WHICH is apparent if you watch the beginning of the video. Black spots on the screen are heaviest at precisely 1 minute. They seem to come in waves. If those are gamma "bursts, then the stuff is spreading into the environment more and more with each passing day. Previous footage from this camera does not show this phenom. Now it is windy and this could be dust hitting the lens, but some would stick if moist and none does.
More like static during signal transmission maybe? Dunno.

Anybody want to guess what the white smoke like spots are above R2 and R3

One of the things I deal with as a profession is smoke. I own and operate outdoor smoke machines and many other stage effects at my disposal. Low fog like that has to be colder or heavier than atmosphere to fall. Coming from a nuclear meltdown, it is not colder than outside air, it is warmer. So it most likely is oxides - you go it in one mate! Heavy nuclear isotopes..
Good call intrptr and PC. I didnt look long enough. Thought we were seeing R2 steaming again.

Toshiba Corp. announced Thursday that the company had shipped its first major turbine equipment for a nuclear energy project in the United States, where construction of nuclear reactors is expected to resume for the first time in 34 years.
Construction of four reactors is expected to start in the United States by the end of this year. This includes the Nos. 3 and 4 reactors of the Alvin W. Vogtle Electric Generating Plant in Georgia and the Nos. 2 and 3 reactors of the Virgil C. Summer Nuclear Generating Station in South Carolina.
Westinghouse Electric Co., a Toshiba subsidiary, has been awarded a contract to build the reactors and Toshiba manufactures turbine and other auxiliary devices, including a component to condense steam used to drive turbines and generators back into water.
This is the first time Toshiba is exporting large equipment to the United States for nuclear power generation.

Japan is looking to launder tsunami debris in a giant washing machine to get rid of radiation from the Fukushima nuclear accident, a researcher said Friday.
Shredded waste -- including the remains of houses and cars destroyed by the tsunami -- will be put inside a huge water-filled drum where steel attachments will scrub away radioactive particles, the researcher told AFP.
The plan is a joint scheme between Tokyo-based construction company Toda Corp. and the Japan Atomic Energy Agency.

At this point I totally agree. Its time for entombment. Tepco's roadmap to cold shutdown is now by even Tepco and the govts accounting not possible. There should be no more excuses. It would be far better to entomb and at the same time build a massive zeolite lined containment system for the groundwater. Entomb, contain and filter needs to be the new roadmap asap.
The Fukushima Dai-ichi accident—rated 7, the highest possible on the International Nuclear Event Scale released 160 petabecquerels of iodine-131 and 15 PBq of cesium-137, according to Japan’s Nuclear and Industrial Safety Agency. Both radioactive nuclides cause an increased risk of cancer, but cesium-137, with its half-life of about 30 years (compared with eight days for I-131) poses the most concern over the long term:
The isotope is still responsible for radiation in the dead zone surrounding the Chernobyl site. The Japanese government considers a total cesium level—the sum of cesium-137 and cesium-134, which has a half-life of two years—higher than 5000 becquerels per kilogram of soil unsafe for farming.
While many Japanese have turned against nuclear power since the Fukushima Daiichi disaster in March, some local leaders have not: They're lobbying to restart reactors idled for maintenance and resume construction on unfinished ones One big reason: central-government subsidies, paid from a tax levied on power bills. The 33 nuclear municipalities—25 that already host reactors (including two where more are being built), one with its first reactor still under construction and seven others that are considering allowing reactors or nuclear-waste storage—collectively get about ¥120 billion ($1.5 billion) a year for their trouble.
Economy, Trade and Industry Minister Yukio Edano stressed on Dec. 2 the need for a fundamental review of Japan's energy policy in the aftermath of the Fukushima nuclear accident but stopped short of speculating on the fate of the trouble-prone Monju prototype fast-breeder reactor in Fukui Prefecture.
TSUKUBA, Ibaraki Prefecture--Nearly 30,000 becquerels per square meter of cesium-137 fell on Tsukuba in March as a result of the accident at the Fukushima No. 1 nuclear power plant, the government's Meteorological Research Institute said Dec. 1.
The amount was 50 times higher than the previous record level of 550 becquerels, which was measured in Tokyo in 1963 and was the result of deposits from atmospheric nuclear tests. The MRI, affiliated with the Japan Meteorological Agency, said the cesium-137 deposits in Tsukuba in April fell to less than one-tenth the March level, and by summer fell further to several tens of becquerels per square meter, approximately the same levels found in the aftermath of the 1986 Chernobyl accident, researchers said.
"It may take decades for the figures to come down to levels before the Fukushima accident," said Yasuhito Igarashi, a laboratory head at the MRI's Atmospheric Environment and Applied Meteorology Research Department.
The MRI has been engaged in radioactivity measurements since 1954.
On March 31, the budget for fiscal 2011, which was to start the next day, was abruptly frozen, and the researchers were told to suspend the measurements. The latest findings are a fruit of efforts by scientists who ignored that order and continued with the measurements.
The central government, responding to months of criticism from experts, has decided to measure levels of radioactive cesium in soil within the no-entry zone surrounding the stricken Fukushima No. 1 nuclear power plant, sources said Nov. 30.
The government this summer examined soil within a radius of 100 kilometers of the Fukushima plant, but that did not include the area within the 20-kilometer no-entry zone. The government will survey an additional 100 locations, including those within the no-entry zone, by the end of the year by sampling soil to a depth of 10 centimeters.
Depending on the results of the expanded survey, decontamination costs will likely increase, officials said.
A type of mask sold in drugstores for hay-fever sufferers may also prove effective in preventing internal exposure to radioactive cesium, a researcher at the University of Tokyo said.
Shogo Higaki, who specializes in radiochemistry at the university's Radioisotope Center, said on Nov. 30 that he compared levels of cesium that became attached to airborne pollen and dust with levels of cesium on the surface of a three-dimensional, nonwoven pollen mask he wore from 3 p.m. on March 15 to 9 a.m. on March 16.
The results show that the mask almost completely eliminated the amount of cesium inhaled and cut the amount of radioactive iodine ingested by one-third.
Rejected by residents, incinerated waste containing radioactive cesium is being returned to the Tokyo metropolitan area where it originated. The first batch of 18 tons, bound for Kazo, Saitama Prefecture, was loaded onto trucks on Dec. 3. A train carrying the ash will leave JR Odate Station on Dec. 4.
A total of 245 tons of waste incinerated ash, mostly in 25 railway containers, has been temporarily stored since mid-July at facilities in Kosaka and Odate in Akita Prefecture. The cesium is believed to derive from the Fukushima No. 1 nuclear power plant damaged by the March 11 Great East Japan Earthquake.
Residents have been opposed to burying ash even though cesium concentration levels are below government standards.
