# Radiological limits

Radiological Limits give radiation limits for workers, apprentices and students, and members of the public. The values given are recommended by international organisations such as Euratom, ICRP, and IAEA and the national German authorities. A typical radiological limit for radiation workers is 20 mSv/y (20 milli Sieverts per year). For members of the public, the radiological limit is much lower at 1 mSv/y.
