Facts: Radiation in Veterinary Medicine

Diagnostic radiology is an essential part of present-day veterinary medicine. While there are benefits to the animal being X-rayed, precautions must be taken to reduce the possible harmful effects of ionizing radiation to the operator.

The Risks

During an average veterinary radiological examination, the radiation dose received by an operator is generally low. The body's defence mechanisms act upon exposed cells in an attempt to repair any damage. While an individual's immune system, age, or sex may dictate the speed and effectiveness of the body's ability to repair cells, exposure to ionizing radiation, even at low doses, may cause irreversible damage. Therefore, the effect of even low levels of ionizing radiation may accumulate and could represent a potential health hazard.

Safeguarding Your Health

Veterinary workers can minimize exposure risks by following documented safety procedures and using dosimeters. Dosimeters are small devices that monitor an individual's exposure to X-ray, beta, and gamma radiation. Dosimeters are worn for a specified period of time and then returned for processing and analysis. An exposure report is generated and identifies any radiation exposure incurred during the wearing period.

There are several reasons why a veterinary worker should wear a dosimeter:
