LB 123 UMo - universal monitor for radiation protection applications
The LB 123 is not just one instrument, but is a complete system of
radiation protection instrumentation. It covers measurement of surface
contamination, gamma doserate, neutron doserate and activity. A variety
of different contamination detectors enables the measurement of
alpha/beta-emitters, beta/gamma-emitters and even of tritium.
The LB 123 consists of a battery driven datalogger unit, where one of seven
available radiation detectors could be connected. High voltage-supplies,
preamplifiers and discriminators are integrated in the probes, which
are identified automatically by the system. Operation of the LB 123 is
very simple. The micro-controller program provides many useful functions
and utilities like for instance background measurement with automatic
subtraction, scaler-timer-mode, autorepetitive mode, dose-integration,
plateau-measurement, storage of up to 250 measured values.
