title: Absorbed dose rate in tissue around uniformly loaded linear radium and 137Cs-sources encapsulated in platinum.
abstract: A method is described for calculating the absorbed dose rate in tissue around encapsulated linear radium- or 137Cs-sources. A variable factor is derived relating this quantity to the absorbed dose rate from the unshielded source in air. This factor depends on a set of geometrical parameters including some data concerning the shape of the source ends.
