METHOD OF CHEMICALLY DEACTIVATING SURFACES OF METALLIC OBJECTS CONTAMINATED WITH RADIOACTIVE MATERIALS |
| 摘要 |
FIELD: radiation protection. SUBSTANCE: surfaces of metallic (steel, nonferrous metals, their alloys) objects are treated for 1 to 24 h at 20 to 95 C with aqueous deactivating solution containing carboxylic acids constituting caprolactam production acidic waste. Invention enables efficient one- step deactivation of various metals including those with surface corrosion products of paint-varnish coatings with relatively small volume of exhaust solution. EFFECT: increased deactivation efficiency and reduced expenses. 4 cl, 4 tbl
