Radiation Safety. The guiding principle of radiation safety is “ ALARA ”. ALARA stands for “as low as reasonably achievable”. This principle means that even if it is a small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measures in radiation safety: time ...A radiation worker is defined as an employee 18 years of age or older that over the course of a year is likely to exceed 100 mrem.
