#Fukushima I Nuke Plant: Radioactive Tellurium Detected in Seawater at Water Intake

Radioactive tellurium was detected for the first time in the seawater at the water intake canal for the Reactor 1, but TEPCO thinks it's just a mix-up for some unknown reason, according to Yomiuri Shinbun (6/29/2011).

So I went to look for the original data at TEPCO.

It turns out that tellurium-129m (half-life 34 days) was found near the water intake canal for the Reactor 1, AND tellurium-129 (half-life 70 minutes) was found near the water intake canal for the Reactor 4. Tellurium-129 was also found in deep-sea water 8 kilometers off the coast of Fukushima.

Some kind of a mix-up.

TEPCO dumped 143 pages of "confirmed" data (no English yet) on types of nuclides and density found at and around Fukushima I Nuclear Power Plant in air and water on June 29. The company releases many of the data everyday or at a regular interval but the nuclides announced daily are iodine-131, cesium-134 and -137 only. For other nuclides, after being excoriated by NISA in early days of the crisis, they've stopped releasing the data until "confirmed".

It was on page 74, as part of the "confirmed" results of the seawater samples taken on June 4:

Te-129m (half-life 34 days): 720 becquerels/liter, outside the silt fence in front of the Reactor 1 water intake canal.

The legal safety limit for the exhaust water from a nuclear power plant is 300 becquerels/liter.

Then, on page 99 for the test results for the samples taken on June 12:

Te-129 (half-life 70 minutes): 230 becquerels/liter, outside the silt fence in front of the Reactor 4 water intake canal.

Te-129 was also found in the deep seawater 8 kilometers off the coast of Minami-Soma City and Onahama on June 7 (pages 27, 28) and June 9 (page 39) separately.

No data on this file on radioactive strontium (89 and 90), which is reported separately. No word ever on plutonium in any water or ocean soil.

Merci Niigata pour ton texte français (dans un autre commentaire). Es-tu japonais ou américain ?

If they are referring to the short half-life isotope found that far from the reactors, ..

Half-information, always half-information from TEPCO.

is there a link to a schematic of all these intake valves and silt fences (with flow directions)?

it's impossible to follow these articles without one.

it's not good, at all. You folks in Japan have a monumental disaster to cope with, and from what I have read and seen, radiation is basically spread across the globe, particularly in the northern hemisphere, at this point in time.

I wish you all the best, and i would like to be there with you....your friend in USA, Woop.

I think it is from the corium from the 5 cores that were in the large cooling pond ..
It is the China Syndrome, and it is already deep underground for this to occur.
Nothing can stop this now.

Japan needs to react responsibly with honour, and protect other nations, even if it means sacrificing their own.

It is time for big holes, diggers, rock crushers, concrete block making machines,and 2-3 million liquators to make the ultimate sacrifice, and demolish these reactors piece by piece, and reprocess the materials to recovery materials, and to safely store contyaminated materials.

Japan has caused this disaster, and inflicted on others, some of whom opposed nuclear power from the outset.

Japan must act to clean this up immediately, whatever the cost. Immediately.
No more ongoing chain reactions. No more polution. No more death for future generations.

Liquidate every part of Fukushima, recover materials, and intern everything in a huge hole filled with concrete.

DO IT!
