Lightweight, compact Geiger counters for measuring ambient equivalent dose and dose rate from gamma and X-ray radiation, from 17 keV.
The RadEye G20-10 and G20-ER10 are lightweight, compact Geiger counters for measuring ambient equivalent dose and dose rate. They are suitable for dose rate measurements on X-ray scanners and for medical isotopes including I-125. Typical users include nuclear medicine, the nuclear industry, civil defence, fire brigades, hospitals and the pharmaceutical industry.
The two models differ in upper dose rate limit: the G20-10 measures up to 2 mSv/h and the G20-ER10 up to 100 mSv/h. The meters have a menu-driven user interface, a large internal memory for scaler results and continuous data recording, and plain-text messages in several languages. Audible indication is given as single pulses or in chirper mode proportional to count rate.
