The purpose of this post is to report analyses carried out by the InFORM project on muscle and blubber samples from a grey whale (Eschrichtius robustus), that beached near Tofino, BC on April 20, 2015. The post is the most recent in a series that aims to communicate results of scientific research into the impact of the Fukushima disaster on the environment. With the cooperation of the Ucluelet Aquarium the InFORM project was able to obtain samples of the whales muscle and blubber which were analyzed for the presence of gamma emitting radioisotopes in Health Canada’s laboratories in Ottawa, ON Canada. The gamma radiation spectra were dominated by naturally occurring radioisotopes, primarily Potassium-40 (40K half life 1.25 billion years), and after 24 hours of counting no Fukushima derived Cesium-134 (134Cs half life ~ 2 years), a fingerprint of the disaster in the environment could be detected. The unfortunate demise of the grey whale is very unlikely to have been the result of acute or chronic radiation exposure owing to Fukushima derived radionuclides in seawater and the whales food.
