Model 2363 with 42-41L

This gamma/neutron survey meter combines Ludlum Model 2363 survey meter with the Model 42-41L PRESCILA neutron detector. The gamma detector is an energy compensated GM housed internally to the survey meter. The neutron detector is a proton recoil type, which provides excellent measurement results at less weight than the more traditional REM balls. The neutron measurement has excellent gamma rejection up to 100 mR/hr.
