An automatic conveyor-type laundry monitoring system, whlch monitors laboratory coats and coveralls for both alpha and beta-gamma contamination, was developed and installed at the Hanford Laundry Facility to improve monitoring efficiency and control. The instrument employs eight alpha and seven beta-gamma scintillation large-area detectors, a garment conveyor, solid state circuitry, and appropriate signaling devices. Oarments are manually placed on hangers which are then placed onto an automatic loading mechanism. Each garment is conveyed past detectors where it is monitored for beta-gamma and alpha contamination. Contaminated garments are rejected and dropped into a special contniner if spot contamination exceeds 1000 disintegrations per minute (dis/min) of alpha or 5000 dis/min of mixed fission products. The garments which are not rejected pass through for folding and distribution. The system, which requires only one attendant, can effectively monitor 500 garments per standard shift. System operation was fully successful for ten months. (auth)
