Abstract
Tables, calculated by the ACCEPT and other Monte Carlo codes, are presented for dose distributions in water produced by monoenergetic electrons and by 120 or more beta-ray and conversion-electron emitters in three geometrical arrangements: a point isotropic source in an infinite water medium; an isotropic source distributed uniformly over a circular area of either 1 cm{sup 2} or 100 cm{sup 2} on an air-water boundary; and, a broad parallel beam incident normally on the surface of water. A method of deriving distributions in other low-Z media from these tables is given. From the results, some deductions are made on the variation of H`(0.07)/fluence, for normal incidence, and on the backscatter factors of air and water as a function of maximum beta energy, for plane isotropic sources.
