When exposed to a source of ionizing radiation of doses ranging from 10/ sup 6/ to 10/sup 10/ ergs/g carbon, nitrous oxide decomposes linearly as a function of the absorbed dose in the ratio N/sub 2/: O/sub 2/: NO/sub 2/: 1.0: 0.14; 0.48 as stable products. With the addition of a small amount of U/sup 235/ to the dosimeter, the gas can be used in neutron dosimetry. The principle of Hartech and Dondes was utilized in the development of nitrous oxide in the dosimetry program associated with the Lockheed Radiation Effects Reactor (RER). This has included the design of practical dosimeters and vacuum analytical apparatus, equipment calibration, and the development of a routine method. Although the reactor exposure data produced a similar curve to that of the pure gamma data, there are definite indications of the neutron effect in the decomposition values of the gas bias the gamma dose. However, the expected break in the decomposition curve is obtained at the equivalent dose of 10/sup 11/ ergs/g carbon. The advantages of nitrous oxide as a total-dose dosimeter include post-irradiation stability, flexibility, and economy. It is adaptable to a variety of uses, including high-flux material testing and total-dose monitoring in areas of high radiation exposure.
