- Minami Soma’s ‘Black Dust’ With Over 10 Million Bq/Kg Of Radioactive Cesium, Says Assemblyman Ooyama


- New Studies on Mystery ‘Black Substances’ Released: Fuel core materials from Fukushima plant detected — Plutonium, Uranium-236, Curium discharged into environment likely in form of fine particles (PHOTO) (ENENews, March 7,2 014):

Environmental Science & Technology (ACS Publications), March 6, 2014: Isotopic compositions of 236U and Pu isotopes in “Black Substances” collected from roadsides in Fukushima Prefecture: fallout from the Fukushima Dai-ichi Nuclear Power Plant accident — Black colored road dusts were collected in high radiation areas in Fukushima Prefecture. Measurement of 236U and Pu isotopes and 134,137Cs in samples was performed in order to confirm whether refractory elements such as U and Pu from the fuel core were discharged [...] The concentrations of 134,137Cs in all samples were exceptionally high, ranging from 0.43 to 17.7 MBq/kg, respectively. 239+240Pu was detected at low levels, ranging from 0.18 to 1.14 Bq/kg and with high 238Pu/239+240Pu activity ratios of 1.64 to 2.64. 236U was successfully determined in the range 0.28 to 6.74 x10^-4 Bq/kg. The observed activity ratios for 236U/239+240Pu were in reasonable agreement with those calculated for the fuel core inventories, indicating that trace amounts of U from the fuel cores were released together with Pu isotopes, but without large fractionation. The quantities of U and 239+240Pu, emitted to the atmosphere were estimated as 2.3×10^9 Bq (150 g) and 3.9×10^6 Bq (580 mg), respectively. [...] fractionation between volatile and refractory radionuclides associated with the dispersal/deposition processes with distance from the [FDNPP] was found.

Description:

http://www.agreenroadproject.org Highly radioactive snow with counts of up to 65 CPM was measured with Geiger Counter in January of 2013. This snow fell in an area that is 25 km from Fukushima Daichi. Minamisōma is a city located in Fukushima Prefecture, Japan. As of May, 1, 2011, the city has an estimated population of 68,745 and a population density of 60 persons per km². The total area is 398.50 km². The Japanese government says this area is ‘safe’ to live in, as of 2012. Minamisōma is about 25 kilometres (16 miles) north of Fukushima I Nuclear Power Plant, the site of the nuclear accident that followed the 2011 Tōhoku earthquake and tsunami.

- 120 Bq/Kg from 2 bags of rice in Minamisoma Fukushima / All the other bags are to be shipped (Fukushima, Oct 10, 2013):

Fukushima prefecture measured Cesium-134/137 over the safety limit from 2 bags of rice produced in Minamisoma city Fukushima in 2013. The reading was equally 120 Bq/kg about both of the bags for some reason. Fukushima prefectural government announced that on 10/8/2013.

- Radioactive Mud In Fukushima School Pools Tops 100,000 Becquerels (Asahi Shimbun, April 22, 2013):

FUKUSHIMA—Radioactive cesium levels exceeding 100,000 becquerels per kilogram were measured in mud accumulated at the bottom of swimming pools at two high schools in and around Fukushima city.

Mud in the pool of a third high school in Minami-Soma, which is closer to the crippled Fukushima No. 1 nuclear plant, showed at least 8,000 becquerels per kilogram.

- NHK: Paper towels are best way to decontaminate Japan — Outside of homes wiped down by hand (VIDEO) (ENENews, Nov 11, 2012):

It’s now known that wiping the roof with paper towels is more effective than high pressure washing. But it takes an enormous amount of man power time and money to clean an entire roof this way. The government estimated the paper towel method cost about $19 per square meter. So Minamisoma decided to limit it to areas such as the eaves.

At 34:45 in

The city hopes to adopt the latest techniques, but the environment ministry wants them to stick to the guidelines. [...]

“What I’m concerned about is [...] this full-scale decontamination of the garden seems to cost twice what we estimated [...] at $19 per square meter the cleanup costs become mind-boggling. It really makes us wonder.”

The deadliest substance on the planet is “no health hazard”.


- Plutonium Detected at 10 Locations in Fukushima (Jiji Press, Aug 21, 2012):

Tokyo, Aug. 21 (Jiji Press)–Plutonium believed to originate from Tokyo Electric Power Co.’s <9501> crippled Fukushima No. 1 nuclear power plant has been detected at 10 locations in four municipalities in Fukushima Prefecture, the science ministry said Tuesday.

The highest reading was 11 becquerels of plutonium-238 per square meter, detected in the town of Namie.

The figure is about 1.4 times more plutonium than that originated from fallout from nuclear weapons tests abroad.

However, the ministry said that there is no health hazard.
