Handheld Contamination Monitor HCM-100 Of X-Ray Flaw Detector

Handheld α β γ contamination monitor HCM-100 can make measurement of radioactive surface contamination, provides high sensitivity for three, alpha, beta and gamma radiation. The instrument is therefore ideally suited for the measure ment of photon emitting radio nuclides, widely used in nuclear medicine as well as in other laboratories environments.It can test gross count, counting rate, nuclide activity, nuclide concentrationetc.
