Abstract
In order to measure the level of radioactivity of liquids in a set of vessels, e.g. those employed in a competitive radio-assay, liquid is drawn successively from each one of the set into a measuring region defined inter alia by radiation shielding, so as to fill the region, the measurement takes place in the region, and the liquid is thereafter expelled.
