29 Testing of iodine filters in nuclear power stations Iodine filters in nuclear power stations reduce the environmental exposure of radioactive gases released with the gaseous effluents of nuclear power stations The sorbents, which are used for iodine filtration, are tested in laboratory for removal efficiency using mostly worst case working conditions The removal efficiency which can be achieved by an iodine filter depends on the quality of the sorbent, the relevant operating conditions, and on the leaktightness of the filter.
