Calculated depth dose tables for californium-252 sources in tissue

Abstract

Depth dose tables for 252Cf sources of various designs currently available for use in radiotherapy have been calculated. Tables are presented for 5 cm along the transverse axis and 5 cm along the source axis in steps of 0.5 cm. Gamma-dose due to the primary gamma -rays includes a correction for the self-absorption in the platinum- iridium wire on which the 252Cf is electrodeposited, in addition to the correction for absorption in the wall of the source.
