The effects which SiF/sub 4/, SO/sub 2/, and SF/sub 6/ have on the plateau and the pulse size distribution of a proportional counter were investigated. SiF/sub 4/ was tested at three pressures, 30, 45, and 60 cm, of BF/ sub 3/ and its effect was found to be independent of the counter pressure for the range of value considered. From the variation in the plateau, the attachment probability for SiF/sub 4/ was calculated to be h= 1.485 x 10/sup -5/ and its cross section for attachment to be sigma /sub a/ = 5.12 x 10/sup -20/ cm/sup 2/. The amount of these gasea permitted, without the counter being affected beyond the limits of tolerance which are set up, were found to be 0.04% for SiF/sub 4/, 0.01% for SO/sub 2/, and 2.0 x 10/sup -6/% for SF/sub 6/.
