WebConstruction Although the G-M tube has evolved over the years, the fundamental design has remained unchanged. The sizes and shapes of G-M tubes, and formulations of the counting gasses used are changed to optimize G-M tubes for specific applications. The G-M pancake is one such optimization. The shape of the tube itself is the reason for the WebG-M counters are mainly used for portable instrumentation due to their sensitivity, simple counting circuit, and ability to detect low-level radiation. G-M detectors are generally more sensitive to low energy and low-intensity radiations than are proportional or ion chamber detectors. Simpler Electronics.
