff.

Formal Requirements and the Role of the Medical Physicist

The Atomic Energy Act requires that each radiological facility have a medical physicist responsible for radiation protection. This person develops a radiation protection plan, which includes, among other things, a cleaning schedule and procedures. The X-ray room manager should introduce the cleaning contractor to the medical physicist before signing a cleaning contract to agree on:

• the time and frequency of cleaning staff entry,
• the scope of surfaces to be cleaned,
• a list of materials and chemicals permitted for use,
• incident reporting procedures (accidental apparatus activation, contact with exposure button).

The medical physicist issues a certificate or note in facility documentation confirming that the cleaning team has received instruction. In practice, Reefa participates in such introductory meetings at each new radiological facility — this is part of our standard dedicated facility coordinator, who is responsible for procedure continuity.

Additionally, the act requires that each worker exposed to ionizing radiation as part of their work be covered by dosimetric monitoring. For cleaning staff who enter the controlled zone incidentally, a passive dosimeter is typically sufficient — a small film or thermoluminescent detector worn on the chest for a period of one month or quarter. Dosimeters are sent to an accredited laboratory after the measurement period, which issues a report. If the accumulated dose exceeds the alarm threshold (in practice, 1 mSv per quarter), the medical physicist implements corrective measures — for example, shortening the time spent in the area or conducting additional training.

Frequency and Detailed Scope of X-Ray Room Cleaning

The recommended frequency for an X-ray room performing up to 30 examinations daily is daily cleaning after the end of the operating day, or possibly two interventions (one midday, one in the evening) if the room operates on a two-shift schedule. For mammography facilities with lower patient volume, daily evening cleaning is sufficient, while for interventional radiology or computed tomography operating 24/7, time windows between patient sessions must be adjusted accordingly.

The scope of work includes:

1. Floors — vacuuming or dry mopping with an antistatic mop, followed by wet cleaning with a pH-neutral agent. Water spills near the apparatus power cables must be avoided.
2. Examination tables — disinfection of the surface on which the patient lies, using an alcohol solution up to 70% concentration or a quaternary ammonium compound. Spraying side shields and electronic covers must be avoided.
3. Lead shields (aprons, screens) — wiping with a damp microfiber cloth without chlorine. Lead shields crack over time if cleaned with aggressive chemicals.
4. Operator console — disinfection of the keyboard, mouse, and touch monitor. Particular caution here: never spray the agent directly on electronic equipment, only on the cloth.
5. Walls and doors — in X-ray rooms, walls are typically finished with drywall-lead panels or lead-lined cladding, painted with latex paint. They can be washed with pH-neutral soap and water, avoiding spraying lead door frames.
6. X-ray tube, head, and C-arm — these components are cleaned only by technical service or a radiological nurse with appropriate qualifications. Cleaning staff do not touch the X-ray tube head directly.
7. Portable apparatus — if the room has a mobile X-ray apparatus on wheels, the housing and wheels are wiped with a damp cloth after each use.

The order of cleaning is particularly important: surfaces and furniture first, followed by floors, to avoid spreading dirt. In magnetic resonance rooms, remember that the strong magnetic field attracts metal objects — cleaning trolleys, steel buckets, and metal ladders are prohibited. Only plastic or aluminum equipment is used.

Which Chemicals Are Prohibited in an X-Ray Room?

Medical physicists and radiological equipment manufacturers list several substances that can damage equipment or protective coatings:

• Chlorine and sodium hypochlorite at high concentrations (above 0.5%) — corrodes lead shields and damages electronics.
• Phenol — a strong disinfectant, but leaves residue on digital detectors.
• Aldehydes (glutaraldehyde, formaldehyde) — used in high-level disinfection, but their presence in X-ray rooms is not necessary and may threaten staff.
• Organic solvents (acetone, benzene, toluene) — damage polymer coatings, silicone seals, and power cables.
• Alcohol above 70% concentration — can dry out and crack rubber seals.

Instead, Reefa uses agents registered as medical biocidal products with antibacterial, antifungal, and antiviral spectra (effective against enveloped viruses, including SARS-CoV-2), with a pH of 5.5–7.5, without chlorine or phenol. Example products include solutions of quaternary ammonium compounds or preparations based on hydrogen peroxide at low concentration. Each product is consulted with the medical physicist before first use.

Exposure Monitoring and Work Documentation

Under the Polish Atomic Energy Act (Journal of Laws 2022, item 1375, as amended), workers exposed to ionizing radiation are subject to individual monitoring. For cleaning workers entering the controlled zone incidentally (several minutes daily, outside active exposure time), passive dosimeters are typically used — TLD (thermoluminescent) or OSL (optically stimulated luminescence) devices.

The employer — in this case, the cleaning company — is obligated to:

1. Provide a personal dosimeter to each worker entering the controlled zone.
2. Maintain a book of individual radiation doses, which during a National Atomic Energy Agency inspection serves as the primary document.
3. Organize medical examinations related to ionizing radiation exposure (initial examination, periodic examination every 12 months, control examination before the end of work in hazardous conditions).
4. Provide access to medical and dosimetric documentation for 50 years after the end of work in hazardous conditions.

In practice, Reefa cooperates with a selected dosimetric laboratory that provides dosimeters for our workers servicing radiological facilities. Monthly reports are received by the facility coordinator, and an annual summary is provided to both the National Atomic Energy Agency and the facility's medical physicist. This gives both the client and the contractor full transparency and proof that protective procedures are being followed.

In addition to dosimetric monitoring, work documentation is important. After each cleaning, the room receives an entry in the cleaning log with the date, time, name of the person cleaning, and description of work performed. At Reefa, we additionally provide photo reports after each cleaning — images selected by the coordinator documenting the condition of the rooms, along with a QR code for reporting comments. This is particularly valued in medical facilities subject to external audits, such as ISO 9001 certification or accreditation by the Center for Monitoring Quality in Healthcare.

Cooperation with the Radiological Team

Cleaning an X-ray room is not only a technical matter but also an organizational one. In practice, successful service requires close communication between the room manager, medical physicist, coordinating nurse, and cleaning company. At the beginning of cooperation, it is worthwhile to establish:

• Access hours — typically cleaning takes place after 6:00 PM or before 7:00 AM, when equipment is off or locked.
• Storage location for materials and equipment — cleaning trolleys cannot remain in the exposure room; they are typically stored in an auxiliary room at the room's exit.
• Alarm procedure — what to do in case of accidental contact with the exposure button, equipment malfunction, chemical spill, or worker injury. Each cleaning team member should know the medical physicist's phone number and the facility's occupational health and safety service.
• Training schedule — initial training typically lasts about 2 hours, with annual refresher training of 30 minutes. Some facilities organize joint training with emergency medical services and GDPR principles.

In our service model, each medical facility — including X-ray rooms — has a dedicated coordinator, who is the single point of contact for the room manager. This person participates in instruction from the medical physicist, provides feedback to the cleaning team, and responds to complaints through the QR system within 24 hours.

It is worth emphasizing that smooth cooperation directly translates to risk levels: procedural errors in an X-ray room can lead not only to radiation exposure but also to damage to expensive equipment worth millions of zlotys. Therefore, directors of diagnostic facilities increasingly choose specialized companies that have legally employed and insured staff, professional liability insurance up to 500,000 PLN (this is what our coverage has been since 2020), and documented experience in sanitizing medical facilities.

Occupational Health and Safety Training in Radiation Protection — What Must the Cleaning Team Know?

A training program for cleaning staff developed jointly with the medical physicist should cover at least five subject areas:

1. Basics of ionizing radiation — what X-radiation is, how an X-ray apparatus works, why it is forbidden to stay in the room during exposure.
2. The ALARA principle — minimizing time spent in the area, maximizing distance from the source, using shields (for cleaning purposes, there is practically no need for additional shields since the apparatus is off).
3. Zone marking — radiation trefoil, warning signs, light signaling on room doors.
4. Emergency procedures — what to do if the light above the door begins to glow red during cleaning (immediately exit, close the door, notify the on-call radiologist or medical physicist).
5. Dosimetry and documentation — how to wear a dosimeter (on the chest, always facing forward), how to fill in entry and exit logs, where to check accumulated dose.

Training is completed with a short test or summary discussion. The medical physicist issues a training completion certificate, which is placed in the worker's personnel file and shown during National Atomic Energy Agency inspections. The cost of such training typically ranges from 100 to 300 PLN net per person, depending on scope and location. At Reefa, we cover these costs as part of our standard offering for medical facilities — it does not impose additional expenses on the client.

It is worth remembering that occupational health and safety training in radiation protection is not a one-time requirement. Regulations require knowledge refreshing at least once a year, especially if the facility has modernized equipment or changed its radiation protection plan. In practice, for the purposes of audits and certifications, many medical facilities organize joint occupational health and safety training with HACCP, GDPR, and radiation protection elements — such a synergistic formula saves time and raises the overall level of team awareness.

How Much Does Professional X-Ray Room Cleaning Cost?

The price of radiological facility cleaning depends on several factors:

• Room area — a typical X-ray room with one workstation is 20–30 m², a computed tomography room 25–40 m², a magnetic resonance room 40–60 m² (larger due to the shielded chamber).
• Frequency — daily service costs more per month than service 3× per week.
• Additional scope — waiting area, control room (console), entrance corridor, patient restroom.
• Documentation requirements — photo reports, dosimetric monitoring, professional liability insurance, coordinator availability in express mode.

In the Reefa model for an X-ray room of 25 m² with service 6 days a week, the rate is in the range of 18–24 PLN net per square meter per month. For larger diagnostic facilities (e.g., an imaging center with several X-ray, CT, and MR rooms), we offer a comprehensive model with one coordinator for the entire facility, which reduces the unit rate to 15–20 PLN net/m²/month.

Additional costs may include:

• Training and dosimetric monitoring — from 50 PLN net per month per worker (dosimeter cost, laboratory service, dose record updates).
• Specialist pH-neutral agents with EU Ecolabel certificate — usually included in the price, but some high-end products may increase costs by 5–10%.
• Express intervention (e.g., after contrast spill, biohazard contamination) — from 150 PLN net per callout within 2 hours.

For comparison, standard medical office cleaning without radiological exposure costs around 10–14 PLN net/m²/month, confirming that radiological specialization increases rates by approximately 50–80% due to the requirements of formal training, monitoring, and documentation.

X-Ray Room Requirements — Legal Context

The establishment and operation of a radiological facility in Poland are regulated by:

• The Act of November 29, 2000, the Atomic Energy Act (Journal of Laws 2022, item 1375, as amended),
• Regulation of the Minister of Health of February 18, 2011, on safe conditions for using ionizing radiation for all types of medical exposure (Journal of Laws 2011 No. 51, item 265, as amended),
• Regulation of the Council of Ministers of January 18, 2005, on dose limits for ionizing radiation (Journal of Laws 2005 No. 20, item 168).

Key requirements include:

1. X-ray room walls must be made of material with an equivalent lead thickness of at least 2 mm (for general apparatus up to 125 kV) or have another form of radiation-absorbing shielding.
2. Entry doors must be equipped with light signaling (e.g., a red light illuminates during exposure) and a lock preventing opening from outside during irradiation.
3. The control room (operator console) must be separated from the exposure room by a protective wall with a lead window or a separate compartment.
4. The facility must have a radiation protection plan approved by the President of the National Atomic Energy Agency.
5. Exposed personnel — including incidental support staff — are subject to occupational health and safety training and dosimetric monitoring.

For cleaning companies, it is important to note that legal responsibility for compliance with these requirements rests with the facility owner (medical facility, hospital, diagnostic clinic), but the service contractor is liable for damages resulting from procedural errors (e.g., accidental cable damage, spilling aggressive chemicals on lead shielding). Therefore, having professional liability insurance of at least 500,000 PLN is a de facto requirement in most medical contracts.

Magnetic Resonance Room Cleaning — Additional Considerations

Magnetic resonance (MRI) does not emit ionizing radiation but generates a strong magnetic field (typically 1.5 or 3 Tesla). This presents completely different challenges for the cleaning team:

• Prohibition of ferromagnetic objects — steel buckets, trolleys with metal frames, keys, scissors, mobile phones can be violently attracted by the magnet and damage the apparatus or injure people in the room. Only equipment made of plastic, aluminum, or composite materials marked as "MR-safe" is used.
• No radiological dosimetry, but entry to the MR zone requires occupational health and safety training in magnetic field safety, which is the responsibility of the medical physicist or MR coordinator.
• Shielded room — the MR facility room is surrounded by a Faraday cage made of copper or stainless steel that blocks radio waves. Care must be taken not to scratch or damage the shielding panels during cleaning.
• Liquid helium — older MR apparatus use liquid helium to cool superconductors. A leak can lead to helium evaporation and oxygen displacement from the room (so-called quench). Cleaning staff must know the location of low-oxygen alarms and evacuation procedures.

In practice, Reefa inspects equipment (trolleys, mops, buckets) by the medical physicist or their substitute before starting to work in an MR facility, to confirm the absence of ferromagnetic elements. A set of equipment dedicated solely to the MR room remains on site and is not used in other areas.

Frequently Asked Questions

What are the requirements for an X-ray facility?

An X-ray room must comply with the requirements of the Atomic Energy Act and regulations of the Minister of Health: walls with an equivalent lead thickness of at least 2 mm, doors with light signaling and a lock, a separate operator console behind shielding, an approved radiation protection plan, and employment of a medical physicist. The room is marked as a controlled zone, meaning limited access and dosimetric monitoring of people entering. Additionally, the facility requires permission from the President of the National Atomic Energy Agency to conduct activities related to ionizing radiation exposure and regular technical and dosimetric inspections of equipment by authorized entities. In the context of cleaning, the most important thing is to follow the access schedule outside of patient exposure hours and use cleaning agents approved by the medical physicist.

Does X-ray radiation penetrate walls?

X-ray radiation can penetrate building walls, which is why X-ray rooms are designed with radiation-absorbing shields. The most popular material is lead, but barite concrete with increased density is also used to block X-ray photons. The shield thickness is determined by calculations of the medical physicist, taking into account apparatus power, distance from the wall, type of room on the other side (e.g., corridor, office, public space), and permissible doses for people in the vicinity. In practice, X-ray room walls are made of drywall-lead panels approximately 2–3 mm lead-equivalent thick, which reduces the external dose to below the limit for the general population (1 mSv/year). For cleaning staff entering the exposure room after exposure is complete, the risk related to radiation penetrating walls is practically zero, since the apparatus only generates radiation at the moment of exposure.

Who can perform X-rays?

X-ray examinations are performed by a radiologist with a specialization in radiology and diagnostic imaging or a physician in training under supervision. The apparatus is directly controlled by an electro-radiology technician — a medical profession requiring at least secondary medical education and qualifications in electro-radiology or interventional radiology. The Atomic Energy Act requires that the person operating the X-ray apparatus complete training in radiation protection and be under the supervision of a medical physicist. Cleaning staff do not perform examinations or operate the apparatus but may be in the room only outside of patient exposure time. Any attempt to operate the apparatus by a person without authorization is a violation of regulations and can result in administrative penalties and fines.

How often should an X-ray room be cleaned?

The frequency of X-ray room cleaning depends on patient volume and recommendations from the medical physicist. In most cases, a daily cleaning model is used after the end of the operating day — typically in the evening after 6:00 PM or in the morning before 7:00 AM. Facilities performing over 50 examinations per day (e.g., computed tomography in a multi-specialty hospital) may require mid-shift cleaning between sessions. On weekends and holidays, if the room is not operating, weekly maintenance cleaning is sufficient. The scope includes floor washing, disinfection of the examination table, operator console, lead shields, and touch surfaces. Additional cleaning after each patient — at least disinfection of the table surface — is typically performed by the electro-radiology technician or nurse, not by an external cleaning team.

Does magnetic resonance room cleaning require the same procedures as X-ray?

Magnetic resonance room cleaning does not require ionizing radiation dosimetric monitoring since MRI does not emit X-rays — it operates on the basis of magnetic field and radio waves. The key is, however, occupational health and safety training in magnetic safety: prohibition on introducing ferromagnetic objects (steel buckets, trolleys, keys, mobile phones can be violently attracted by the magnet), using equipment marked as "MR-safe," and knowing the emergency procedure in case of quench (sudden liquid helium evaporation and oxygen displacement from the room). The medical physicist responsible for the MR facility must approve the list of cleaning equipment before first entry to the magnet zone. Cleaning frequency is similar to X-ray rooms — daily after the end of the operating day, except there are no time restrictions related to ionizing radiation exposure since the magnetic field operates continuously.

What does dosimetric monitoring of workers in X-ray rooms look like?

Each worker entering the controlled zone (including cleaning staff) must be covered by individual dosimetric monitoring. In practice, a passive dosimeter is provided (typically thermoluminescent TLD or optically stimulated OSL), worn on the chest for a period of one month or quarter. After the measurement period, the dosimeter is sent to an accredited dosimetric laboratory, which issues a report with the recorded accumulated radiation dose. Results are entered in the individual dose record kept by the employer (cleaning company) and provided to the facility's medical physicist. If the dose exceeds the alarm threshold (typically 1 mSv per quarter), the medical physicist implements corrective measures — for example, shortening time spent in the controlled zone or conducting additional training. All dosimetric documentation must be retained for 50 years after the end of work in hazardous conditions, in accordance with the Atomic Energy Act.
