Wednesday, January 7, 2015, 8:09 PM – Radioactive isotopes originating from the Fukushima nuclear power plant in Japan have been slowly drifting across the Pacific Ocean since March 2011, and Canadian scientists have been using this to test some of their most basic ideas of how ocean currents work.

Scientific Study of Radioactive Cesium Accumulation by Salmon

By Jay T. Cullen

@JayTCullen and @FukushimaInFORM

Male spawning phase Oncorhynchus nerka. When landlocked (freshwater phase) this sockeye salmon is referred to as kokanee.

 

The purpose of this post is to report a recently published study (behind pay wall) that examined how and how much radioactive cesium is accumulated by salmonids (e.g. salmon and trout). This post is part of an series started in 2013 to communicate the results of scientific research into the impact of the Fukushima Dai-ichi triple meltdowns on the environment. Yamamoto and colleagues carried out two experiments (one lake cage experiment and a laboratory experiment) to examine the accumulation of radiocesium from water and food by kokanee (Oncorhynchus nerka) and masu salmon (Oncorhynchus masou). The conclusions of the study were as follows:

Testing the waters for Fukushima

Despite the doom porn circulating on the Internet, there has been no radiation from Fukushima detected yet along the Salish Sea – or if you prefer, the Strait of Georgia.

That’s according to Jay Cullen, a chemical oceanographer at the University of Victoria.

How do Radiation Activities Relate to Contaminant Concentrations?

By Jay T. Cullen

@JayTCullen

The purpose of this post is to give a brief overview of how the activity of radionuclides correspond to the concentration of radionuclides measured in environmental samples. There appears to be some confusion in the public and within the scientific community as to how units are used and the degree of their interchangeability. This post is somewhat technical but falls into the category of “In Case You’re Interested” (ICYI), an acronym I am shamelessly borrowing from a fine book (Everything and More: A Compact History of Infinity) by one of my favorite writers David F. Wallace.

Interview on CBC Radio Daybreak North About InFORM with George Baker

Radio interview related to broadcast by CBC Daybreak North on Dec. 10, 2014 by George Baker.  The live radio broadcast highlights efforts of volunteer, citizen scientists Laurel Stueck (student) and Cheryl Paavola (Instructor and Science Lab Tech) at Northwest Community College – Prince Rupert collecting the first seawater sample there in November 2014.
