Anisotropic Dose and Its Applications in Directional Radiation Sensing,

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.
