Dennis, J A; Loosemore, W R

A fast neutron counter, consisting of a series of polyethylene-lived cells with a common anode wire and filled with a mixture of Ar and CH/sub 4/, is considered. The counting rate of the proton-recoil proportional counter is directly proportional to the estimated biological dose due to fast neutrons in the range 0.1 to 15.0 Mev so that the counting rate is 0.9 hr at 1500 deg 0.18 c sec/sup -1/ per maximum permissible level of fast neutron flux. The minimum pulse size at the counter anode with an applied potential of 1400 v corresponded to the collection of 5.5 hr at 1500 deg 2.5 x 10/sup 6/ ion pairs. (C.J.G.)
