Final answer:
BMET departments and service units have not always prioritized radiation protection, but it is crucial in medicine, as shown by studies on radiation exposure and the implementation of laws and regulations to limit exposure.
Step-by-step explanation:
Radiation protection has not always been the primary focus of BMET departments and service units. But protecting against radiation is essential in the medical field, particularly in nuclear medicine and imaging.
The study conducted on Russian nuclear workers, which demonstrated a connection between radiation exposure and different cancer types, serves as an illustration of the significance of radiation protection.
Laws and regulations are in place to limit radiation doses that people can be exposed to, both in occupational settings and for the general public. These regulations help ensure the safety of individuals working with radiation and those who may be inadvertently exposed to it.
