The purpose of this post is to introduce a brief, informal movie made while using a Geiger Counter in the laboratory today. This diary is part of an ongoing effort to communicate what the scientific community is learning about the impact of the Fukushima disaster on environmental and public health. A Geiger Counter was used to examine ionizing radiation counts per minute in the laboratory owing to background radioactivity, the concentrated natural and man made isotopes in 20 liters of seawater collected by InFORM citizen scientist volunteers, the uranium oxide glaze on a Fiestaware dinner platter and Uraninite ore mined from New Hampshire. This simple demonstration supports more sensitive measurements indicating our citizen scientists are exposed to no more ionizing radiation than is typical of background when collecting seawater samples.
This is a short video made on April 4, 2015 at Botanical Beach near Port Renfrew BC, one of our citizen scientist sampling locations organized by Surfrider Vancouver Island. Botanical Beach is at the north end of the Juan de Fuca Provincial Park on the southwest shore of Vancouver Island.
We arrived on the rising tide when the larger, more impressive tide pools were already submerged but this little pool shows the main types of organisms one can find there. Almost got our feet wet in the end.
The purpose of this post is to report the most recent results of Kelp Watch 2015 , a program dedicated to monitoring for the presence of Fukushima contamination off our Pacific Coast. This post is the latest in a series dedicated to the public dissemination of information about the impacts of the Fukushima Dai-ichi disaster on the health of the North Pacific Ocean ecosystem and health of North American residents. New results from the third sampling period (January through March 2015) of Kelp Watch 2015 were released on April 6, 2015 and can be found here. As with previously reported results here, here and here no radioactive isotopes from Fukushima were detected in kelp growing at sampling sites spread along our Pacific coast. The absence of 134Cs in kelp suggests that ocean transport of Fukushima contamination had yet to reach North American coastal water. As the contaminated water reaches the shoreline in the coming months Kelp Watch 2015 will help to track the arrival of the plume in time and space. Continue reading
