Radiation hazards from horses undergoing scintigraphy using technetium-99m.

This study explores the radiation exposure risk to staff from horses that have been through scintigraphy, a diagnostic imaging technique, using a radioactive material known as technetium99m methylene diphosphonate.

Research Background

• Scintigraphy is a diagnostic method that uses a radioactive tracer, in this case, technetium99m methylene diphosphonate (99Tcm-MDP), for imaging inside the body.
• This imaging technique is commonly used in equine medicine for tracing pathologies, particularly in the skeletal system.
• The study aims to assess the potential radiation risks associated with this procedure to the personnel, including veterinarians and staff, and the horse owners.
• The study incorporates the consideration of legal radiation exposure limits in accordance with the Ionising Radiations Regulations 1985.

Methodology

• The researchers measured the level of surface and environmental radiation from horses undergoing scintigraphy.
• This included monitoring the radiation levels from urine-contaminated bedding, which can be a significant secondary source of radiation exposure.

Outcome

• The data collected was used to create a safer working protocol that limits radiation exposure while still providing effective diagnostic results.
• Both high and low radiation levels were taken into account when assessing the potential hazards to ensure that all possible scenarios were considered.
• The research allows for safer implementation of equine scintigraphy by offering practical ways to protect those involved in the procedure from excess radiation exposure.
