Nuclear medicine personnel working with medical isotopes or in facilities that use radiation must constantly monitor their exposure risk. Protect employees and comply with occupational safety regulations with X-ray and gamma-ray survey meters. These lightweight and compact Geiger counters are ideal for ambient equivalent dose and dose rate measurement, with a flat energy response curve from 17keV to 1.3MeV according to the ambient equivalent dose H*(10). The RadEye G20-ER10 model covers the entire dose rate range from background to 100 mSv/h.
