In terms of radiation safety, what is an important principle regarding shielding?

The principle regarding shielding in radiation safety emphasizes that it should be used selectively, based on exposure. This principle is grounded in the understanding that not all scenarios involve the same level of risk from radiation exposure, and therefore, shielding must be applied in contexts where it can effectively reduce exposure to individuals.

The effectiveness of shielding relies on the type of radiation involved and the specific circumstances, such as the type of radiation (alpha particles, beta particles, gamma rays, etc.), the source of radiation, and the duration and intensity of exposure. Using shielding selectively helps to ensure that resources are utilized efficiently, targeting protection where it is needed most rather than applying blanket measures that may not be necessary in all cases.

This selective use helps to maintain safety while balancing operational efficiency and practicality, thereby contributing to a safer environment for both workers and the public in contexts where radiation exposure may occur.
