摘要：

The variance of the (Poisson) counting statistics of a typical nucleonic instrument is shown to be expressible as the sum of contributions from a -variety of distinct random processes. The utility of this decomposition is illustrated in an example where the effect of the random decay rate of the isotope is removed. Contradicting numerous articles and texts, it is also shown that the random decay rate of the isotope and the random detector counting statistics do not participate in a cause-effect relationship, but are nearly independent phenomena in most instruments. © 1969, American Association of Physics Teachers.
