A transistor alpha hand monitor device and a portable kicksorter are described. The new hand monitor employing scintillation fluors on light pipes is more sensitive, is less than 1/3 as large, costs less, and is less exspensive to maintain than the Four-Fold instrument it replaces. The scintillator system, circuits, controls, operation, and calibration are described. The portable kicksorter weighs 7 lb, has a battery life of 250 hours, and spans energies from 0.1 to 1.5 Mev with 10 turns of a dial, with simple adjustment to an upper limit at 2.0 Mev. The minimum stable window width is 10 to 20 key giving a system resolution with Cs/sup 137/ of 13.4%. (T.R.H.)
