Abstract
Abstract The determination of trace amounts of thallium by the thermal neutron reaction 203Tl(n,γ)204Tl is complicated because 204Tl is a pure β-emitter, requiring a lengthy and rigorous separation. In addition the half-life of 204Tl is too long to permit decay measurements. A photon activation analysis method has been developed for this determination. Bremsstrahlung from a beam of 35-MeV electrons induces the photonuclear reaction 203Tl(γ,n)202Tl. The detection limit is of the nanogram order. There are no interfering photonuclear reactions from lead.
