Abstract:
The biological shields of nuclear reactors are partly thick-walled concrete constructions which do not require special attention, as far as their strength is concerned. . .In this report some types of radiometric probes suitable for density measurement, as well as the results of the reactor shield construction of a nuclear power station, an experimental nuclear reactor, and a biological shield of a betatron are described. The RILEM program: comparision of commerical portable gages for radiometric determination of building materials density and moisture is discussed.
