FIELD: chemistry. ^ SUBSTANCE: method of automatic sorting of soils contaminated with radioactive nuclides lies in the following: fine classes of soil with coarseness less than 20-30 mm, are supplied onto separator belt in form of continuous flow, which together with belt passes through two successively placed combined measurement units, each of which simultaneously and separately registers gamma- and beta- radiation. Signal from measurement unit goes to separating two-step mechanism. Device for method realisation consists of set of sieves for sising initial material, unit of soil reception, feeder, supplying soli onto belt of sorting machine and separating mechanism. Sorting machine represents frame with rotating drums, on which 2-4 thin and narrow autonomous belts with flanges are pulled on, along each two also autonomous combined measurement units are located, each of which consists of unit of beta-radiation detectors, located above sorting machine belt and unit of gamma-radiation detectors, located under belt, central vertical axes of both units coincide. Near front belt end two-step separating mechanism is located. ^ EFFECT: invention allows sorting soils with small portion weights. ^ 4 cl, 2 dwg, 1 tbl |
