Résumé du livre
A survey of the physical properties and operational characteristics has been made of the FPP-15 filter paper widely used in the Soviet Union for monitoring airborne radioactivity. This filter material is composed of a thin mat of small-diameter, unoriented fibers of polyvinyl chloride deposited on a cotton scrim backing. Due to its composition, the filter readily picks up an electrostatic charge which causes some difficulty in handling but which contributes to an increased initial retentivity toward submicron aerosol particles. Functionally, the filter combines low resistance to air flow with good retentivity toward fission-product aerosols. (Author).
