The Absorption of Gamma Rays by Barium Sulphate Plaster, Water and Beef

Natural Philosophy Department, University of Melbourne

This excerpt was created in the absence of an abstract.

The absorption of the rays from Ra (B+C) in barium sulphate plaster, water and beef, has been investigated by a photographic method. The results obtained for the absorption of rays in this plaster are compared with those of Kaye, and of Sievert and Thoræus, for the absorption of X rays. The thickness of plaster for adequate protection against X and rays are discussed.

The emergent intensities of rays for different thicknesses of beef, up to 20 cm. have been measured.
