A technique for measuring the D(.07) and D(10) dose rates in mixed beta/gamma radiation fields through the use of a tissue equivalent detector and portable multichannel analyzer has been developed and field tested. Two energy spectra are collected for each measurement, an open window spectrum representing the tissue response to betas plus photons, and a second filtered spectrum representing the photon response. A close approximation to the net beta spectrum is obtained by spectrum stripping, and the D(.07) dose rate is calculated by multiplying channel by channel by a beta energy deposition function. Computer plots of typical field spectra and dose rate calculations are presented. 3 refs., 17 figs.
