A Low Cost Self Indicating Radiation Dosimeter

1In order to replace the DT-60/PD dosimeter system, the Navy needs a casualty dosimeter which can be used to determine personnel dose exposure (50-1,000 rads) during potential nuclear conflict. The dosimeter should cost less than $2, should have shelf-life of 20 years and can be read without an equipment. A unique class of compositions will be used to prepare the dosimeter. The dosimeter will develop color when irradiated when irradiated with 20 - 5,000 rads of gamma rays. The color intensity will be proportional to the dose. The dose can be estimated with better than 20% accuracy using a calibrated reference color chart. The dosimeter will be having shelf-life of more than 20 years. The cost will be less than $2 per dosimeter.
