Radiological Protection Ordinance
(RPO)

¹ Work­ing areas must be es­tab­lished with­in a con­trolled area in sep­ar­ate rooms re­served for these pur­poses.

² They shall be clas­si­fied in­to the fol­low­ing types, ac­cord­ing to the activ­ity of the ra­dio­act­ive ma­ter­i­als handled per op­er­a­tion or per day:

a.

type C: an activ­ity from 1 to 100 times the li­cens­ing lim­it;

b.

type B: an activ­ity from 1 to 10 000 times the li­cens­ing lim­it;

c.

type A: an activ­ity from 1 times the li­cens­ing lim­it to an up­per lim­it defined in the li­cens­ing pro­ced­ure.

³ 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.

⁴ The su­per­vis­ory au­thor­ity may al­low ex­cep­tions to para­graph 1 on op­er­a­tion­al grounds, provided that ra­di­olo­gic­al pro­tec­tion is as­sured.

⁵ 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.

⁶ 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.

⁷ The FDHA, in con­sulta­tion with EN­SI, shall is­sue the ne­ces­sary reg­u­la­tions con­cern­ing pro­tec­tion meas­ures.
