The CoMo 170 is an efficient, portable contamination monitor
equipped with an innovative detector technology for the high sensitive and nuclide
referred measurement of surfaces regarding alpha, beta and gamma contaminations.
The detector technology with thin plastic scintillation detector completely
works without gas-filled or gas flow proportional detectors, thus avoiding expensive
costs for consumable gas or for repair of Xenon detectors.
Measurement of alpha, beta and gamma radiation with only one detector. The
measuring system automatically identifies the existence of alpha radiation. It is
possible to effect a simultaneous, selective measurement of alpha and beta/gamma
contaminations.
A defective detector foil can be replaced by the
user himself. An expensive repair by the manufacturer is not necessary.
The nuclide referred efficiencies of the
scintillation detector can be compared with the efficiencies of common counter
tubes.
