Abstract
A radiation analyzer which measures radiation from a plurality of radiation sources in a single measurement cycle to distinguish between the radioactivity level received from a plurality of radiation sources. The radiation level of one of the sources may be known so that that source serves as a radiation standard with which to compare the other sources. Alternatively, the sources may all be known and the comparative radioactivity levels utilized to obtain information concerning some other parameter, such as external attenuation.
