The electronics module PT30E.XX is a replacement part for radiation-
based sensors MINITRAC 31.
The electronics module can only be exchanged by VEGA service
technician.
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
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 radiation-
based 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.
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:
