The invention relates to a quartz internal gas proportional counter. The proportional counter comprises a cathode sleeve and an anode wire arranged at the axis of the cathode sleeve. A working gas anda mixing gas of a radioactive gas to be measured are filled in the cathode sleeve. The beneficial effects of the invention are as follows: 1, a quartz tube is adopted as a wall of a cathode tube, theinner wall is lined with a conductive metal layer, so that the background can be effectively reduced; 2, a quartz tube is adopted as the wall of the proportional counter, and an insulator structure does not need to be additionally added at two ends of the quartz tube; 3, a quartz glass tube is adopted as a main material, the process is mature, the quartz glass tube can be manufactured in batches,so that the cost can be effectively reduced. The tedious decontamination for measuring a sample, such as 3H, of a contamination detector is omitted. 本发明涉及种石英内充气正比计数管，包括阴极筒和设置于所述阴极筒轴线位置的阳极丝；所述阴极筒内充有工作气体和待测量放射性气体的混合气体。本发明的有益效果如下
