Regarding public exposure limits, what is the annual limit set by NCRP #116 for continuous or frequent exposures from artificial sources other than medical exposure?

The annual limit set by the NCRP (National Council on Radiation Protection and Measurements) #116 for continuous or frequent exposures from artificial sources other than medical exposure is indeed 1 mSv. This standard reflects the NCRP's commitment to protecting public health by minimizing unnecessary radiation exposure.

The 1 mSv limit is designed to ensure that the population as a whole is not subjected to excessive radiation doses from various artificial sources, which include industrial activities, nuclear power plants, and other non-medical sources of radiation. This limit balances the benefits of technology that produces radiation while safeguarding public health from potential adverse effects associated with cumulative radiation exposure.

By establishing this threshold, the NCRP aims to promote safety and encourage the justification of activities that may lead to radiation exposure. Ensuring that public radiation exposure remains at or below this limit is critical for long-term health considerations and supports a precautionary approach to radiation protection.
