Concentration of natural and artificial airborne activities near ground level at Winnipeg

· Canadian Journal of Physics
Concentrations of radon, thoron, and particulate failout are evaluated on a day-to-day basis from December 1958 to May 1962, especially for the period subsequent to the Russian tests in the fall of 1961. The efficiency of the filter used for the collection of aerosols carrying active deposits of radium and thorium is determined as 98.2 plus or minus 0.8%. The magnitude and extent of the corrections applied to the data are discussed in detail and the results for the fallout concentration at Winnipeg are analyzed. The decay of fresh fallout is followed for periods up to two months and a correlation between the date of explosion and the occurrence of a peak in the failout concentration is indicated.
