Last evening I spoke at the monthly meeting of Surfrider Vancouver Island, one of InFORM’s non-governmental organization partners, to provide them with an update on our most recent results and progress. Surfrider VI helps to coordinate our citizen science volunteers who sample coastal seawater every month to monitor for Fukushima derived contamination along our beaches from Victoria in the south to Lax Kw’alaams in the north of BC. Surfrider VI is primarily responsible for sampling in Port Renfrew BC which is on the southwest coast of Vancouver Island.
I was pleasantly surprised by Lynn Wharram (Volunteer Coordinator and Combing the Coast BCU team lead) who had produced a short video chronicling her family collecting InFORM’s August 2016 seawater sample from the dock near the Port Renfrew Hotel. You can watch the video below.
You can read more about our citizen science program methods here, our NGO partners here , and our citizen science volunteers here. Thanks again to our volunteers and to Surfrider VI for all the work they do. Go and check them out if you are interested in ocean health (and surfing).
The purpose of this post is to bring to the attention of interested readers a recently released report that provides comprehensive account of the environmental radiation surveillance activities conducted by Health Canada in the months immediately following the Fukushima accident. This report includes an assessment of the overall levels of contamination and resulting impacts to the health of Canadians. Contrary to irresponsible and inaccurate rumors that Health Canada suspended monitoring in the wake of the triple meltdowns, monitoring activities were, in fact, enhanced and expanded to increase the flow of information and improve understanding of the implications of the contamination for environmental and public health. While there was no discernible change in total background radiation a distributed system of monitoring stations and the rapid collection and measurement of environmental samples tracked the trace levels of atmospheric contamination across the country. The report concludes:
conservative estimates of the maximum individual dose from Fukushima was less than 0.0003 (1/ 3,000) of the typical annual dose for a Canadian owing to natural background sources
the additional dose resulting from Fukushima derived contamination is far less than the normal variation in dose from place to place in Canada
there are likely to be no health impacts related to this small, incremental dose
The purpose of this post is to report the most recent results of Kelp Watch 2015 , a program dedicated to monitoring for the presence of Fukushima contamination off our Pacific Coast. This post is the latest in a series dedicated to the public dissemination of information about the impacts of the Fukushima Dai-ichi disaster on the health of the North Pacific Ocean ecosystem and health of North American residents. New results from the third sampling period (January through March 2015) of Kelp Watch 2015 were released on April 6, 2015 and can be found here. As with previously reported results here, here and here no radioactive isotopes from Fukushima were detected in kelp growing at sampling sites spread along our Pacific coast. The absence of 134Cs in kelp suggests that ocean transport of Fukushima contamination had yet to reach North American coastal water. As the contaminated water reaches the shoreline in the coming months Kelp Watch 2015 will help to track the arrival of the plume in time and space.

This short blog summarizes an open access paper published today reporting results from a Canadian monitoring program tasked with documenting the arrival of ocean borne Fukushima contamination along the North American Pacific coast. This diary is part of an ongoing effort to communicate the best science available on the impacts of the Fukushima Dai-ichi meltdowns on the environment. High quality measurements to look for Fukushima derived radiocesium were made in seawater in the North Pacific and Arctic Oceans from 2011 to early 2014. The authors concluded that:
Fukushima derived radiocesium was first detected 1500 km west of British Columbia Canada in June 2012
Contamination was detected on the continental shelf (near coastal waters) in June 2013
By February 2014 Fukushima radiocesium was present at levels similar to preexisting weapons testing derived 137-Cs
These same models predict that total radiocesium levels from weapons testing fallout and Fukushima will likely reach maximum values of ~3-5 Becquerel per cubic meter (Bq m-3 of seawater in 2015-2016 and then decline to fallout background level of ~1 Bq m-3 by 2021
Fukushima will increase northeastern Pacific water to levels last seen in the 1980’s but does not represent a threat to environmental or human health
