Commentaries: Art. 81

Working areas must be established within a controlled area in separate rooms reserved for these purposes.
They shall be classified into the following types, according to the activity of the radioactive materials handled per operation or per day:
1. type C: an activity from 1 to 100 times the licensing limit;
2. type B: an activity from 1 to 10 000 times the licensing limit;
3. type A: an activity from 1 times the licensing limit to an upper limit defined in the licensing procedure.
For the storage of radioactive materials in working areas, the supervisory authority may increase the values specified in paragraph 2 by up to a factor of 100.
The supervisory authority may allow exceptions to paragraph 1 on operational grounds, provided that radiological protection is assured.
The supervisory authority may in exceptional cases, where handling involves a low risk of intakes, increase the values specified in paragraph 2 by up to a factor of 10, provided that radiological protection is assured.
The supervisory authority may in individual cases, taking into account the risk of intakes, assign working areas to a different type from that specified in paragraph 2, provided that only activities involving a low risk of inhalation are carried out therein.
The FDHA, in consultation with ENSI, shall issue the necessary regulations concerning protection measures.
