Dose to persons assisting voluntarily during X-ray examinations of large animals.

The research study investigates radiation exposure suffered by pet owners who often voluntarily assist during their pets’ X-ray examinations, despite not being regularly monitored for radiation exposure like the medical staff is. The study evaluates the potential need for changing German regulations to include dose measurements for these volunteers.

Purpose of the Study

• The main aim of this research is to explore whether the German regulation should be amended to require dose measurements for individuals who willingly assist during X-ray examinations of their pets.
• A secondary goal of the study was to determine the radiation dose exposure these volunteers experience.

Methodology

• The researchers measured the personal dose equivalent, Hp(10), which is a calculated estimate of the dose a person would receive from radiation, for volunteers in different X-ray examination scenarios involving large animals, especially horses.
• They identified typical exposure situations and performed measurements in the field of scattered X-rays, to understand where the most radiation exposure probably occurs.
• Measurements were carried out both in real-life veterinary practices on animals during medical examinations, and under laboratory conditions, to validate the findings.

Findings and Conclusion

• The findings show that the measured personal dose equivalent values of these volunteers in horse radiology are of the order of a few microsieverts—units of radiation dose.
• The conclusions drawn from these findings may serve to guide legislation in Germany on how to treat similar situations of voluntary support during X-ray examinations in future. This could involve the requirement for dose measurements for these volunteers, using personal dosemeters or other methods.
