3.5 Corresponding source container
A radioactive isotope in a suitable source holder is the prerequisite for
a radiation-based measurement setup.
The handling of radioactive material is regulated by law. The radiation
protection rules of the country in which the system is operated apply
rst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 radiation-
based methods:
A handling permit is required for operation of a system using gamma
rays.Thispermitisissuedbytherespectivegovernmentoceorthe
responsibleauthority(inGermany,forexample,ocesforenviron-
mental protection, trade supervisory boards, etc.)
Youcanndfurtherinstructionsintheoperatinginstructionsmanual
of the source container.
When handling a radioactive source, unnecessary radiation exposure
must be avoided. An unavoidable radiation exposure must be kept as
low as possible. Take note of the following three important measures:
