The initial yield of nitrogen from nitrous oxide (1 atm, 20 deg C) irradiated with Co/sup 60/ gamma rays was G/sub N2/ = 12.8 plus or minus 0.4 molecules per 100 ev. The energy absorption was determined by ionization current measurements. Determination of the energy absorbed by the Fricke dosimeter gave G/sub N2/ = 12.0 plus or minus 0.4. The initial G/sub N2/ was independent of the pressure of N/sub 2/O between 200 and 760 mm Hg and of dose rate between 0.73 and 3.0 x 10/sup 14/ ev ml/sup -1/ min/sup -1/. G/sub N2/ was not independent of tot al dose but decreased at doses greater than about 2.4 x 10/sup 17/ ev ml/sup - 1/, having a value of 9.3 at 2.5 x 10/sup 18/ ev ml/sup -1/. The yields of nitrite, formed when the irradiated gas was extracted with sodium hydroxide solution, and of oxygen were determined. (auth)
