Abstract
Measurements of the transmission of Ra(B + C) γ rays through lead between 0 and 26 cm. are described and compared with the transmissions predicted on the basis of a modified version of the γ-ray spectrum of Ellis and Aston and on the basis of the spectrum of Latyshev et al. Ellis and Aston's spectrum gives the better agreement. Both the relative and absolute values of the γ-ray intensities given by Ellis and Aston are revised in the light of more recent information. This revised spectrum leads to a predicted value of 0.84 roentgens per hour at a meter for the γ-ray output of a gram of radium and its equilibrium products in 0.5 mm. of platinum, in good agreement with experiment.Keywords
