Description/Abstract The response of sapphire (Al/sub 2/O/sub 3/) thermocurrent (TC) dosimeters to 14 MeV neutrons is about 10% of the response to cesium gamma rays on an equivalent tissue rad basis.^The addition of proton radiator covers of methyl methacrylate increases this response to about 15%.^The magnitude of the thermocurrent peak at 260/sup 0/ (peak 3) allows measurement of gamma ray exposures of 10 mR with a signal to noise ratio of about unity.
