PURPOSE:To decrease a collective exposed dose, by keeping a distance from a solidified body by remote operation and shortening the exposed time by automating the measurement. CONSTITUTION:A receptacle of radioactive waste matter 1 is carried on a weight measuring apparatus 2 by a crane and the weight is measured and then, specific gravity of packing is assumed. Next, the receptacle 1 is placed on a transfer truck and a surface pollution level is examined by a smear test by a surface pollusion level measuring apparatus 3. Then, the receptacle 1 is transferred to a dose rate measuring apparatus 4 after confirming that the surface pollusion of the receptacle 1 is not recognized and the surface dose rate and 1m dose rate, are measured. Further, the receptacle 1 is transferred to a packing nuclear seed measuring apparatus 5 successively and the radioactive quantity classified by a nuclear seed which is packed per one receptacle 1, is found. The result measured by each measuring is synthesized by a digital computer 7 and a prescribed judgment is made and then, a prescribed control signal is outputted to a display apparatus. |
