The GEM100 is a handheld, battery-operated radioactivity measuring instrument consisting of a detector probe connected by coiled lead to an electronic un it. The detector is an end-window Geiger-Muller tube fitted with a protective grille. This can easily be removed to
allow closer access to the window hence increased sensitivity.

The instrument has two basic modes:
Ratemeter, which displays measured activity in counts per second (cps) and Scaler to display measured in a fixed or user determined time period.
