The threat of a Radiological Dispersal Device (RDD) detonation arouses the
concern of contaminated victims of all ages. The purpose of this study was to
investigate the dose to a uniformly contaminated five-year old male. It also explores the
exposure rates surrounding the victim to be used by first receivers to estimate their
exposure from the victim.
The victim was modeled as an anthropomorphic phantom using the BodyBuilder
program. A thin layer of source material was added to the surface of the phantom’s skin
to simulate whole-body contamination. The computer code MCNP5 was used to tally
the doses to the individual organs of the phantom and create a mesh to generate contour
exposure rate lines.
Using an activity of 37 GBq m-2, the five-year-old victim received an effective
dose 158.23 mSv in one hour. Contour lines were produced that showed the exposure
rates around the victims ranging from 0.5 to 10 R/h. The contour exposure-rate contour
lines were also generated after the removal of contaminated clothing. Removing the
victim’s clothing reduced the exposure rates by eighty percent.
