Beta-particle backscatter factors and energy-absorption scaling factors for use with dose-point kernels

Creator:

Mangini, Colby D.

Abstract:

'Hot particle' skin dosimetry calculations are commonly performed using homogeneous dose-point kernels (DPK) in conjunction with scaling and backscatter models to account for non-homogeneous geometries. A new scaling model for determining the actual DPK for beta-particles transmitted by a high-Z source material has been developed. The model is based on...

A beta dosimeter and spectrometer utilizing plastic scintillators and a large-area avalanche photodiode

Creator:

Kriss, Aaron A.

Abstract:

The purpose of this research was to develop and test a radiation detector to perform beta dosimetry and spectroscopy. The detector utilizes plastic scintillator volumes to produce scintillation light in proportion to the amount of energy deposited in them, and a large-area avalanche photodiode to convert the light to electrical...
