In the summers of 1990 and 1991, outdoor 222Rn detectors were installed for 3 mo in 78 communities across Canada. The 1990 measurements showed large regional variations with the average outdoor levels for the provinces of Manitoba (59 Bq m-3) and Saskatchewan (61 Bq m-3) exceeding the average indoor levels of 55 Bq m-3 for the U.S. The variations in the 1990 222Rn levels showed little correlation with the uranium concentration of the ground and were attributed to changes in soil moisture… CONTINUE READING
