和放射有关的就是counts per minute The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time registered by a radiation monitoring instrument, of which counts per minute and counts per second are commonly used. This measurement is only of the rate of events registered by the measuring instrument, not the rate of events at the point of original emission. For radioactive decay measurements it must not be confused with disintegrations per unit time (dpm), which represents the rate of atomic disintegration events at the source of the radiation. Count rates are normally associated with the measurements of particles, such as alpha particles and beta particles. For gamma ray and X-ray dose measurements a unit such as the Sievert is normally used |
