A DOSE MONITORING INSTRUMENT FOR NEUTRONS FROM THERMAL TO 100 Mev

Scientific Laboratory the observed overestimate of the total dose rate varies up to a maximum of 65 per cent. The use of this instrument to monitor neutron fluxes of unknown energy and spectrum gives an indicated dose rate that is ordinarily much more accurate than that obtained with thermal and fast neutron monitoring instruments presently in use at Los Alamos. In circumstances where the scattered or intermediate energy neutrons contribute significantly to the total dose, this instrument is the only one known by the author which with reasonable accuracy detects and evaluates the dose rate with no assumptions or calculations required.
