| Abstract: | A internal gas proportional counting system for absolute measurement of gas radioactivity was established. The performances of the system, such as plateaus, background, deadtime, end effect and wall effect were well tested. Then the activity concentration of 87Kr was measured absolutely to be 40.64（1±0.9％） Bq/mL by this equipment. |
