Radiation Monitoring Device Handheld α β γ Contamination Monitor DH80 with 4 multi-function keys

Handheld α β γ contamination monitor DH80 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 concentration etc. can test food, auto parts, and other objects etc
