Practices involving radiation sources require a licence in accordance with the Strahlenschutzgesetz (Radiation Protection Act – StrSchG). According to section 3 (73) of the StrSchG "practice" is defined as "a human activity that may increase the exposure of persons to radiation from a radiation source and is treated as a planned exposure situation".
Companies that carry out activities with naturally occurring radioactive materials are also subject to the licensing or reporting requirement in accordance with the StrSchG, unless an exception provision under the Allgemeine Strahlenschutzverordnung (General Radiation Protection Ordinance – AllgStrSchV) applies.
Depending on the type and hazard potential of the intended practice, radiation protection law provides for different licensing procedures:
- Two-stage licensing procedure: If radiation protection measures are required already at the time of the setting up of facilities, a two-stage procedure is to be applied (sections 15, 16, 17 of the StrSchG). The first step is to obtain a construction licence and the second step is to obtain a licence to carry out the practice.
- One-stage licensing procedure in accordance with sections 15, 17 of the StrSchG
For X-ray facilities with a nominal voltage of up to 100 kilovolts, the following applies. Provided that the necessary structural radiation protection measures are available, a two-stage licensing procedure can be dealt with in a joint authority procedure (section 9 of the AllgStrSchV).
Please note
It must be clarified in advance with your competent radiation protection authority whether a joint authority procedure is possible in a specific case.
Any modification of a practice or of structural radiation protection measures is also subject to authorisation (section 18 of the StrSchG). Such an application must be submitted to the licensing authority. The procedure is similar to an initial licence.
A central prerequisite for a licence according to sections 15 to 17 of the StrSchG is radiation protection expertise in the company. For this purpose, the company must appoint a "radiation protection officer" with respect to the authorities. This person must have received radiation protection training from an officially authorised training centre in addition to the relevant education. The central tasks of the radiation protection officer are defined in section 64 paragraph 1 of the StrSchG. It is important to note that it is the licence holder who is responsible to the radiation protection authority for compliance with the provision of radiation protection law, not the radiation protection officer.
A special case is an approval according to section 77 of the StrSchG for companies whose employees carry out work as so-called "outside workers". This is the case if the workers do not carry out work in their own company but in other companies in controlled or supervised areas and are to be classified as workers exposed to radiation. In such cases, both companies are responsible for the protection of the workers; additional regulations apply, such as the keeping of a radiation protection pass for external workers working abroad (section 81 of the StrSchG and section 118 of the AllgStrSchV).
Also, there is the special case of approval of a certain type of equipment, which is used in larger quantities, within the scope of type approval. If a device has such a type approval, the company that wishes to use such a device is not required to obtain a permit in accordance with sections 15 to 17 of the StrSchG. However, there is an obligation to notify the competent radiation protection authority, for example, before the device is used for the first time (section 35 paragraph 4 of the StrSchG and section 25 of the AllgStrSchV).
Please note
The licensing authority reviews the licensed practice in accordance with section 61 of the StrSchG. In doing so, compliance with the relevant regulations (the StrSchG and the AllgStrSchV). and the contents of the licence are checked. The prescribed interval depends on the type of practice.
