ANALYSIS OF HIGH-ALTITUDE FILTER AND IMPACTOR MEDIA FOR EVALUATION OF PROPOSED SNAP REENTRY EXPERIMENT USING NONRADIOACTIVE TRACER.
Abstract
This study was initiated to evaluate the feasibility of using simulator elements as tracers to determine the potential hazard involved in atmospheric reentry of SNAP devices. The sensitivity of such a simulator experiment is determined in part by the backgrounds of the atmosphere and the collection media. Several materials selected as representative high-purity filter media and impactor substrates were analyzed by neutron activation analysis followed by radiochemical separations. These materials included IPC Grade 107, cotton base paper, Microsorban, Suprasil high-purity quartz, collodion, and silicone oil. Analysis of special flown filter samples determined that uranium was present in the atmosphere, but no other elements were detected above media background. The two most suitable tracers based on least amounts found in all collection media studied are thulium and rhenium.
