Back in business

24 Comments

Hiromitsu Ito, left, 53, oyster fisherman, and Yuki Miura, 23, fisherman apprentice, work on their boat after harvesting oysters from one of their oyster farms in Ogatsu town, Miyagi Prefecture. Ito lost his home, his fishing boats, and his oyster beds, following the 2011 tsunami just after he had taken out a loan to begin oyster processing. Ito and his business partners used funds from the membership fees to help fishermen get back up and running. They are also training newcomers like Miura, a fisherman apprentice, hoping to keep the industry alive.

Good to see they are up and running again, but I can't help wonering about the product, as all oysters do is filter the water. May the currents be kind on them.

There is no radiation. Everything is under control. See! People are getting back to work. Abe is great!

Fukushima Diary ran a story in 2012 about an oyster farm in Kesennuma Miyagi.

I would have no problem eating these oysters, look very tasty. If we think in the U.S. the limit for radioactive cesium is 1200 bq / kg in foods. Europe the limit of 1,000 bq / kg. While in Japan the limit is 100 bq / kg. Twelve times more stringent that American standard safety. Could I make a tea using this "contaminated water" of fukushima.

The way the currents flow from north to south, the coast off Miyagi won't be receiving any radiation leaking into the ocean from the Fukushima power plant. The oyster beds were destroyed by the tsunami. I think the French helped out with free oysters?

Fukushima Diary is not a reliable source. Their article on super-sized vegetables caused by radiation last year was compiled of file photos of vegetables from all over the world, some of them quite old. They have an agenda, and they will bend the facts to fit it.

Best luck to the oystermen.

Some people rave over oysters but I've never been able to take to them. Always seemed to me like eating runny snot.

According to TEPCO's Tests they did find contamination offshore of Miyagi Prefecture

Well Imagine that...Fukushima Diary the not a reliable source. Actually Reads TEPCO's Page & Carried the story....

Melissa, that doesn't mean the the conclusions they draw are correct, and does not in any way excuse outright lies.

From who??? TEPCO lol

-3 ( +0 / -3 )

The level of radiation in the TEPCO report is like 0.0019 Bq/L which is less than what would be found in any ocean, especially the Pacific Ocean which was the place for so many of the huge atomic bomb testing.

All water on the Earth, including seawater, has some radionuclides in it. In the following table, the oceans' volumes were calculated from the 1990 World Almanac:

Pacific = 6.549 x 1017 m3

The release of radioisotopes from the Fukushima Dai-ichi nuclear power plant in March 2011 amounts to the largest-ever accidental release of radiation to the ocean. It came mostly in the form of iodine-131, cesium-134 and cesium-137, the primary radioisotopes released from the reactors, reported Ken Buesseler, a marine chemist at Woods Hole Oceanographic Institution. http://www.whoi.edu/oceanus/feature/radioisotopes-in-the-ocean

Let’s make it clear: the release of radioactive contamination from the Fukushima NPP to the environment — the air, the land, and the ocean — is a massive disaster.

Cesium 134 has a half life of 2 years & both C-134 & C-137 were found in some areas offshore of Miyagi Prefecture & in higher levels than 0.0019 Bq/L.

@Utrack

maybe so but the TEPCO link you provided shows only very low levels?

Radiation map of the ocean off Fukushima http://i2.wp.com/www.tatoott1009.com/wp-content/uploads/2014/01/Untitled211.jpg?resize=823%2C619

There are radiation hotspots in Miyagi which could be a problem when they are next to a river which flows into the ocean. Like the Abukuma River in Miyagi Prefecture, 70 km north of the plant. A Tokyo University team discovered relatively high levels of cesium-137 near the mouth of the river. Contractors which making decontamination work have been found to dumping the debris on river banks? For example, 1.6 km east of the Abukuma River estuary, the research team found a hot spot with average concentrations of 1,029 becquerels per kilogram of mud.

Ha, good one! Yep, we can really trust TEPCO.

Yasukunishrine - so with the U.S.' and whoever else's higher cesium limits, does that mean their oysters are more contaminated than the ones from Miyagi? And would you feed your

Would you feed your kid oysters from there?

Cesium is nasty according to Heyltex

A radioactive element has a constant rate of disintegration that is reflected by its physical half-life. The rate of element elimination from the body is reflected by its biologic half-life. The combined rate of radiation disintegration and rate of element elimination is reflected by the effective half-life. Cesium-137 (137Cs) has a physical half-life of 30 years with a beta energy peak at 174.0 keV.

Following entry into the blood, it is distributed uniformly through all body tissues. Approximately 10% of Cesium is eliminated rapidly with a biological half-life of 2 days, and 90% is eliminated more slowly, with a biological half-life of 110 days. Less than 1% of the Cesium was retained with a longer biological half-life of about 500 days. Cesium follows the movement of potassium and is excreted into the intestine, reabsorbed from the gut into the blood, then to the bile, where it is excreted again into the gut (enterohepatic circulation). Without Prussian blue insoluble treatment, ~80% of Cesium is excreted through the kidneys and ~20% in the feces. Because of Cesium’s long physical half-life, the rate of radiation elimination is similar to the rate of element elimination from the body.

Cesium accumulates in the body through re-absorption & ingestion..

According to Heyltex

While Prussian blue increases the rate of elimination of radioactive Cesium-137 and Thallium-201 from the body, it does not treat complications of radiation toxicity, such as bone marrow suppression, neutropenia, or thrombocytopenia. Patients suspected of being internally contaminated with Cesium-137 should be monitored for radiation toxicity and treated as necessary. Prussian blue might not increase the rates of elimination from the body of radioactive elements other than Cesium-137 and patients exposed to radioactive elements in addition to Cesium-137 may require additional, concomitant treatment with other agents.

Cesium-137 can do damage....

Why are some posters concentrating on caesium-137 when the post is about oyster farms in Ogatsu town, which is quite far north from the Fukushima plant, and to date there's no data suggesting that the oysters are contaminated and will probably be tested before being released into the food market. The land based radiation readings in that area are only showing normal background levels. We don't need to go off on pet tangents when there are none?

TEPCO reported Cesium 134-137 offshore of the Miyagi Prefecture.

@Utrack

TEPCO reported Cesium 134-137 offshore of the Miyagi Prefecture.

And again in the TEPCO report you link again the highest reading for Cs-137 is 0.0093 Bq/L. That's for the bay of Ishinomaki. There's no data in the report about Ogatsu town.

There are many locations in America with higher levels of caesium what's your view on that?

Ever heard of Exports....& It's good to know what's going on in the world since we're all connected by water.....
