Experimental determination of 32P dose backscatter factors at and near soft‐tissue boundaries
Abstract
Beta-ray dose backscatter factors with respect to soft tissue were measured using an extrapolation chamber. The beta-ray dose backscatter factor is a measure of the change effected in absorbed dose to a soft-tissue medium when part of the medium is replaced by a material other than soft tissue (i.e., a scatterer); the source is located at the boundary between the two media. The dependencies of backscatter factor on scatterer atomic number and …
