What is the dose limit for the general public regarding exposure to radiation?

The appropriate dose limit for the general public regarding exposure to radiation is set at 1 mSv (100 mrem) per year. This limit is established by organizations such as the National Council on Radiation Protection and Measurements (NCRP), the International Commission on Radiological Protection (ICRP), and regulatory bodies as a safety precaution to minimize the risk of harmful effects from radiation exposure in individuals who are not occupationally exposed to radiation.

Radiation exposure above this limit increases the potential risk of adverse health effects, including cancer, so the lower limit for the general population helps to ensure safety and protect public health. The distinction between doses for workers and the general public aligns with the understanding that occupational exposure might be justifiable due to the nature of their work, while the general populace should have stricter limits to safeguard those who are not trained or equipped to handle such exposures.

In context, the other options propose limits substantially higher than what is deemed acceptable for the general public, which could increase health risks beyond acceptable levels.
