Summary:As part of the continuing DOE effort to upgrade personnel neutron dosimetry, the Health Division at Los Alamos has developed a portable, battery-operated, computerized neutron spectrometer/dosimeter. The instrument has a built-in tissue-equivalent LET neutron detector, 128-channel pulse height analyzer with integral liquid crystal display, and a microcomputer system which calculates dose and dose rate from neutrons incident on the detector. The neutron spectrometer/dosimeter is designed around a linear energy transfer (LET) proportional counter. The instrument will, at the user's option, display a raw data spectrum or a spectrum of rad or rem as a function of keV per micron of equivalent tissue. The dosimeter will also calculate and display accumulated dose in millirad and millirem, as well as giving the user neutron dose rates in millirad and millirem per hour.
