A kinetic model of the active medium is developed for a nuclear-pumped laser (with an He - Cd - CCl{sub 4} mixture) based on transitions in the cadmium ion and atom. The results of numerical modelling give the distribution of the relaxation flux between excited states of the cadmium atom. A study is reported of the mechanisms responsible for the influence of the addition of carbon tetrachloride on the evolution of relaxation processes in an He - Cd plasma and on stimulated emission of the {lambda} = 325.0 nm line. It is shown that the main factor hindering lasing as a result of the 4d{sup 9} 5s{sup 2} {sup 2}D{sub 3/2} {yields} 4d{sup 10} 5p {sup 2}P{sub 1/2} transition is the parasitic absorption of the stimulated radiation by metastable cadmium atoms.
