24th September 2015 – Still 0.88 MBq/km2 of Cs-134/137 falls in Tokyo monthly
From their report released on 8/31/2015, 0.88 MBq/km2 of Cs-134/137 falls onto Tokyo this July. The sampling location was Shinjuku.
The comparable data on Fukushima prefecture is not listed on the same report for some reason.
In Miyagi prefecture, where is in the North of Fukushima prefecture, the fallout level is 0.55 MBq/km2. The fallout density in Tokyo is higher than Miyagi prefecture.
22nd September 2015 – Cs-134/137 measured from Tokyo tap-water
The density was from 0.00178 to 0.003 Bq/Kg. Cs-134 was detected to prove it is from Fukushima plant.
All the other analyses were carried out by Tokyo Metropolitan Government Bureau of Waterworks or municipal governments and the lowest detectable amount was over 0.5 Bq/kg to show none of the actual readings.
20th September 2015 – The highest I-131 density of this year detected in 2 Fukushima sewage plants
The highest reading was 1,038.4 Bq/Kg of 7/11/2015. The highest density of Cs-134 was also detected, which was 44 Bq/Kg the same day. It rained on 7/8/2015 but the precipitation was only 10.5 mm.
Also in another sewage plant in Koriyama city, 889 Bq/Kg of I-131 was detected from dry sewage sludge. This is also the highest reading of this plant. I-131 kept on being detected for 15 days of this July.
19th September 2015 – Over 700 Fukushima waste bags swept away by torrential floods
Extensive and destructive floods across eastern Japan have swept more than 700 bags containing Contaminated soil and grass into Japan’s rivers, with many still unaccounted for and some spilling their radioactive content into the water system.
25th July 2015 – Cs-134/137 detected from 6 of 6 sea bass samples taken Ibaraki offshore
The sampling location was offshore of Hitachi city, Ibaraki. They were collected around the end of June. The highest reading was 9.7 Bq/Kg.
Cesium-134 was detected from 5 of 6 sea bass samples.
15th July 2015 – Cesium-134/137 measured over 200 percent of safety level from Fukushima rice
According to Ministry of Health, Labour and Welfare, excessive amount of Cs-134/137 was detected from two unpolished rice samples produced in Fukushima city.
The rice was experimentally produced but not distributed, the farmer states. The highest reading was 220 Bq/Kg in total of Cs-134/137. The safety limit is supposed to be 100 Bq/Kg.

16th January 2015 – Japan-Radiation Test Results: 5th Round – We’ve tested our seafood for a fifth time … and again received very reassuring results
Strontium-90: None detected in king salmon, halibut, or albacore tuna. Sockeye salmon contained 1,760 pCi/kg of strontium-90, which is less than half (41%) of the FDA’s safety limit (DIL) of 4,300 pCi/kg.
“Grains, leafy vegetables, and dairy products are the leading sources of dietary strontium-90 in the U.S. diet, and the concentration in U.S.-grown vegetables typically peaks at 9 pCi/kg.”
It is commendable that this company is testing sea food for radioactive contamination.
I am surprised at the amount of Strontium-90 detected in the Sockeye salmon, considering the other isotopes tested for were below reliable equipment detection limits. The question is why did the Sockeye salmon bio-accumulate so much Strontium-90, and the other fish didn’t? Knowing what they are eating and their migration patterns could answer this question. It may turn out that the Strontium source is not from Fukushima.
Strontium-90 is a poison and does not have any dietary health benefit, at any level of contamination!
From previous research, the Sockeye salmon Strontium-90 contamination could affect Sockeye salmon fertility, and cause a crash in fish numbers. It will also be bio-accumulated up the food chain by all its predators, including Humans.
8th October 1971 – Fallout and Reproduction of Ocean Fish Populations E.J. Sternglass, Department of Radiology, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania
Nuclear Fallout causes Fish Population Decline extract:
As will be shown below, very large declines of fish-populations after low-altitude nuclear tests followed by a gradual recovery to pretesting levels have been observed both in the Atlantic and Pacific, strongly suggesting that the eggs of fish and the developing young are far more sensitive to internal radiation from low-level fallout than had been anticipated, very much as in the case of the human-embryo and fetus.
18th May 2015 – Fukushima Radiation Found In Tap Water Around Japan
Testing conducted in February and March of 2015 found cesium in many tap water samples collected around Japan. While the numbers were fairly low it is still a persistent problem since tap water is used in some way in everything that is consumed. In the readings, Tokyo had higher tap water contamination levels than Fukushima City.
April 2015 – Massive internal contamination occurring in Japan, over a wide area, and long distances from Fukushima, as evidenced by house dust test results.
If it is in the house dust, it has to be getting into the air, food and water, of the people living in these homes.

12th March 2015 – Produce worries easing but some fish, wild foods still a problem in wake of Fukushima meltdowns
But concern remains over fish, wild vegetables and wild game. Between April 1 last year and March 1, around 292,000 such samples were tested for radioactive cesium and 502, or 0.17 percent, exceeded the safe threshold, the health ministry said. In fiscal 2012, that ratio stood at 0.85 percent.
In February, wild boar meat from Fukushima Prefecture was found to contain 15,000 becquerels of cesium per kilogram, the highest figure since last April 1.
Highly contaminated wild game was also found in Miyagi, Iwate, Ibaraki, Tochigi, Gunma, Niigata and Saitama prefectures, including wild boar meat from Miyagi that contained 1,300 becquerels of cesium per kilogram and deer meat from Saitama that contained 530 becquerels of cesium per kilogram, according to government data.
If Cesium is present, there is the likely hood that other radioactive isotopes are also present, but not tested for.
In my opinion, the so called Japanese safe limit of 100 Bq/kg of Cesium is set too high, particularly for children, who are much more sensitive to radiation than adults. This short ten minute video explains why 100 Bq/kg of Cesium is too high a limit for children.
