Atmospheric 222Rn Measurements at San Nicolas Island During 1980.
Abstract
The results of radon concentration measurements in the near surface air at San Nicolas Island, California, are presented for five different measurement sessions between May 1978 and July 1980. Emphasis is on the previously unreported results for January and July 1980. For six of eight days during the January session the measured radon concentration was greater than 40 picocuries per cm, corresponding to a continental air mass. Only the first day involved a maritime air mass with radon concentration less than about 6 picocuries per cm. In contrast to all the previous sessions, maritime air dominated the ten day session in July 1980, with radon concentrations generally less than about 5 picocuries per cm.
