X-ray and radiation safety for nurses is an important part of maintaining a safe healthcare environment. Nurses may work around diagnostic imaging equipment in emergency departments, operating rooms, intensive care units, radiology departments, and other clinical settings where patients receive X-rays or other radiation-based procedures.
Medical imaging can provide valuable information for diagnosing and treating patients. However, ionizing radiation can cause biological effects when exposure is excessive or repeated unnecessarily. Nurses therefore need to understand basic radiation safety principles and follow established workplace procedures.
Radiation safety does not mean avoiding every X-ray procedure. Instead, it involves reducing unnecessary exposure while ensuring patients receive appropriate medical care.
The following six safety tips can help nurses understand basic radiation protection practices and reduce occupational exposure.

What Is Radiation Safety in Nursing?
Radiation safety refers to practices designed to protect patients, healthcare professionals, visitors, and other individuals from unnecessary exposure to ionizing radiation.
Understanding Ionizing Radiation
X-rays are a form of ionizing radiation. Unlike non-ionizing radiation, ionizing radiation has enough energy to remove electrons from atoms and can cause biological changes in living tissue.
Medical X-rays are carefully controlled and are commonly used for diagnosis and certain procedures. Radiation protection practices help keep exposure as low as reasonably achievable while still obtaining the necessary clinical information.
Why Nurses Need Radiation Safety Knowledge
Nurses may not operate X-ray equipment themselves, but they may be present when imaging procedures are performed.
For example, nurses may assist with patient positioning, monitor patients during procedures, provide medications, support emergency care, or remain nearby when portable X-rays are performed.
Understanding radiation safety helps nurses recognize situations where additional protection or distance is appropriate.
The ALARA Principle
One of the most important concepts in radiation protection is the ALARA principle.
What Does ALARA Mean?
ALARA stands for As Low As Reasonably Achievable. The principle means radiation exposure should be minimized while still allowing the necessary medical procedure to be completed effectively.
ALARA is based on three fundamental approaches:
- Reduce the time spent near the radiation source.
- Increase distance from the radiation source.
- Use appropriate shielding.
These principles are relevant to nurses who may work around diagnostic X-ray equipment or fluoroscopy procedures.
6 X-Ray and Radiation Safety Tips for Nurses
Nurses can use several practical strategies to reduce unnecessary occupational exposure. These six tips focus on the most important principles of radiation protection.
Minimize Time Near Radiation Sources
The first radiation safety tip is to reduce the amount of time spent near an active radiation source.
Why Time Matters
Radiation exposure generally increases with the amount of time a person spends near a radiation source. Spending less time in an area where radiation is being produced can therefore help reduce occupational exposure.
Nurses should avoid remaining in a radiation area when their presence is not clinically necessary.
Plan Before the Procedure
Preparation can help reduce unnecessary time near radiation-producing equipment.
Before an imaging procedure, nurses should understand their responsibilities and gather necessary equipment or supplies when appropriate. Completing these tasks before exposure begins can reduce unnecessary time near the patient and radiation source.
Leave When Your Presence Is Not Required
If a nurse does not need to remain in the room during an X-ray exposure, leaving the area can be an effective way to reduce exposure.
However, patient safety remains the priority. Nurses should follow facility policies and remain available when their clinical responsibilities require them to do so.Maximize Distance From the Radiation Source
Distance is another important radiation protection principle.
Why Distance Is Important
Radiation intensity decreases significantly as distance from the radiation source increases. Therefore, moving farther away from an X-ray source when practical can reduce exposure.
Even a relatively small increase in distance can make a meaningful difference during certain procedures.
Step Away When Possible
When a portable X-ray is being performed, nurses should move away from the patient and equipment when they are not required to provide direct care.
If remaining nearby is necessary, positioning should follow facility radiation safety procedures and guidance from qualified imaging professionals.
Avoid Standing Close to the Tube
Nurses should avoid standing unnecessarily close to the X-ray tube or other radiation sources.
The appropriate position depends on the specific procedure and equipment, so nurses should follow instructions from radiology personnel and their organization’s radiation safety program.
Use Appropriate Radiation Shielding
Shielding can provide additional protection when personnel need to remain near radiation-producing equipment.
Lead Aprons
Lead or lead-equivalent protective aprons may be used during certain procedures when staff must remain in an area where radiation exposure can occur.
Protective equipment should be appropriate for the procedure and used according to facility policy.
Thyroid Protection
The thyroid is sensitive to ionizing radiation. Depending on the procedure and workplace requirements, thyroid protection may be recommended for personnel who need to remain near radiation sources.
Protective Barriers
Fixed or mobile protective barriers can provide additional shielding during some imaging procedures.
When available, nurses should use designated protective barriers rather than relying solely on personal protective equipment.
Inspect Protective Equipment
Protective equipment should be stored, handled, and inspected according to manufacturer and facility instructions.
Damaged protective equipment may not provide the intended protection and should be reported appropriately.
Wear and Use Radiation Monitoring Devices Correctly
Some healthcare professionals who work in environments with occupational radiation exposure may be required to use personal dosimeters.
What Is a Dosimeter?
A dosimeter is a device used to monitor an individual’s occupational radiation exposure.
Depending on the work environment and radiation safety program, personnel may use different types of monitoring devices.
Wear Dosimeters Correctly
Nurses who are issued radiation monitoring devices should follow their facility’s instructions regarding placement, use, storage, and handling.
A dosimeter should not be shared between employees because it is intended to record the exposure associated with the individual wearing it.
Review Exposure Reports
Radiation monitoring programs may periodically review exposure records.
If an unusual or unexpectedly high reading occurs, the appropriate radiation safety personnel should investigate the situation according to established procedures.
Follow Radiation Safety Procedures During Portable X-Rays
Portable X-rays are commonly used when patients cannot easily be transported to an imaging department.
Why Portable Imaging Requires Attention
Portable X-ray equipment may be used in emergency departments, intensive care units, inpatient rooms, operating areas, and other clinical environments.
Because the equipment is brought directly to the patient, nurses may be nearby during the procedure.
Clear the Area When Possible
When a portable X-ray is scheduled, unnecessary personnel should leave the immediate area when practical.
Other patients, visitors, and staff should also be moved away from the radiation area when appropriate.
Communicate With the Imaging Team
Nurses should communicate with radiologic technologists and other imaging professionals before the exposure.
The imaging professional can provide instructions about where staff should stand and whether they need to leave the area.
Following these instructions can help reduce unnecessary occupational exposure while maintaining patient safety.
Understand Special Precautions for Pregnancy
Pregnancy can raise additional questions about occupational radiation exposure.
Inform the Appropriate Workplace Professional
Nurses who are pregnant or believe they may be pregnant should understand their employer’s occupational radiation policies and applicable workplace procedures.
Depending on the workplace and role, an employee may choose to confidentially notify the appropriate occupational health, radiation safety, or supervisory professional to discuss exposure precautions.
Continue Appropriate Patient Care
Pregnancy does not necessarily mean that a nurse cannot work in an environment where X-rays are performed. Appropriate radiation protection practices can help manage occupational exposure.
Specific recommendations should be based on the individual’s workplace, duties, exposure levels, and applicable professional guidance.
Radiation Safety in the Operating Room
Radiation safety is particularly important in operating rooms where fluoroscopy or other imaging systems may be used during procedures.
Follow the Procedure-Specific Safety Plan
Operating room staff should understand when radiation-producing equipment will be activated and where personnel should stand.
Nurses should follow instructions from radiology or surgical imaging professionals and use appropriate protective equipment when required.
Use Distance and Shielding
When practical, staff should maximize their distance from the radiation source and use available protective barriers or appropriate protective clothing.
Nurses should avoid standing directly beside the radiation source unless their clinical role requires them to be there.
Radiation Safety During Fluoroscopy
Fluoroscopy uses X-rays to create real-time images and is used in several medical procedures.
Why Fluoroscopy Requires Attention
Some fluoroscopic procedures can involve longer radiation exposure than a single diagnostic X-ray. Nurses who frequently work around fluoroscopy should therefore understand their facility’s radiation protection practices.
Limit Unnecessary Exposure
The same basic principles apply: minimize time, maximize distance, and use appropriate shielding.
Staff should avoid remaining close to the radiation source when their presence is not necessary for patient care.
Patient Radiation Safety
Radiation safety is not only about protecting nurses. Nurses also have an important role in supporting patient safety.
Verify the Correct Patient and Procedure
Before imaging, nurses should follow appropriate patient identification and procedural verification practices.
Correct identification helps prevent unnecessary imaging and ensures that the intended patient receives the appropriate examination.
Communicate Relevant Information
Nurses may need to communicate relevant clinical information to the imaging team, including patient mobility limitations, pregnancy-related information when appropriately disclosed, allergies or medications relevant to the procedure, and other clinical concerns.
The specific information required depends on the imaging procedure.
Common Radiation Safety Mistakes Nurses Should Avoid
Understanding common radiation safety mistakes can help nurses reduce unnecessary occupational exposure and maintain a safer clinical environment. Nurses may encounter X-rays and other radiation-producing equipment in emergency departments, operating rooms, intensive care units, radiology areas, and during portable imaging procedures. Following established safety procedures is important whenever radiation is being used.
Standing Nearby Without a Clinical Reason
One common mistake is remaining close to an active X-ray source when the nurse’s clinical responsibilities do not require it. Unnecessary time near a radiation source can increase occupational exposure.
When direct patient care is not required, nurses should leave the immediate area or move to an appropriate protected location. If remaining with the patient is necessary, the nurse should follow the imaging team’s instructions regarding positioning and protective measures.
Ignoring Protective Barriers
Protective barriers are an important part of radiation protection when they are available and appropriate for the procedure. Nurses should use designated barriers according to facility policies rather than standing unnecessarily close to the radiation source.
Mobile barriers, fixed shields, and other protective structures may provide additional protection during certain procedures. Staff should understand where these barriers are located and how they should be used.
Misusing Protective Equipment
Protective aprons, thyroid shields, and other radiation protection equipment should be used correctly and handled carefully. Improper folding, storage, or handling can potentially damage protective materials.
Nurses should follow manufacturer and facility instructions for inspecting, storing, and maintaining protective equipment. Any suspected damage should be reported according to workplace procedures.
Forgetting Radiation Monitoring Requirements
Some nurses who regularly work around radiation-producing equipment may be required to wear a personal dosimeter. Forgetting to wear the device or using it incorrectly can interfere with accurate monitoring of occupational exposure.
Nurses who are issued dosimeters should follow their radiation safety program’s instructions regarding placement, use, storage, and reporting.
Radiation Safety Training for Nurses
Training can help nurses understand how to work safely around medical imaging equipment.
Orientation Training
New employees who may encounter radiation-producing equipment should receive appropriate workplace orientation.
Training may cover radiation basics, protective equipment, monitoring devices, emergency procedures, and facility-specific requirements.
Continuing Education
Periodic education can reinforce radiation safety principles and introduce updates to workplace procedures.
Nurses who regularly work with fluoroscopy or other radiation-producing equipment may need additional training based on their roles.
Why Communication Matters in Radiation Safety
Effective communication can reduce confusion during imaging procedures.
Communicate Before Exposure
Nurses should know when radiation exposure is about to occur whenever their clinical role requires them to remain nearby.
Radiologic technologists can provide important instructions about positioning, shielding, and when staff should leave the room.
Coordinate Patient Care
Patient monitoring remains important during imaging procedures. Nurses should coordinate with the imaging team so that radiation protection does not interfere with essential patient care.
Are nurses exposed to radiation during X-rays?
Nurses may receive occupational exposure if they remain near radiation-producing equipment during procedures. Exposure can be minimized by following radiation protection principles such as reducing time, increasing distance, and using appropriate shielding.
Should nurses wear lead aprons during X-rays?
Whether protective aprons are required depends on the procedure, workplace policies, radiation levels, and whether the nurse must remain in the area during exposure. Nurses should follow facility-specific radiation safety guidance.
What does ALARA mean in radiation safety?
ALARA means As Low As Reasonably Achievable. It is a radiation protection principle focused on minimizing unnecessary exposure while still allowing the required medical procedure to be performed.
Can pregnant nurses work around X-rays?
Pregnant nurses may be able to work safely around medical imaging when appropriate radiation protection practices are followed. Nurses should discuss occupational exposure with the appropriate workplace radiation safety or occupational health professional to understand applicable precautions.
What are the three basic principles of radiation protection?
The three commonly taught principles are time, distance, and shielding. Reducing exposure time, increasing distance from the radiation source, and using appropriate shielding can help reduce occupational exposure.
