【摘要】 根据氡子体与人工放射性气溶胶粒径的差异,研制了一套氡子体粒度分离采样器。这种装置能在采样过程中分离掉氡子体,主要采集关注的人工放射性气溶胶。使用这种采样器进行采样,可显著降低氡子体的干扰,提高监测灵敏度。该采样器经过改造,也可用于放射性气溶胶连续监测仪。更多还原

【Abstract】 Based on size distribution difference of radon progeny and artificial radioactive aerosols,a radon progeny separation sampler was developed. This device can separate most radon progeny in the sample process,and mainly collect artificial aerosols. If this device is used to collect aerosols,interference due to radon progeny can be significantly reduced,and monitoring sensitivity can be increased. If appropriate improvement was made, this sampler can be used in continuous radioactive aerosol monitor.更多还原
