An automatic conveyor-type laundry monitoring system, which monitors laboratory coats and coveralls simultaneously for both alpha and beta-gamma contamination, was developed to improve efficiency and monitoring control. The instrument employs eight alpha and seven beta-gamma scintillation large-area detectors, a garment conveyor, solid state circuitry, and appropriate signalling devices. In operation, garments are physically placed on hangers which are then placed onto the automatic loader. Each garment is then conveyed past the detectors where it is monitored for beta-gamma and alpha contamination. Contaminated garments are rejected and dropped into a special container if spot contamination exceeds 1000 d/m of alpha or 5000 d/m of mixed fission products. The acceptable garments pass through the system for folding and distribution. The system, which requires only one attendant, can effectively monitor 500 garments per standard shift. System operation has been fully successful for five months. (auth) size, as the Te/sup 132/. Uranium was found to be present in the effluent in particulate form, but it was not possible to tell whether it was there independently or in conjunction with the iodine or tellurium. (auth)
