DETECTORS
A variety of type tested detectors is available to
transform the physical quantity “nuclear radiation”
(e.g. particle fl ux or dose rate) into a electrical signal:
• Gamma ionization chambers for dose rate monito-
ring
• Beta ionization chambers for noble gas monitoring
• Gamma and beta scintillation detectors for activity
monitoring
• Large-area silicon detectors for alpha and beta
monitoring
• GM-detectors for simple applications
• BF3 proportional counter tubes for sensitive
neutron monitoring
DIGITAL SIGNAL PROCESSING CHANNELS
Digital electronic channel systems TK 250 are
designed for signal processing of dose rate and
activity monitors. They are characterized by effi cient
functions, a comfortable operators menu structure
and a reliable and rugged operational behaviour.
Hardware and software are organized in modules.
This results in a high fl exibility to adapt to different
applications and customer needs.
Interfacing of pulse detectors and ionization
chambers is achieved by different preamplifi ers or
input boards. Remote operated test generators on
the input boards and signal simulation at different
points of the digital
processing sequence
allow effi cient proce-
dures for periodical
testing.
Hardware and software
of the system are type
tested according to
KTA 1505 and KTA
3505, therefore it may
be used for functions
of category A and B of
IEC 61226.
