Walter Mueller, a graduate PhD student of Geiger's, perfected the gas-sealed detector in the late 1920s and received credit for his work when he gave his name to the Geiger-Mueller tube. There is no substitute for the equipment needed to detect and protect. Because background radiation rates vary randomly, you might see that range standing in one spot. Ionizing radiation on the other hand can strip atoms of their electrons, in a process called ionization. Radiation energy detected by some devices is registered as a "count." Devices detect only a percent of the total energy (radioactive decays or disintegrations) released by radioactive material. When radiation reaches the counter, it ionizes the gas, freeing negatively charged electrons from atoms and creating positive ions from the part of the atom that remains. A Geiger counter, also called a Geiger-Mueller tube or G-M counter is a device that can measure radiation particles. They can then reliably convert the clicks into measurement units, such as mR/hr or mSv/hr. Digital Nuclear Radiation Detector Dosimeter Geiger Counter Dose Device Monitor Portable with Dosage Rate Alarm .

The Geiger counter, also known as the Geiger-Mueller counter, is an electrical device that detects various types of ionizing radiation. Intrinsically safe options are available for users that may operate them in explosive environments. The fact that they offer this shows just how accurate their Geiger counters are. At high rates of radiation, the tube is not so accurate because each event of ionization is followed by an intensive period called dead time, during which any further incident radiation does not contribute to a count. Truth be told, I wouldnt keep it in my BOB all the time. It applies to a very specific type of detector, and generally to a specific application of that detector. But the Geiger counter is an instrument sensitive enough to detect ionization. I developed emergency and disaster plans around the globe and responded to many attacks and accidents as a HAZMAT technician.
