The principle of whole-body counting is widely applied to various fields of science. Much emphasis has so far been laid on the detection of a very small quantity of radioactivity, thus strenuous efforts having been made to improve sensitivity and energy resolution of equipments. In order to accomplish the purpose of radiation protection effectively, however, the following three points become more important. Namely, <BR>(1) Clearifying the role of whole-body counting in the radiation protection service.<BR>(2) Giving the whole-body counter the function as an individual monitor of internal exposure.<BR>(3) Utilizing the whole-body counter more easily and frequently, feeding the result back to the radiation protection service rapidly.<BR>The present paper gives some basis for the argument that a simplified whole-body counter can meet these requirements satisfactorily, and that effective and economical radiation protection can readily be accomplished by this simplification. The basic properties required of the simplified whole-body counter for the monitoring purpose are considered in view of efficiency of detectors, its mechanism, and the way of utilizing it in the routine monitoring program. As an example, the paper describes the outline of the simplified whole-body counter intended to be installed in a certain nuclear power station.
