Radiation safety is an essential part of operating X-ray equipment in medical and veterinary environments. While diagnostic X-rays are valuable tools for producing medical images, staff and other individuals in the X-ray room should follow established procedures to minimize unnecessary radiation exposure.
Protective equipment such as lead aprons, protective gloves, mittens or gauntlets, thyroid shields, and protective barriers can be an important part of an overall radiation-safety program.
For veterinary practices, this is particularly important because staff may sometimes need to remain near an animal during positioning or imaging. Health Canada's Safety Code 28 provides specific recommendations for radiation protection when veterinary X-ray equipment is used.
What Is Radiation Safety?
Radiation safety refers to the practices, equipment, procedures, and controls used to reduce unnecessary exposure to ionizing radiation.
In an X-ray environment, radiation safety involves much more than simply wearing protective clothing. A comprehensive approach can include:
Proper X-ray room design
Appropriate shielding
Safe equipment operation
Correct patient positioning
Distance from the X-ray source
Minimizing exposure time
Appropriate beam collimation
Protective barriers
Personal protective equipment
Personal dosimeters
Equipment maintenance
Radiation surveys
Staff training
The goal is to obtain the required diagnostic images while keeping unnecessary exposure as low as reasonably achievable.
Why Is Radiation Safety Important in X-Ray Imaging?
X-rays are a form of ionizing radiation. Repeated or unnecessary exposure should therefore be minimized.
Health Canada's veterinary radiation-safety guidance states that personnel working with or around veterinary X-ray equipment should be protected from excessive exposure and recommends measures such as shielding, distance, protective clothing, and safe operating procedures.
In medical radiography, Health Canada's current Safety Code 35 similarly emphasizes protective equipment, shielding, dosimetry, and safe operating practices.
A good radiation-safety program combines engineering controls, administrative procedures, safe working practices, and personal protective equipment.
What Is a Lead Apron?
A lead apron is a protective garment designed to reduce exposure to scattered X-ray radiation reaching the wearer's torso.
Lead aprons are commonly used when personnel must remain in or near the X-ray room during an examination.
Depending on the application, protective aprons may be available in different designs, sizes, materials, and lead-equivalent ratings.
Lead apron selection should be based on:
Intended application
X-ray equipment
Operating environment
Required lead equivalence
Coverage
Fit
Weight
Comfort
Manufacturer specifications
Applicable regulatory requirements
Health Canada's medical X-ray Safety Code 35 specifies minimum lead-equivalent values for protective aprons based on the X-ray tube voltage and recommends that protective equipment be tested for integrity annually.
Lead Aprons for Veterinary X-Ray
Veterinary radiography can present unique radiation-safety challenges because animals may require positioning or restraint.
Whenever possible, appropriate positioning devices, sedation, or other methods should be considered to reduce the need for personnel to remain close to the X-ray beam.
When a person must assist with restraint, protective clothing and other safety measures become particularly important.
Health Canada's Safety Code 28 recommends protective aprons, gloves, and thyroid shields for veterinary X-ray applications and states that personnel should avoid exposure to the primary X-ray beam.
Lead Aprons vs. Lead Aprons With Thyroid Protection
Some protective garments are designed to be used with a separate thyroid shield, while others may be available as integrated or coordinated protection systems.
The thyroid is particularly sensitive to radiation, so thyroid protection may be appropriate in situations where personnel are exposed to scattered radiation.
When selecting protective clothing, consider whether the practice requires:
Standard apron protection
Wrap-around protection
Front protection
Separate thyroid collar
Integrated thyroid protection
Additional protective accessories
The appropriate configuration depends on the X-ray application and applicable safety requirements.
What Are Lead Gloves?
Protective X-ray gloves are designed to reduce radiation exposure to the hands when personnel must work near an active X-ray examination.
They can provide protection for the hands, fingers, and wrists when properly designed and used.
However, protective gloves should never be considered permission to place the hands in the primary X-ray beam.
Health Canada's veterinary guidance specifically states that personnel should avoid exposure to the X-ray beam and that, when animal restraint is necessary, protective clothing should be worn while direct exposure to the beam is avoided.
Lead Gloves and Veterinary Radiography
Veterinary radiography can sometimes require personnel to assist with animal positioning.
For example, a nervous, injured, or uncooperative animal may require additional assistance to remain properly positioned.
Radiation safety should always come first.
Whenever practical, veterinary practices should consider:
Appropriate restraint devices
Positioning aids
Sedation when clinically appropriate
Increasing distance from the X-ray source
Protective barriers
Proper collimation
Minimizing exposure time
Protective aprons
Protective gloves
Thyroid protection
Personal dosimetry
Personnel who routinely participate in radiographic procedures should follow the radiation-safety program established for the facility.
What Are Lead Mittens or Gauntlets?
Lead mittens and gauntlets are protective hand and arm equipment designed for applications where additional coverage is required.
They can be useful when personnel need protection extending beyond the hands and wrists.
The terminology can vary between manufacturers. Products may be described as:
Lead gloves
Protective gloves
Radiation gloves
Lead mittens
Protective mittens
Lead gauntlets
Radiation-protective gauntlets
When comparing products, look beyond the product name and review the manufacturer's specifications, coverage, lead equivalence, intended application, and applicable standards.
Thyroid Shields
The thyroid gland can be exposed to scattered radiation during some X-ray procedures.
A thyroid shield is designed to provide additional protection around the neck.
Thyroid protection can be particularly useful when personnel must remain close to the patient during procedures where scatter radiation is present.
Health Canada's veterinary guidance includes thyroid shields among the protective clothing used for veterinary X-ray examinations.
Lead Glasses and Eye Protection
The eyes can also be exposed to scattered radiation.
For procedures involving increased exposure to scatter, appropriate radiation-protective eyewear may be considered.
Health Canada's Safety Code 35 recommends protective glasses for certain higher-exposure procedures such as interventional work and specifies a lead-equivalent value for that application.
The appropriate eye protection depends on the procedure, equipment, exposure conditions, and applicable requirements.
Mobile Radiation Protection Barriers
Personal protective clothing is only one part of radiation safety.
A mobile protective barrier can provide additional shielding between personnel and the source of scattered radiation.
Depending on the application, facilities may use:
Mobile lead barriers
Lead-acrylic viewing screens
Fixed protective barriers
Ceiling-suspended shields
Table-mounted protective shields
Health Canada's Safety Code 35 includes protective screens and mobile shields among the equipment used for radiation protection and specifies lead-equivalent requirements for certain protective barriers.
The Importance of Distance
Distance is one of the fundamental principles of radiation safety.
When practical, personnel should maximize their distance from the X-ray source and patient during exposure.
Health Canada's veterinary guidance recommends that personnel remain as far away from the X-ray beam as practicable and avoid exposure to the primary beam.
This is especially important in veterinary radiography, where personnel may be tempted to remain close to an animal during an exposure.
Minimize Exposure Time
Reducing unnecessary time near an active X-ray source is another important radiation-safety practice.
A well-organized imaging workflow can help reduce unnecessary exposure by:
Preparing equipment before exposure
Positioning the patient correctly
Using appropriate exposure settings
Communicating clearly with staff
Limiting the number of repeat exposures
Leaving the room or moving behind a barrier when appropriate
The objective is not simply to perform the examination quickly, but to perform it safely and efficiently while obtaining the required diagnostic image.
Proper X-Ray Beam Positioning
The primary X-ray beam should be directed toward an appropriately shielded or unoccupied area.
Health Canada's veterinary Safety Code 28 states that the radiation beam should be directed toward adequately shielded or unoccupied areas and that shielding should be used to reduce radiation levels.
Proper beam positioning and collimation can therefore be important components of an effective radiation-safety program.
Personal Dosimeters
A personal dosimeter is a device used to monitor an individual's exposure to ionizing radiation over a specified period.
Dosimeters can help a facility monitor occupational exposure and identify potential problems with equipment, workload, or operating procedures.
Health Canada recommends dosimetry for personnel who routinely participate in radiological procedures or who may receive specified levels of occupational exposure.
The appropriate dosimetry program depends on the facility and applicable requirements.
How to Choose a Lead Apron
Choosing the right lead apron involves more than selecting a size.
Consider:
1. Lead Equivalence
Check the manufacturer's stated lead-equivalent protection and make sure it is appropriate for the intended application.
2. Coverage
Consider how much of the torso needs to be protected.
3. Fit
A properly fitted apron can provide appropriate coverage while improving comfort and mobility.
4. Weight
Heavier protective garments can become uncomfortable during extended use.
5. Design
Options can include front-protection and wrap-around configurations.
6. Intended Environment
A veterinary clinic, general radiography department, dental facility, and interventional environment may have different requirements.
7. Manufacturer Instructions
Always follow the manufacturer's instructions for use, cleaning, inspection, and storage.
How to Store Lead Aprons
Proper storage is important because protective garments can be damaged by inappropriate handling.
Lead aprons should not simply be folded and placed in a pile.
Follow the manufacturer's storage recommendations. In general, protective garments should be stored in a manner that prevents unnecessary creasing, compression, or physical damage.
Health Canada recommends that protective equipment be stored and maintained according to manufacturer instructions.
Inspecting Lead Aprons and Protective Equipment
Protective equipment should be inspected regularly for signs of damage.
Possible concerns include:
Cracks
Tears
Folds
Separation
Damaged seams
Visible physical deterioration
Areas suspected of reduced shielding
Visual inspection alone may not identify all internal defects.
Health Canada's medical Safety Code 35 calls for protective equipment to be tested annually for integrity, while veterinary Safety Code 28 recommends radiographic inspection annually or when damage is suspected.
Defective protective equipment should be removed from clinical use according to the facility's safety procedures and applicable requirements.
Common Radiation Safety Mistakes
Using Protective Clothing as a Substitute for Safe Positioning
Protective clothing should supplement safe working practices rather than replace them.
Standing in the Primary Beam
Protective gloves and aprons are not a reason to intentionally place a body part in the primary X-ray beam.
Improperly Storing Aprons
Folding or storing protective garments incorrectly can contribute to damage.
Ignoring Equipment Inspection
Protective equipment should be inspected and tested according to manufacturer instructions and applicable requirements.
Allowing Unnecessary Personnel in the X-Ray Room
Only people whose presence is necessary should remain in the room during an exposure.
Forgetting Dosimetry
Personnel who meet the facility's criteria for occupational monitoring should participate in the appropriate dosimetry program.
Failing to Train Staff
Everyone who participates in X-ray procedures should understand the facility's radiation-safety procedures.
Radiation Safety in Veterinary X-Ray
Veterinary X-ray environments have additional considerations because animals cannot always cooperate with positioning instructions.
Whenever practical, practices should use positioning and restraint methods that reduce the need for personnel to hold the animal.
If personnel must assist, Health Canada's veterinary guidance recommends protective aprons and gloves and emphasizes avoiding exposure to the primary X-ray beam. It also recommends considering sedation or holding devices when appropriate.
A veterinary radiation-safety program should be developed around the equipment, facility, procedures, staff responsibilities, and applicable provincial and federal requirements.
Radiation Safety in Medical X-Ray
Medical X-ray facilities also use multiple layers of protection.
These can include:
Shielded control areas
Protective barriers
Lead aprons
Protective gloves or gauntlets
Thyroid protection
Protective eyewear
Personal dosimeters
Equipment quality control
Radiation surveys
Staff training
Health Canada's current Safety Code 35 provides guidance for large medical radiological facilities, including protective equipment specifications, inspection, dosimetry, and operating procedures.
