Radon information for exposed workers

2013/59/EURATOM Directive

”In the cases where the exposure of workers is liable to exceed an effective dose of 6 mSv per year or a corresponding time-integrated radon exposure value, they are managed as a planned exposure situation and that dose limits apply.”

Article 9. Dose limits for occupational exposure

1. Member States shall ensure that dose limits for occupational exposure apply to the sum of annual occupational exposures of a worker from all authorised practices, occupational exposure to radon in workplaces requiring notification in accordance with Article 54(3), and other occupational exposure from existing exposure situations in accordance with Article 100(3).

IAEA: ”Exposure to radon in the workplace is normally subject to the requirements for existing exposure situations. However, the requirements for planned exposure situations apply to:

(a) Exposure to 222Rn, 220Rn and their progeny in workplaces in which occupational exposure to other radionuclides in the 238U or 232Th decay chains is controlled as a planned exposure situation;

(b) Exposure to 222Rn and its progeny in workplaces in which the annual average activity concentration of 222Rn in the air remains above the reference level. ”
