【美国《核新闻》1983年3期第106页报道】加拿大的阿尔法核仪器公司同堪梅特(CANMET)公司合作研制成的750型Rn/Tn 监测器,在空气中放射性核素取样和分析方面采用了经过改进的技术。这种计算机化的仪器使甩了一个流量可调的泵,通过连续运动的过滤纸带提取空气中的微粒样品。过滤器按照可编程序的时间间隔向前移动,因此可以进行半连续的取样和分析,适合短时间的应用和可提供放射性强度趋势记
【US Nuclear News, 1983, No 3, page 106】 Radionuclide sampling and analysis in air was performed on a 750 Rn / Tn monitor developed by CANADA in collaboration with CANMET Canada. In terms of the use of improved technology. This computerized instrument dumped a flow-adjustable pump to extract airborne particulate samples from a continuously moving filter paper. Filters are moved forward at programmable intervals so that they can be semi-continuously sampled and analyzed for a short period of time and provide a trend of radiometric intensities
