Research Capabilities

Radiation Physics, Dosimetry, and Shield Design

PNNL staff are experienced at modeling radiation detection devices, calibration facilities, radiation sources, and spent-fuel storage casks. We also use male and female anthropomorphic "phantom" models to evaluate the effective dose and dose equivalent to individual organs for workplace, environmental and accidental radiation exposures. We have evaluated other radiological protection quantities based on the latest International Commission on Radiological Protection and International Committee on Radiation Units and Measurements guidance. Advanced visualization techniques are used to document model geometries; illustrate radiation streaming through filters, shields and duct work; and show dose contours around hot spots and sources.
