WebThe ionization survey meter has a constant response over a range of photon energy, while a Geiger counter reading varies by a factor of 2-3 depending on photon energy. Ionization survey meters operate in current mode, Geiger counters in pulse mode. What is involved in accuracy testing of a gas-filled detector? WebWhat is a normal reading on a Geiger counter? The overall amount is what means the most. It’s normal to find a range of 7-30 CPM in surroundings. In my opinion, anything below 150 CPM is considered safe, but if the value overshoots this limit, the substance or atmosphere is dangerously radioactive.
