Cesium Saturday

For the first time, seaborne radiation from Japan’s Fukushima nuclear disaster has been detected on the West Coast of the United States.

Cesium-134, the so-called fingerprint of Fukushima, was measured in seawater samples taken from Tillamook Bay and Gold Beach in Oregon, researchers from the Woods Hole Oceanographic Institution are reporting.

Because of its short half-life, cesium-134 can only have come from Fukushima.

Also for the first time, cesium-134 has been detected in a Canadian salmon, the Fukushima InFORM project, led by University of Victoria chemical oceanographer Jay Cullen, is reporting.

In both cases, levels are extremely low, the researchers said, and don’t pose a danger to humans or the environment.

Massive amounts of contaminated water were released from the crippled nuclear plant following a 9.0 magnitude earthquake and tsunami in March 2011. More radiation was released to the air, then fell to the sea.

    Humans as glow sticks, what a concept.

    Writer rather ignorant. Caesium 134 has a half life of just 2 years. It is caesium 137, with a half life of 30 years that is somewhat troublesome.

    Well, well. The Wehrmacht was high on supplied meth, according to a carefully researched book reviewed in today’s TNYT.

    Never say never. Decided to stick walk through the snow, up B Street and continuing along Spokane Street and thence down to the Tokyo Seoul. Required 26 minutes.

    The small ditch behind my place has turned into a river, thought I saw a couple kayakers…

    I was reading the obits and a 97 year old dude died on his birthday, that seems weird and ultra-coincidental.

    Home from the Washington Idaho Symphony concert. My goodness, that was fine! The flute player, Ann Y., gave me a lift else I would still be completing the 45 minute walk down from the high school auditorium. Oh yes, gave my congratulations to Keadrin, Alice’s oboe instructor and also the director before I started walking.

    All went well but I forgot my far seers so I will have to go back up to the high school on Monday to see if the spectacles are in the lost & found.
