【摘要】 大气颗粒物采样器是《全面禁止核试验条约》中放射性核素监测的关键设备。作为条约规定的职能之一,放射性核素实验室应具备大气放射性颗粒物样品的采集和分析能力,因此所安装的采样器应满足条约对国际监测系统中大气颗粒物采样器的相关要求。结合实验室实际情况,成功研制了 PMS-800大气颗粒物采样器。该采样器具有稳流采样功能,在颗粒物浓度较大时可以延长采样时间。测试表明,PMS-800大气颗粒物采样器最大流量达800m~3/h 以上,流量不确定度小于5%,自采样开始每10分钟存储一次系统参数,满足临时技术秘书处对国际监测系统大气颗粒物采样器的要求。更多还原

【Abstract】 Air particulate sampler is an important equipment for CTBT radionuclide monitoring.The radionuclide laboratory must have a capability of sampling and analyzing air radioactive particulate sample that is one of function provided by CTBT.So,the property of the perticulate sampler set up in the radionuclide laboratory should be according to the request of CTBT.PMS-800 air particulate sampler was developed according to the condition of the radionuclide laboratory.The sampler can prolong the sampling time when the concentration of particulate is high because it can stabilize the flow-rate.The performance of the sampler was valuated,and the results showed it accorded with the request of CTBT.The biggest flow-rate of the sampler was above 800m~3/h,and the certainty of the flow-rate was less than 5%,and it can save the system parameters every 10-minute.更多还原
