A conversion from counts per second (cps) to dose rate (Gy h -1, Sv h -1, etc.) is possible, but the conversion factor depends on the kind of detector being used and on the type of radiation being measured and frequently on the energy of the radiation. The relationship between count rate and dose rate is usually established through empirical ...
WebThe activity or intensity of radiation is measured in counts per second ( cps ), which expresses a rate of counts per unit time registered by a radiation monitoring instrument. In general, commonly used quantities are: counts per minute (cpm) counts per second (cps) The best-known counter is the Geiger-Müller counter.
