CPO
Contamination and Clearance -CheckPoint: Waste
CPO
Tool Monitor
The tool monitor (CPO) is a stand-alone equipment
which main function is to detect the radioactive
contaminantion left on tools leaving any nuclear work
area where contamination risks exist. It allows
monitoring of various equipment sizes from pens to
tools box, or even long size objects such as piping or
cable through sequential monitoring check.
The CPO featured a reliable contamination detection
as the objects are stationary during the entire
monitoring period minimizing the typical errors
induced by monitoring through mobile and manual
detector. An audible and visual signal is actuated
when exceeding a preset threshold.

FUNCTIONAL CHARACTERISTICS
Detection is performed by two large plastic scintillators,
sensitive to γ rays. Each scintillator is connected to an
ampli er/discriminator, providing two separate detection
channels.
The pulses output from the detectors are transmitted to a
microprocessor which computes:
●
Assessment of contamination level
Calculation of background ●
Management of visual and audio signals ●
Acquisition of operating instructions ●
PHYSICAL CHARACTERISTICS
Performances depend on dose rate, level of con dence,
measurement time and the isotope concerned.
It is possible to detect less than 140 Bq for 60Co, in a
natural radioactive environment, with a measurement
time of 10 s and a con dence level of 95%.
