A radioactive isotope in a suitable source holder is the prerequisite for
a radiometric measurement setup.
The handling of radioactive substances is regulated by law. The radia-
tion protection rules of the country in which the system is operated
apply first and foremost.
In Germany, for example, the current radiation protection ordinance
(StrlSchV) based on the Atomic Energy Law (AtG) applies.
The following points are important for measurement with radiometric
methods:
A handling permit is required for operation of a system using gamma
rays. This permit is issued by the respective government office or the
responsible authority (in Germany, for example, offices for environ-
mental protection, trade supervisory boards, etc.)
You can find further instructions in the operating instructions manual
of the source container.
