Radioactivity Monitoring of Charge
Buckets in Steelworks
Engineering skill is required when adding sophisticated monitoring systems for
radioactivity to the normal operations and sequences in production plants such as steel
works.
The example shows the integration of a FHT 1388 type radioactivity monitor into
transporters for charge buckets.
Two large radioactivity detectors continuously monitor the process of loading with
scrap and the transport to the works. In spite of tough environmental conditions and
physical stress by mechanical shocks and magnetic fields the installed system is active
since 1998. Careful shock absorbing construction, magnetic shields are essential.
A highly variable natural background radiation is efficiently compensated by the NBR
-technique for natural background reduction and thus most sensitive detection of
artificial radiation sources is achieved.

The photos show details of detectors on the remotely
controlled charge bucket ferries. The buckets have a loading capacity of about 60m3. The
detectors are positioned in a distance of about 1meter. |
