Title: Detector Photon Response and Absorbed Dose and Their Applications to Rapid Triage Techniques
Author: Voss, Shannon Prentice
Abstract: As radiation specialists , one of our primary objectives in the Navy is protecting people and the environment from the effects of ionizing and non -ionizing radiation . Focusing on radiological dispersal devices (RDD ) will provide increased personnel protection as well as optimize emergency response assets for the general public . An attack involving an RDD has been of particular concern because it is intended to spread contamination over a wide area and cause massive panic within the general population . A rapid method of triage will be necessary to segregate the unexposed and slightly exposed from those needing immediate medical treatment . Because of the aerosol dispersal of the radioactive material , inhalation of the radioactive material may be the primary exposure route . The primary radionuclides likely to be used in a RDD attack are Co -60 , Cs -137 , Ir -192 , Sr -90 and Am -241 . Through the use of a MAX phantom along with a few Simulink MATLAB programs , a good anthropomorphic phantom was created for use in MCNPX simulations that would provide organ doses from internally deposited radionuclides . Ludlum model 44 -9 and 44 -2 detectors were used to verify the simulated dose from the MCNPX code . Based on the results , acute dose rate limits were developed for emergency response personnel that would assist in patient triage .
