WebPartly because they do not all measure the same thing. For example, cpm is merely the number of counts per minute; it says nothing about the energy of the incident radiation, and also requires correction for the detector efficiency, geometry, and other factors in order to arrive at conclusions about source strength; curies are a direct measure of source strength. WebTaking Background Radiation Measurements. We use the CPM mode of the Geiger counter to take background radiation measurements. Position the Geiger counter or the Geiger counter’s sensor in an area that is free from external radioactive sources. Take a minimum of 10 CPM measurements and log the CPM number in a notebook.
