Metro News, Mar. 24, 2014: Alberta student’s science project finds high radiation levels in grocery-store seafood [...] Bronwyn Delacruz [...] said she was shocked to discover that, in the wake of the 2011 Fukushima nuclear disaster in Japan, the Canadian Food Inspection Agency (CFIA) stopped testing imported foods for radiation in 2012. [...] Delacruz studied a variety of seafoods – particularly seaweeds – as part of an award-winning science project that she will take to a national fair next month. [...] Her results caught the attention of judges at the Peace River Regional Science Fair, who moved her project along to the Canada-Wide Science Fair [...]
Daily Herald Tribune, Mar. 25, 2014: Local science project finds high levels of radiation in seaweed — When Bronwyn Delacruz started testing seaweed in her living room last August, she made an incredible discovery: Something unexpected may be lurking in Canadian waters. [Delacruz] found disconcerting radiation levels in seaweed products from local grocery stores and is concerned for the health of families who may be consuming them. Her research on the subject recently earned gold at the regional Canada-Wide Science Fair [...] Delacruz tested more than 300 individual seaweed samples, with 15 brands exported from New Brunswick, British Columbia, California, Washington, China and Japan. Each was purchased in an Alberta grocery [...] 0.5 Bq per square centimetre is widely considered an actionable level of contamination [...] many of her samples tested well over this amount. [...] Delacruz believes the current has carried dangerous radiation from Japan’s east coast to Canada’s portion of the Pacific Ocean. [...] and believes dangerous radiation may only have reached the Canadian coastline recently. [...] Delacruz is a CWSF Physical Award of Excellence in Physical Earth and Chemical Sciences-winner [...]
Bronwyn Delacruz, Mar. 24, 2014: “Some of the kelp that I found was higher than what the International Atomic Energy Agency sets as radioactive contamination, which is 1,450 counts over a 10-minute period [...] Some of my samples came up as 1,700 or 1,800.”
Bronwyn Delacruz, Mar. 25, 2014: “I think any dose of radiation can be harmful [...] Any dose can cause negative health effects [...] I’m kind of concerned that this is landing in our grocery stores and that if you aren’t measuring it, you could just be eating this and bringing home to your family. [...] Kelp was higher than what was considered dangerous [...] Some of them came up to 1,700, 1,800 (counts). [...] The way the currents and the radiation would arrive in Canada, it wouldn’t arrive until now [...] My pre-Fukushima (nori) measured about 400 (counts) [...] post-Fukushima measured around 500 to 600, which also not dangerous, but it’s considerably higher and statistically significantly higher too. [...] I eat a lot of seaweed in almost everything [...] I would like the government to test before they ‘OK’ imports from other countries [...] they’re just relying on other countries to do it for us. [...] I hope people will open their eyes to this.”
How You Can Help: Delacruz is fundraising to purchase a $15,000 germanium spectrometer for the High School science department that can detect radiation in fish and other complex foods. To donate, call Grande Prairie Public School District Education Foundation at 780-532-4491.
