Caught Nov, 17, 2013, 37 km south of Nuclear Disaster Site: A Black Sea Bream fish with 12,400 Bq/kg of Cs-137

Literally just four days after I was there, caught about 15 km south of the beach I visited near Iwaki (see my Nov. 18, 2013 blogpost), further away of the leaking nuclear plants), one black sea bream fish – maybe it tickled the toes of the surfers I watched – caught on Novermber 17, 2013, contained a whopping 12,400 Bq/kg of Cs-137, according to this Jan. 11, 2014 article in the Asahi Shimbun, “Fish with very high levels of cesium found near Fukushima


  • Why, again, such delay in scientific news reporting?

Hmmm… Caught on November 17, let’s say the gamma-spectroscopy was started two days later, Nov. 19, the lab results would be in no later than Dec. 10 (For thorough testing with  three week turnaround; could be done faster too), and then… Really, they just waited to tell anyone for a whole month?  News only by January 11, 2014…

Definitely faster than those scientists from California State University who waited almost an entire year to reveal the Iodine-131 levels they discovered in California kelp beds in 2011, and for whatever reason did not even include the radio-cesium levels in their publication, which the same gamma spectroscopy would have revealed as well.

  • More omissions than news…

And did they really go out there filling nets just to pick only 37 black sea bream samples? What about the rest they tested? And what else was in there? Cs-134 for sure, but at what ratio with Cs-137?  Any additional tests done to check on Sr-90 and Pu-239 levels?  How high was the naturally occurring K-40? (would be included in a basic gamma-spectroscopy as well).  What kind of reading does a common Geiger Counter give when it rests on such a radioactive fresh fish?  They must have checked that, no?

  • What about the Iodine in those samples?

Was there any Iodine-131 in there perhaps?  Or did they they throw the fish in a freezer and waited 2 months before testing so I-131 would be unlikely to get detected even IF there was some in it originally? The presence of I-131 would proof recent fissioning/recriticality, as I pointed out before in my August 3, 2013 blogpost, “Radioactive Iodine in Seaweed and Sludge, Summer 2013? (Hints of Recent Criticality Events…)“, as well as in my (just couple days ago) January 9, 2014 blogpost, “Could (natural, normal) radioactive Potassium-40 (K-40) be the main cause of elevated radiation levels in food?“.

As usual, no word on any of this. No link from the newspaper’s online version to a publication with data.   Nothing.   Unfortunately rather typical for mainstream news.
