In order to determine the emission rate of the large-area source that active area is up to 1 000 cm2,a suit of non-window type large-area 2πmulti-wire proportional counter was established.Thecharacteristics of the whole system were tested using both point source with active diameter of 8 mm and large-area source with active size of 10 cm×15 cm.The results show that the effective detective area is up
