BIM 201K
Beta Irradiation Monitor
The BIM 201K forms part of the RAMSYS product
line. It is an in-line monitor designed to detect beta
radiations in process and ef uent lines in nuclear
power plant or nuclear facilities. The BIM 201K has
been developped for continuous unattended opera-
tion and can cover beta measurement ranges requi-
red by regulations and industry guidelines. It is mainly
adapted for in-line monitoring to continuously mea-
sure beta volumetric activity in gaseous ef uent.
