Monitoring a Flow of “Hot” Tritium Atoms in the Course of Thermal Activation

Abstract

The possibility of measuring a flow of reactive tritium atoms falling on a target during thermal activation using polyethylene (PE) films was studied. Procedures were developed for pretreatment of PE films before experiment, their subsequent treatment, and radioactivity measurements. The distribution of the flow of tritium atoms in a common reactor as influenced by various modes of atomizer arrangement and different experimental conditions was studied with PE films. The rate of formation of the labeled compound was maximal when the product of the tritium pressure in the system (Pa) by the distance from the atomizer to the target (cm) was 2.
