Servicing and Maintenance

7.1

Source Container

Radiation regulations vary from country to country. The UK regulations require periodic
leak tests of the sources in the container. Contact Tracerco for more information.

7.2

PRI150 Radiation Detector(s)

The intrinsically safe nature of the PRI150 radiation detector means that there are no user
serviceable parts. Any servicing or maintenance work on the detector must be carried out
by trained personnel to strict procedures to ensure the safety of the device. Contact
Tracerco for more information.

7.3

Optimus™ Control Module

There are no user serviceable parts in the Optimus™ control module.
