What is the regulatory limit for radiation exposure per year for a monitored individual?

The regulatory limit for radiation exposure per year for a monitored individual is 5000 mR, which is equivalent to 5 Rem or 50 mSv. This limit is established by the National Council on Radiation Protection and Measurements (NCRP) and the Environmental Protection Agency (EPA) to safeguard individuals who work in environments where radiation exposure is possible.

This exposure limit is designed to minimize the risk of radiation-induced health effects while allowing individuals to perform their work safely. It also considers occupational exposure and takes into account the need for workers to have some level of access to potentially hazardous environments as part of their job functions.

In practice, this limit serves to protect the health and safety of personnel in radiation-related occupations, ensuring that cumulative exposure remains within levels that medical research indicates do not lead to a significant increase in the probability of harmful effects, such as cancer.
