No news from Fukushima while reactor one is running hot and in high pressure... this is disgusting.

@LE thank you all information is useful

@salvador very strange that we get no further news on the nitrogen progress#

@Salvador We are waiting for the latest thermals.

@LE Could you synopsize? It's in Japanese, and I (blush) don't know how to google.

@All, does anybody know if N2 was also injected into unit #3 ?

I read the following in Wikipedia: Plutonium is a transuranic radioactive chemical element with the chemical symbol Pu and atomic number 94. It is an actinide metal of silvery-white appearance that tarnishes when exposed to air, forming a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen and silicon. When exposed to moist air, it forms oxides and hydrides that expand the sample up to 70% in volume, which in turn flake off as a powder that can spontaneously ignite. It is also a radioactive poison that accumulates in bone marrow. These and other properties make the handling of plutonium extremely dangerous.

@marie this is the nuclides chart from @LE link
by elainekirk 4/10/2011 11:21:38 PM

@marie rich I can read only a little Japanese, but they measure in two locations: the 3rd floor patio and the parking lot. The normal background radiation is 0,06 µSv/hr. I have no idea about the isotope measurements further down.

www.tepco.co.jp -From April 2nd, we began to transfer the radioactive water we collected
from the Central Environmental Facility to the Unit 4 turbine building.
On April 4th, water level of the pit in the trench of Unit 3 increased
by 15cm from previous day. Pathway of water flow is unknown. We can not
deny the possibility that water in the turbine building of Unit 4 flows
into the trench of Unit 3. So, we stopped transferring water to the
Unit 4 turbine building to make assurance. Present water level of the
pit in the trench of Unit 3 is not changed from the time we stopped
transferring, and is being stable.

Major facilities at the Fukushima No. 1 nuclear power plant, including reactor and turbine buildings, were flooded to a depth of four meters to five meters during the March 11 tsunami, according to Tokyo Electric Power Co.

The tsunami inundated facilities including the Nos. 1 to 4 reactors and turbine buildings and rose as high as about 15 meters above sea level, according to TEPCO. www.yomiuri.co.jp

@elainekirk At the moment over 9000 km because I am in Germany but I will return 30th of April. The city called Tsukuba is about 180 km from the power plant.

TEPCO is now working to set up a water transfer hose to clear more contaminated water that has flooded the basements of the turbine buildings of the No. 2 reactor and other facilities. www.yomiuri.co.jp

The government and plant operator Tokyo Electric Power Co. have repeatedly said there will be no major health impact "for the time being" and that there will be no "immediate" effects. <...> Monitoring data has shown the total fallout of cesium-137 in Hitachinaka, Ibaraki Prefecture, for 18 days through Tuesday morning was 26,399 becquerels per square meter. In Shinjuku Ward, Tokyo, the figure was 6,615 becquerels per square meter.

Rain on March 21-22--the first since the nuclear crisis began--brought down a large amount of cesium-137, spreading the contamination to Tokyo and 13 prefectures in and around the Kanto region. <...>

The level of radioactive fallout in Hitachinaka and some other areas in the wake of the Fukushima crisis is believed to be higher than that reported in the 1979 Three Mile Island accident in the United States, and about the same as that reported in Europe after the Chernobyl incident.

Fallout levels in the Kanto region have been decreasing this month. Daily readings have been about the same as the early 1960s when so many nuclear tests were conducted. Some experts have said these levels pose no threat to people's health. However, highly radioactive water leaked from the Fukushima plant into the ocean could cause severe damage to marine life. www.yomiuri.co.jp

This activity is one of the plains site AIST m × 1.5 m plastic sheet spread of radioactive dust wiped off the sample adhered to one hour, is measured by the germanium detector. Germanium semiconductor detector (pictured below), X is a detector for measuring γ-ray energy lines and. Radiation detection portion is made from a substance called germanium semiconductor. The radiation enters the semiconductor, resulting in a pulsed current. The higher the radiation energy will be large pulse of current. Energy spectrum can be obtained to measure the magnitude of the electric current pulse.

@elainekirk IsotopesMain article: Isotopes of bismuth
The only naturally occurring isotope of bismuth, bismuth-209, was traditionally regarded as the heaviest stable isotope, but it had long been suspected to be unstable on theoretical grounds. This was finally demonstrated in 2003 when researchers at the Institut d'Astrophysique Spatiale in Orsay, France, measured the alpha emission half-life of 209Bi to be 1.9 × 1019 years,[8] over a billion times longer than the current estimated age of the universe. Owing to its extraordinarily long half-life, for all presently known medical and industrial applications bismuth can be treated as if it is stable and non-radioactive. The radioactivity is of academic interest, however, because bismuth is one of few elements whose radioactivity was suspected, and indeed theoretically predicted, before being detected in the laboratory. Bismuth has the longest known alpha decay half life, although tellurium-128 has a double beta decay half-life of over 2.2×1024 years.

Several isotopes of bismuth with short half-lives occur within the radioactive disintegration chains of actinium, radium, and thorium, and more have been synthesized experimentally.

IsotopesMain article: Isotopes of lead
Lead can be found or produced in many isotopes, with three of them being stable. The four natural isotopes of lead are 204Pb, 206Pb, 207Pb, and 208Pb with the slightly radioactive 204Pb regarded as completely primordial lead, and the stable isotopes 206, 207, 208 being formed probably from the radioactive decay of two isotopes of uranium (U-235 and U-238) and one isotope of thorium (Th 232).

The one common radiogenic isotope of lead, 202Pb, has a half life of about 53,000 years.[2]

The government has decided to shorten the period required for the presumption of death of persons missing in disasters from the current one year to three months, it has been learned.

The change will allow the timely payments of life insurance benefits, survivors' benefits from workers' compensation and pension payments to families of missing people presumed killed in the March 11 disaster. www.yomiuri.co.jp
