What is the maximum safe exposure limit for general public whole body exposure to radiation per year?

The correct answer regarding the maximum safe exposure limit for the general public for whole body radiation is 0.1 rem/year. This value is established by regulatory organizations to protect the health of individuals who are not occupationally exposed to radiation. The limit is designed to minimize potential health risks associated with radiation exposure, such as cancer, while allowing for the necessary use of radiation in medicine and other fields.

In contrast, occupational exposure limits for radiation workers are significantly higher, often around 5 rem/year. This difference reflects the increased training and safety measures in place for those whose jobs involve handling radioactive materials.

The lower limit for the general public is a precautionary approach, acknowledging that even low levels of radiation can carry some risk, especially in sensitive populations such as children and pregnant women. Therefore, minimizing exposure to 0.1 rem/year is a standard that helps ensure public safety without compromising necessary medical or industrial applications of radiation.
