radioactive tracer technique

in analysis
A technique for investigating @R05206@ and loss of a microcomponent, in which a radioactively-labelled element or compound chemically identical with the microcomponent is added to the sample before @P04803@ and its behaviour is followed by sensitive, rapid and selective @R05092@ measurements.
