Sampling air for the presence of nuclides

摘要: Equipment for sampling gases, partic. air, to detect the presence of nuclides, by stepwise separation through two in-line filters. The installation consists filters (9, 10) in filter rings (7, 8) seated openings (5, 6) discs (1, 2) which are rigidly connected coaxially parallel planes shaft (3). Upper (5) and all associated fittings larger than lower opening (6) its fittings. line so that pushrod (13) with is ring head (11) can assemble a set carry them though (17) casing (12) collect sample. This done pump (160 sucking air hollow rod (13). A sensor (15), radiation sensor, placed after position, disc assembly being rotated stepping drive (4). Pushrod moved linearly (14). Also claimed procedure.
