Summary
Because the use of filters to sample panticulate matter suspended in the upper atinosphere has been investigated and has yielded rather disappointing results, an examination of other methods of upper atinospheric sampling is desirable, and this is the aim of the present study. The rature of any radioactive material and its relation to the size and composition of the suspended particles are of particular interest. Among the methods considered are those based on electrical, mechanical, and thermal separation processes. under conditions of relatively long molecular mean-free-path in the suspending air. With reasorable restrictions of weight and time of collection. success may be expected using sufficiently refined designs based on each of these methods. Certain advantages and disadvantages are associated with each, as might be expected. but the greatest possibility of success appears to be offered by a centrifuge designed carefully to maintain laminar flow.
