Title:     Monitoring 131I in rainwater and seaweed in British Columbia following the Fukushima accident

Abstract: Detailed analysis of 131I levels in rainwater and three species of seaweed (Fucus distichus Linnaeus, Macrocystis pyrifera, and Pyropia fallax) collected along the southwestern and central coast of British Columbia, Canada was performed using gamma-ray spectroscopy following the Fukushima nuclear power plant accident on March 11, 2011. Maximum 131I activity was found to be 5.8(7) Bq/L in rainwater collected at the campus of Simon Fraser University (SFU) in Burnaby, BC nine days after the accident. Concomitantly, maximum observed activity in the brown seaweed Fucus distichus Linnaeus was observed to be 130(7) Bq/kg in samples collected in North Vancouver 11 days following the accident and 67(6) Bq/kg in samples collected from the Bam
