What is the maximum radiation exposure limit for workers typically set at?

The maximum radiation exposure limit for workers is typically set at 5 rem (or 0.05 sievert) per year. This limit is established to ensure safety while allowing for some exposure in controlled environments, such as those encountered in nuclear facilities and certain industrial applications.

The reasoning behind setting the limit at 5 rem is based on scientific research assessing the long-term health effects of radiation exposure. It represents a balance between allowing necessary occupational exposure for workers in the nuclear industry while minimizing the risk of radiation-induced health issues, such as cancer. Organizations like the National Council on Radiation Protection and Measurements (NCRP) and regulatory bodies like the Occupational Safety and Health Administration (OSHA) have developed these guidelines to protect workers without unduly restricting their ability to perform their jobs.

In contrast, the other options reflect exposure limits that are either too low or do not account for the recognized risks associated with occupational exposure to radiation.
