註釋
The feasibility of detecting small quantities of toxic propellants in the atmosphere by utilizing the decay characteristics of radioactive materials was studied. Activation analysis and inverse radioactive tracer techniques were used. The latter may be defined as processes in which a constituent to be analyzed undergoes a reaction (or reactions) which results in the ultimate release of a radioactive tracer gas whose concentration is proportional to the original constituent to be analyzed. Five toxic materials were selected for investigation; they included nitrogen dioxide, hydrazine, unsymmetrical dimethyl hydrazine, boron hydrides, and beryllium oxide. Emphasis was placed upon the use of Kr85 quinol clathrates for the detection systems. Properly controlled, these systems were found to be selective to a narrow band of redox materials and gave predictable responses to toxic gas concentrations.
