Progress report on the determination of alpha emitters in air /

An electrostatic precipitator and a newly developed filter paper are compared for efficiency, reliability, availability, and ease of use. The aerosols collected in either case are counted for alpha activity in a cylindrical pulse chamber, the design of which is an adaptation of the breech-locking air alpha chamber. Vapor and gases are not collected by either instrument, unless occluded on particulate matter.Work performed at the Argonne National Laboratory."Date Declassified: August 2, 1948.""AECD-2191."Title from cover.Includes bibliographical references (p. 4).An electrostatic precipitator and a newly developed filter paper are compared for efficiency, reliability, availability, and ease of use.
