Relation of Radon to Non-active Air Contamination

Abstract

Anderson, Mayneord and Turner¹ have directed attention to the variation of atmospheric radon content. It may be of interest to note that similar observations were made here during the four months, November–February, 1953–54. Samples were collected daily from air drawn through four-inch filter paper TFA-41. The activity of the papers was determined by inserting them directly into an ionization chamber with a vibrating-reed type amplifier and an inked pen recorder. A second set of observations was obtained by the more laborious counting of beta-emission with a mica window counter.
