According to the video below featuring by Simon Fraser University’s Kris Starosta, a rainwater sample measured in the Vancouver area had levels of radioactive iodine-131 at 10 becquerels/liter [Bq/l], which corresponds to 10^7 particles of I-131 per liter of water [10^7 = 10,000,000].
The post-Fukushima peak for I-131 in the U.S. appears to have been in the San Francisco Bay Area, where levels reached 19.85 Bq/l.
An I-131 level of 19.85 Bq/l detected in the Bay Area rain sample is equivalent to 19,850,000 particles of I-131 per liter.
