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 substances is regulated by law. The radia-

tion 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 radioactive sources, 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:
