• A special type of proportional counter has been constructed in which the source can be placed internally with provision for its covering and uncovering by an absorber, without disturbing the pressure inside the counter. Using this counter, the variation of the escape probability f_K of argon KX-rays with pressure was estimated. The intensity ratio I(KX-rays)/I(14.4 keV γ-rays) for a Co^<57> source at five different pressures was also determined and compared with the theoretical value. The Constancy of this ratio at these pressures supports the reliability of experiment.
