A survey of the radiation safety practices of veterinary practitioners during portable equine radiography in Ireland.

Overview

• This study surveyed veterinary practitioners in Ireland to evaluate their radiation safety practices when performing portable radiography on horses.
• The goal was to assess adherence to safety guidelines and identify areas for improvement to minimize occupational exposure to ionizing radiation.

Background and Rationale

• Portable radiography is commonly used in equine veterinary practice for diagnostic imaging.
• Veterinary practitioners and any assisting staff are exposed to ionizing radiation during these procedures, which carries health risks if not properly controlled.
• Radiation safety protocols, training, and protective measures are essential to minimize exposure.
• In Ireland, guidance from the Environmental Protection Agency (EPA) outlines best practices for radiation protection.
• Understanding current practices helps identify gaps and improve safety measures.

Methods

• An online survey was distributed to veterinary practices registered with the Veterinary Council of Ireland that have at least 20% equine caseload.
• The survey included questions about:
• Radiation safety training received by the practitioners
• Implementation and adherence to radiation safety protocols
• Usage of personal dosimeters to monitor radiation exposure
• Use of lead protection equipment, such as aprons and gloves
• Frequency of repeat radiographs, which can increase cumulative radiation dose
• The role of sedation in reducing patient movement and need for retakes
• Personnel roles and whether appropriate distancing and shielding are used

Key Findings

• Overall, adherence to EPA radiation safety guidelines among equine veterinary practitioners was reasonably good.
• However, certain areas showed room for improvement:
• Personal dosimeter usage was suboptimal, meaning some practitioners may not be effectively monitoring their radiation exposure.
• Repeat radiograph rates could be reduced, possibly by optimizing positioning, sedation, or technique to avoid unnecessary exposure.
• Lead protective equipment usage and following strict protocols was generally well adopted but could still be improved for consistency.

Implications and Recommendations

• The findings highlight the importance of ongoing radiation safety training and awareness for veterinary practitioners performing portable equine radiography.
• Improved compliance with dosimeter use would enable better monitoring and management of occupational radiation dose.
• Efforts to reduce repeat exposures, via better sedation or technique, would further minimize cumulative radiation risks.
• Ensuring consistent use of lead protection and adherence to protocols can protect all personnel involved in radiographic procedures.
• Overall, these improvements help maintain radiation exposure As Low As Reasonably Achievable (ALARA), protecting veterinary practitioners’ health.

Conclusion

• This survey provides valuable insights into the current radiation safety practices in Irish equine veterinary radiography.
• While adherence to EPA guidelines is generally satisfactory, targeted improvements in dosimeter use and reduction of repeat exposures are recommended.
• Such enhancements are crucial for safeguarding occupational health in veterinary practice through minimized ionizing radiation exposure.
