The relative gas gain, alpha particle resolution and gain stability of two A150-plastic equivalent gas mixtures (A150 Mix-1 and A150 Mix-5) as well as propane and methane based tissue equivalent mixtures were measured with a spherical A150-plastic-walled proportional counter. The event-size distribution in a 14.8-MeV neutron field was determined for each gas mixture. Absolute tissue doses deduced from these measurements were in substantial (1%) agreement with doses determined by a TE-plastic ionization chamber and miniature GM counter.
