Canada: salmon was detected radioactive elements, Fukushima-Fukushima due to nuclear proliferation, nuclear accident, salmon-IT information
Canada Victoria University Oceanography experts have said they in Canada salmon on the West Coast, and radioactive elements caesium-134 has been detected for the first time, prove Japan nuclear contamination has spread to North America. This is in Europe and the media have been reported in North America in the near future after being contaminated fish occurs in the Pacific Rim, Canada experts confirm this message for the first time. CCTV reporter in Toronto to interview this expert-JIEYI·kalun Professor at the University of Victoria.
JIEYI·kalun is a Professor of Earth and Ocean Sciences, University of Victoria, starting in 2014, he and his research team and 600 volunteers, began tracking the spread of nuclear pollution, they collected more than 400 species of fish and water samples for testing.

Earth and Ocean Sciences, Victoria University Professor JIEYI·kalun: artificial radioactive elements in order to detect fish, in 2015, we caught some fish, these fish and we've captured in the past 3 years, more than 400 pieces of fish are different. Other fish we did not detect artificial radioactive elements, in which fish we've detected another artificial radioactive cesium-137, so we decided to determine the content and relationships with Fukushima. Our approach is to find the cesium-134 because the isotopes have a half-life of 2 years. We found caesium-134, indicates that the fish is Fukushima affected.
Environment there are traces of cesium-137 and CS-134, they are the result of human activities. Caesium-137 has a half-life of 30 years, so if a cesium-137 was detected in the salmon, is also likely to come from other nuclear activities, such as nuclear testing, etc. Caesium-134 has a half-life of approximately 2 years, Fukushima, in 2011, so if caesium-134 has been detected from the Pacific, from Fukushima will be ascertained, it was known as the "fingerprint of the Fukushima nuclear pollution".
加拿大：三文鱼身上检测到放射性元素，系福岛核污染扩散所致 - 福岛,核事故,三文鱼 - IT资讯
加拿大维多利亚大学的海洋学专家近日表示，他们在加拿大西海岸的三文鱼身上，首次检测到铯-134放射性元素，证明日本福岛核污染已经扩散到北美地区。这是在欧美媒体近期陆续报道北美太平洋沿岸地区出现遭到核污染鱼类后，加拿大专家首次证实这一消息。央视驻多伦多记者前往维多利亚大学采访了这位专家——杰伊·卡伦教授。
杰伊·卡伦是维多利亚大学地球和海洋科学院的教授，从2014年开始，他和他的研究团队以及600名志愿者，开始对福岛核污染的扩散进行跟踪研究，他们收集了400多种鱼类和海水样本用来检测。

维多利亚大学地球和海洋科学院教授杰伊·卡伦：为了检测鱼体内的人工放射性元素，2015年我们捕获了一些鱼，这些鱼和我们在过去3年里捕获过的400多条鱼不同。其它鱼我们没有检测出来人工放射性元素，在这些鱼身上我们检测到了另一种人工放射性元素铯-137，于是我们就决定来测定其含量以及与福岛核事故的关系。我们的方法就是找到铯-134，因为这种同位素有2年的半衰期。我们发现了铯-134，说明鱼已经受到福岛核事故影响。
环境中存在着微量的铯-137与铯-134，它们都是人类核活动的产物。铯-137的半衰期为30年，因此在三文鱼中如果检测到铯-137，也有可能来自其他核活动，如核试验等。铯-134的半衰期约为2年，而福岛核事故发生在2011年，因此如果从太平洋中检测到铯-134，就能确定是来自福岛核泄漏，它也因此被称作是“福岛核污染的指纹”。
