In mesuerment of tritium by the proportional counter,methane is usually used as counter gas.Gas samples have been made with helium and methane in the proportion of concentration and measured to sdudy the influence of helium on the counter's measurement properties.Then gas sample with tritium and helium has been measured,and the result is according with anticipation.The experiment has showed that the plateau curve of counter could be changed by helium,but the influence could be ignored when helium concentration less 10%.
