Abstract:

Aerosol radioactivity analysis plays an important role in environmental radiation monitoring. The set up of CNP22 in Guangzhou, China allows station operators to log in a continuous radioactivity data and find radioactivity characteristics. The concentrations of Pb-210 and Be-7 give seasonal variation and show a maximum in winter times. A relationship between Pb-210, Be-7 and PM10, PM2.5 were analyzed.
