The machine is designed to check working clothes after decontamination treatment. It checks automatically for alpha and beta - gamma . The clothing is carried on a moving belt under a rack of Geiger-Muller counters followed by zinc sulfide scintillators linked to photomultipliers. During its passage under these probes two separate counting systems count the beta - gamma and the alpha activities. If a certain fixed rate is reached, a basket reserved for contaminated linen moves into position in front of the belt to collect the clothing; if this rate is not attained the linen is collected in another basket. The starting and stopping of eounting, and the return to zero, are controlled by means of 3 photoelectric cells which detect the arrival of the clothing before and after scanning, and its delivery into the baskets.
