I tested the Geiger counter at home and at work and in all kinds of rooms, granite counter tops, and the CPM was low (0-50 is background). The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time as registered by a radiation monitoring instrument, for which counts per minute (cpm) and counts per second (cps) are commonly used quantities.. Count rate measurements are associated with the detection of particles, such as alpha particles and beta particles. The SI-3BG barely registers one count per minute at background but it goes to 300 Roentgen per Hour (Open Reactor Core levels). The range of intensity that can be measured with a given counter will usually extend to about 10 times the lowest value for which the counter will give a satisfactory reading. However for general purposes I consider them the one and the same. Price: $199.99. The Geiger counter, also known as the Geiger-Mueller counter, is electrical device that detects various types of ionizing radiation.This device is named after the two physicists who invented the counter in 1928.
