Claims (3)

1. Способ утилизации металлических частей, радиактивно загрязненных радиоактивными элементами, в частности источниками α-излучения, причем из металлических частей образуют расплав и шлак и шлак затем отделяют от расплава, отличающийся тем, что перед образованием расплава и шлака радиоактивные элементы окисляют и для окисления радиоактивных элементов радиоактивно загрязненные металлические части выдерживают в течение некоторого промежутка времени при температуре ниже температуры плавления металлических частей в атмосфере, содержащей кислород.1. The method of disposal of metal parts that are radioactively contaminated with radioactive elements, in particular sources of α-radiation, moreover, the melt and slag are formed from the metal parts and the slag is then separated from the melt, characterized in that before the formation of the melt and slag, the radioactive elements are also oxidized to oxidize the radioactive elements radioactive contaminated metal parts can withstand for a certain period of time at a temperature below the melting point of metal parts in the atmosphere, containing th oxygen. 2. Способ по п.1, отличающийся тем, что содержащая кислород атмосфера является сухим или влажным воздухом. 2. The method according to claim 1, characterized in that the oxygen-containing atmosphere is dry or moist air. 3. Способ по п.1 или 2, отличающийся тем, что промежуток времени составляет 10 - 60 мин. 3. The method according to claim 1 or 2, characterized in that the period of time is 10 to 60 minutes
