Measuring arrangement for determining the concentration of gaseous radioiodine in a carrier gas, composed of a mass of sorption agent for separating the gaseous radioiodine from the carrier gas and for accumulating the separated radioiodine, with a part of the mass of sorption agent being located in a measuring region, a conduit for conducting the carrier gas to the sorption agent and provided with at least one outlet via which carrier gas can flow into the measuring region containing sorption agent, and a radiation detector disposed for detecting radiation emanating from the measuring region, with the sorption agent being movable relative to the conduit for bringing different portions of the mass of sorption material into the measuring region. |
