A novel concept is proposed for the development of a personnel dosimeter for ionizing radiation, such as, gamma ray. the dosimeter uses a specialty class of radiation sensitive conductive polymeric compositions. when exposed to low dosage of ionizing radiation, the polymeric compositions would… More

A novel concept is proposed for the synthesis of intrinsically conductive polymers. the conductive polymers ppolydiacetylenes will be synthesized by the solid-state polymerization of diacetylenes polarizable groups, either upon thermal annealing or upon exposure to high-energy radiation. the… More

Chromic acid is used for etching plastics for electroplatingand electromagnetic interference (emi) shielding. more than a million pounds of chromic acid is used every year in the united states of america for etching plastics. hexavalent chromium is highly toxic. requires expensive equipment for its… More

In order to protect the consumer, it is important to deter mine the shelf-life of perishables and monitor it. the devices available commercially are expensive, bulky, and do not mimic the deterioration of perishables. an ideal device for monitoring residual shelf-life of perishable is proposed. the… More

Houses in several states have high concentrations of radon. radon and its daughters can cause cancer, as they emit aplhaparticles. there is an urgent need for a device for monitoring radon. a novel device for monitoring very low concentrations of radon and its daughters is proposed in this project.… More

There is a need for radioagraphic film for high-energy x- rays that can provide high contrast between different tissues, such as normal tissues and tumor. a novel concept is proposed for development of such film. compositions thatare highly sensitive to high-energy radiation are proposed for the… More

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… More

A novel class of compounds and processes are proposed for radiation dosimetry and imaging devices. The formulations and processes will be optimized. Prototype devices, such as films, plaques and blocks will be prepared. The films will be evaluated as diagnostic imaging films, the plaques will be… More
