Abstract : The concentrations of radioactivity in the air in Alaska are documented from data collected by NRL air-monitor equipment operated at Kodiak (1950-1960) and Wales (1953-1959). Seasonal variations in the short-lived natural radioactive components of the air are observed at both sites while variations in the fission product concentration are directly related to periods of nuclear testing, particularly by the Soviet Union. Concentrations of both natural and fission product activities are generally much lower than those found along the eastern seaboard of the United States. The possible use of thorium B as a tracer for short-term atmospheric processes is pointed out. (Author)
