Tracking the Fallout and Fate of Fukushima Iodine-129 in Rain and Groundwater

Matt Herod December 21, 2015

A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates the environmental fate of the long lived radioisotope of iodine, 129I, which was released by the Fukushima-Daichii Nuclear Accident (FDNA). Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increased 5-15 times above pre-Fukushima concentrations and then rapidly returned to background. The concentrations of 129I …[Read More]

My EGU2013 (Tuesday)

Matt Herod April 11, 2013

Firstly, I am not actually attending EGU 2013 this year. However, that does not mean I can’t participate. In fact, it has been incredibly easy for to me join in, although I have had to wake up very early in the morning to make up for the time difference between Vienna and Ottawa. I took …[Read More]

Research Highlight – Variations of 129I in the atmospheric fallout of Tokyo, Japan: 1963-2003

Matt Herod December 13, 2012

I occasionally like to focus in on what I view as a key paper either in my particular field of iodine geochemistry or in the geochemical world at large. In this instance I have decided to highlight a paper in my field that releases a fantastic wealth of data that is matched nowhere else in the literature I have …[Read More]

About

The term geosphere is an all-encompassing word that incorporates just about every aspect of the earth sciences. This means that topics ranging from geophysics to geochemistry to geobiology are part of the geosphere. The blog Geosphere honours its namesake by covering any and every topic in the geosciences. The principal goal of Geosphere and its author, Matt Herod, is to make science clear for anyone that should stumble in and enhance awareness of the geosphere for all. With this in mind I encourage any who have questions to post, comment or email me.
