Abstrakt:	Tests of how effectively CH I and radioactive iodine are removed from air for the ventillation system of the VVRts reactor are performed. Carbon-fiber materials such as Busofite and fiber materials filled with impregnated OU-A carbon are studied as sorbtion-filtering materials. It is shown that these materials absorb iodine with approximately the same efficiency. The front layer traps I2. CH3I becomes distributed on several layers of the sorbing assembly. Iodine desorption from Busofite and the fiber material with OU-A is negligible (≤2%) over 114–3000 h. Recommendations are given for the composition of the fiber materials for removing iodine from air. [ABSTRACT FROM AUTHOR]
