BESSY II Radiation Safety Requirements
Due to the current situation of the regulatory authority, the planned changes (see below) will not take effect at 1st of April, but presumably at 27th of April. Until then (01.04. - 26.04.) the experimental hall remains controlled area, and regular access for external users and companies following § 25 StrlSchV is prohibited. Access following the 7-day regulation remains possible (when deemed necessary and the usual prerequistes are fulfilled).
Upcoming changes in April 2020
Presumably starting 27th of April 2020, most of the experiment hall of BESSY II (i.e. the area between the outer walls and the shielding walls*) will no longer be a controlled area but a surveillance area, and the users working there are no longer required to have the status as radiation workers. Access to surveillance areas can be granted without radiation passport, confirmation letter and RPDC; but we do need your SSR number, so you can be given a personal albedo dosimeter**. All other requirements and restrictions listed below will remain unchanged.
*Everything circled by the outer shielding wall, including the area above the storage ring, housing the IRIS and THz beamline, remains a radiologically controlled area.
**Exceptions exist within the framework of the 7-day regulation exclusively for guided visitor groups, users of the MX beamline, and service personnel with whose company no delimitation agreement has yet been concluded.
Access to radiation protection areas at HZB, Adlershof site
The following requirements/documents must be fulfilled/provided by guests who wish to access the radiologically controlled areas at BESSY II (including the entire experimental hall), the MLS, HoBiCaT and bERLinPro:
- Radiation Protection Delimitation contract with HZB (or German version)
- Radiation Protection Register (SSR) number
- Radiation passport; if German, it must be registered and actualised to 2 months, and SSR- and company number must be entered on page 3
- GATE registration for users oder POFSTA registration for service personell
- Radiation protection and safety training (validity 1 year)
- Registration to the beamline via the responsible beamline scientist, time for installation should be included
- German companies only: valid §25 authorisation; available from the competent state offices for health and safety at work
These requirements apply in principle to anyone wishing to gain access to radiation protection areas. Exceptions exist within the framework of the 7-day regulation exclusively for guided visitor groups, users of the MX beamline, and service personnel with whose company no delimitation agreement has yet been concluded.
Private persons may only be allowed access within the framework of a guided tour.
Persons under 18 years of age, pregnant women and nursing mothers, persons with open wounds, as well as persons who lack one of the prerequisites, are prohibited from access.
Eating and drinking as well as the use of skin creams is forbidden in radiologically controlled area.
If you have any questions concerning the delimitation contract, the §25 approval and the radiation passport, please contact your radiation protection officer. As a rule, the radiation protection officer knows whether the documents already exist.
