Polymer Radiation Dosimeter (POLYRAD)

This proposal addresses the need for a new generation of low-cost self-indicating casualty dosimeter. The application involved is determination of personnel dose exposure during a nuclear conflict. The major specifications for this dosimeter include: (1) a minimum sensitivity range of 50-1500 R, (2) simple dosage indication without the aid of external devices, (3) long-term (20 yrs) storage stability, and (4) low cost (less than $2 per dosimeter). Spectral Sciences, Inc. (SSI) proposes to develop the P0LYmer RAdiation Dosimeter (POLYRAD) which has the potential to meet or exceed these target polymerization chemistry. The primary goal of the Phase I effort is an experimental proof-of-concept demonstration of the approach. The specific objectives include: (1) initial screening of several candidate polymer systems, (2) characterization of the radiation dose dependence of the polymerization chemistry, and (3) preliminary design of the Phase II brassboard P0LYRAD device. In Phase II prototype P0LYRAD dosimeters would be constructed, tested, and calibrated.
