On 28th November there were reports of a large explosion in the Iranian city of Isfahan, home to the Isfahan Uranium Conversion Facility. link - via Haaretz - The BBC claim that Iran is building a plant at the nuclear research facility to convert yellowcake into three forms...

Between November 1st and 2nd, Krypton-85 went from 3.6 x 10^-3 to 5.3 x 10^-1 becquerels per cm3 in Reactor 2's PCV gas. Also, here is the data for R2's CAMS and pressure: http://www.tepco.co.jp/nu/fukushima-np/f1/images/11110212_level_pr_data_2u-j.pdf I would like to see a graph of all...

Surely LNT is to simplistic? Internal exposure to man made isotopes may have vastly different pathologies than exposure to atmospheric radon. Radon has always been in our environment, likewise cosmic rays. We have evolved with natural sources all around us. What hasn't been in our...

From another forum: RE. Hydrogen in R2's PCV "The source of the hydrogen is presumably cooling water hydrolyzed by direct contact with the damaged fuel. Yet the reactor temperatures are now reading well below 100 degrees C. If the fuel had left the reactor vessel, the hydrogen would be found...

The science ministry is saying that the 40 millisievert source is buried radium-226. Why would someone keep burying this around Setagaya? I imagine it is expensive stuff?

Where has the Silver come from? Neutron capture by silver-109 from the reactors? Is silver in the control rods?

It's always the one you least suspect! :smile: So is number 2 the cause of the I-131 that is turning up across Japan again? Xe-135 has a 9 hour half life, so this must be recent. More evidence of the "impossible" [transient?] criticalities. Has the corium solidified after...

Anyone help?

A document was given to the press in June, which included estimates of radioactive releases in the 1st 100 hours of the crisis. On page 13 a table is given with the following header: 解析で対象とした期間での大気中への放射性物質の放出量の試算値 "Estimated amount of radioactive material released into the atmosphere...

Thanks for explaining the properties of Strontium. If it is more likely to be dissolved in water, than dispersed by air, does that mean that the majority of Strontium produced has ended up in the sea/ground/basement water?

Replace the old plants with passively cooled Generation III designs, invest in the Thorium fuel cycle, triple investment in solar and fusion research. The risks of running the old plants is an increased cancer burden for the world.

Not the first time I've said it, but its (way past) time to decommission all NPPs that over ~35 years old. More 'unforseen' events WILL occur, a combination of time, luck, human error and chaos theory will ensure it. Also, 4 generator failures hit US nuclear plants [AP]...

Great article from the NYT on contamination in Tokyo and the Japanese media's complicity in this debacle. http://www.nytimes.com/2011/10/15/world/asia/radioactive-hot-spots-in-tokyo-point-to-wider-problems.html?_r=1 [pg2] "Some of the results were shocking: the sample that Mr. Hayashida...

Where any other isotopes tested for? "where's there's cesium there's strontium" AFAIK

"in Funabashi, city workers cordoned off an area near a children’s theme park when a citizens’ group detected a level there of 5.82 microsieverts per hour"...
