Why does radiation safety matter?
The smallest amount of radiation exposure can pose a health risk to the whole practice. Veterinary technicians may be particularly at risk, as they typically capture x-ray images. X-rays scatter in all directions, even when an animal is sedated and/or positioning devices are used.1
There are potential side effects of radiation exposure including increased risk of cellular damage that can have health consequences.2

Protect your team
Implement exposure precautions and occupational dose limits.
Lower the dose with ALARA
ALARA stands for "as low as reasonably achievable." This radiation safety principle4 offers simple guidelines for veterinary technicians, including these:
Minimize the time
Limit time in the x-ray suite and avoid retakes by using a technique chart.
Double the distance
Maintain distance between the body and the radiation source using sedation and sandbags or nonmanual restraints to secure patients.
Use personal protective equipment
Use absorber materials like lead aprons, gloves, and thyroid shields, as well as permanent barriers.
Follow your state's radiation guidelines
Make sure your practice is following your state's local radiation guidelines. Find your state's current guidelines here.
Safe imaging is optimal imaging. Make radiation safety a priority at your practice.

Achieve Lowest-Dose Radiation: Radiation Safety Is Your Safety
This presentation reviews the use of the ALARA principle (as low as reasonably achievable) as well as optimization of image and dose by applying ALARA. ALARA guidelines on education, equipment selection, and anatomic radiographic techniques selection help reduce veterinary patient dose, which reduces occupational staff and general public exposure as well.
