Abstract:
While conducting radiation experiments using polyvinyl chloride and photographic film as dosimeters the author noticed anomalous hot spots in dose delivered to regions where there was a perturbation in the atomic number Z close to the dosimeter. These increases in local dose were strongly dependent on the direction of the incident radiation and could be observed even when the perturbation was a very thin layer of different Z material. Such perturbations can affect measurements of gamma and X-ray doses and may be responsible for serious errors in dosimetry if one is not aware of their existence. This effect is discussed in the report.
