What we found:

137-Cesium activity = 1.3 (+/- 0.1) Bq m-3 (Becquerel per meter cubed of seawater)
134-Cesium activity = Not Detected
Water Temperature = 10.5 C

The InFORM team collected a seawater sample in collaboration with citizen scientists in Victoria on Wednesday, Oct. 15 at the Ogden Point Breakwater (map shown below).  The sample was processed and the amount of gamma emitting isotopes determined using a high purity germanium detector.  We look primarily for radioisotopes of cesium (134-Cs half life ~2 years and 137-Cs half life ~ 30 years) for the following reasons: Continue reading First Seawater Monitoring Result From Victoria, BC: No Fukushima Contamination as of Oct. 15, 2014

More Citizen Science Sampling Kits Being Shipped Out

By Jay T. Cullen

@JayTCullen and @FukushimaInFORM

Shown below are sampling kits that will ship out today for our citizen science volunteers in Tofino, Winter Harbour, Hadia Gwaii – Sandspit and Port Hardy BC.  Staged for pick up are Lax Kw’alaams, Prince Rupert, Powell River and Haida Gwaii – Masset.  Results of seawater monitoring for Fukushima derived radioactivity will be made public as they are available.

How do we process seawater samples?

By Jay T. Cullen

The InFORM team is busy processing samples returned to us from our citizen scientist volunteers who collected seawater at various locations in November.  When we receive the seawater we first filter it through a 1 micron ( 1 micron = 10-6 meter) cartridge to remove larger debris and sediments that might be present.
