What is the maximum permissible dose for the general public according to the NCRP?

The maximum permissible dose for the general public, as recommended by the National Council on Radiation Protection and Measurements (NCRP), is set at 1 mSv per year. This limit is established to minimize the risk of radiation exposure for individuals who are not occupationally exposed to radiation.

The rationale behind this dose limit includes the need to protect members of the public, especially vulnerable populations such as children and pregnant women, from the potential harmful effects of ionizing radiation. The NCRP takes into account both natural background radiation and additional exposure from human-made sources when establishing these guidelines.

The choice of 1 mSv is based on a careful consideration of the potential health risks associated with long-term low-level exposure to radiation, aiming to keep cancer risk and other health effects within a statistically acceptable range. This measure serves as a benchmark to ensure public health safety while allowing for necessary medical and industrial applications that may involve higher doses for specific populations or situations.
