摘要
在地下洞库、坑道或地下核设施,尤其是处在花岗岩地带的地下设施,其环境中的氡及其子体产物的浓度可高达103-104Bq/m3,它们将严重干扰人工核素(例如U、Pu)气溶胶的监测,甚至会造成测量失效,这是多年来急待解决的问题。为此,研制了一种新型气溶胶监测装置。该装置适用于在花岗岩坑道内氡水平较高的环境中测量低水平的铀、钚气溶胶浓度,并具有灵敏高、探测速度快的优点。该监测装置也可用于核设施工作场所及气态排出流中气溶胶的快速连续监测。
The aerosol concentration of radon and its daughter is high to 10^3-10^4 Bq/m^3 under hole base, sap and especially nuclear equipment environments, it will affect the detection of human nuclide aerosol （ for example U, Pu ）, even result in measure invalidation, which is a urgent problem to solve for many years. Now, we have researched and manufactured a new equipment for detect aerosol concentration. It can be used to detect human nuclide in high Radon aerosol concentration. , And it also has a high sensitivity and a rapid detection velocity. This equipment can detect aerosol concentration rapidly and continuously in nuclear work location and gas vent.
