Strontium-89

Radioactive Strontium Found in Central Tokyo!

by

– Radioactive Strontium Found in Central Tokyo (EX-SKF, Nov. 21, 2011):

(UPDATE-2) Asahi Shinbun carried the news:

(UPDATE) So far, it is dead silence from the Japanese MSMs; even the critical papers like Tokyo Shinbun is mum on strontium in Tokyo.

—————————————————-

A citizen group did the soil survey of three locations in central Tokyo, and had the soil samples tested for radioactive cesium and strontium. All three had both.

Summary of reporting by Yasumi Iwakami, independent journalist:

Locations and amounts of radioactive materials:
Kiyosumi Shirakawa Station, Koto-ku:
Radioactive cesium (134 and 137 combined): 19,126 Bq/kg
Radioactive strontium (89 and 90 combined): 44 Bq/kg

Yurakucho Station, Chiyoda-ku:
Radioactive cesium (134 and 137 combined): 20,955 Bq/kg
Radioactive strontium (89 and 90 combined): 51 Bq/kg

Front of the Ministry of Economy, Trade and Industry, Chiyoda-ku:
Radioactive cesium (134 and 137 combined): 48,176 Bq/kg
Radioactive strontium (89 and 90 combined): 48 Bq/kg

It’s a poetic justice that the amount of radioactive cesium is the highest at METI. I hear TEPCO’s headquarter building in Tokyo also enjoys rather high radiation.

– Pregnant Mothers Going Back to Minami Soma City to Give Birth (EX-SKF, September 6, 2011):

I just don’t know what to say.

NHK’s program “Close-up Gendai” aired the episode on August 31 (which you can view at the program’s site here) about a 72-year-old obstetrician and over 50 pregnant mothers coming back to Minami Soma City to give birth.

The reason for coming back to their homes in Minami Soma City, even if the radiation level remains elevated, is that they were totally stressed out in the evacuation centers. When asked why she came back to the city, one young mother coming to see the obstetrician says, “Well, it was very cold sleeping on the hard floor of the gymnasium, and we thought our home would be better.”

While the national government created the evacuation-ready zone in Minami Soma City and advised small children and pregnant women to stay out of the zone, there was no actual support as to where they, particularly pregnant women, can stay comfortably outside the zone.

– Highly toxic plutonium detected in soil 45 km away from Fukushima nuclear complex (Mainichi, Oct. 1, 2011):

The Ministry of Education, Culture, Sports, Science and Technology announced on Sept. 30 that it had detected highly-toxic plutonium apparently from the crippled Fukushima No. 1 Nuclear Power plant in soil at six locations including Iitate village in Fukushima Prefecture.

It is the first discovery of the highly-toxic radioactive substance outside the nuclear plant since the outbreak of the disaster in mid-March. The ministry also said radioactive strontium was detected in a wide swath of Fukushima Prefecture within a radius of 80 kilometers from the troubled nuclear power plant, underscoring the fact that the nuclear crisis has been affecting wide areas.

The ministry conducted inspections on soil at 100 locations within a radius of 80 kilometers from the crippled nuclear power plant in June and July. Plutonium-238, believed to have come from the crippled nuclear plant, was detected in six locations including Iitate, Futaba and Namie. Plutonium-239 and -240 were also detected in many locations, but the ministry said it was not clear whether they were directly linked to the Fukushima nuclear crisis.

According to the ministry, the levels of radiation in the plutonium detected fall below the levels of radiation in plutonium believed to have come from atmospheric nuclear tests conducted in the past. But because very little plutonium-238 had been detected before the outbreak of the nuclear crisis, the ministry concluded that it had come from the Fukushima nuclear power plant.

Namie registered the highest density of plutonium-238 with 4 becquerels per one square meter of soil. The combined density of 15 becquerels of plutonium-239 and -240 was detected in one square meter of soil in Minamisoma, while 0.82 becquerels of plutonium-238 was detected in one square meter of soil in Iitate. The ministry said, “The radiation levels of the plutonium are not high enough to affect human bodies.” The half life of plutonium-238 is 88 years. Tokyo Electric Power Co. (TEPCO) had previously explained that plutonium is heavier than radioactive cesium and therefore it is difficult for the radioactive substance to travel to distant places.

Meanwhile, the ministry said it had detected radioactive strontium-89 in nearly half of the locations inspected, including Shirakawa, about 79 kilometers from the nuclear plant. Because the half life of strontium-89 is only about 50 days, the ministry concluded that all the findings of the radioactive substance were linked to the Fukushima nuclear power plant. Namie registered the highest level of radiation, with 22,000 becquerels per one square meter of soil. Noting differences in distribution between the plutonium and radioactive cesium from the Fukushima nuclear power plant, the ministry plans to carry out more inspections because strontium can easily builds up in bones.

Radioactive Strontium Found Three Miles Off Fukushima Coast In Ocean Soil

by

– #Fukushima I Nuke Plant: Radioactive Strontium from Ocean Soil Off the Plant (EX_SKF, June 25, 2011):

Strontium-89 and strontium-90 have been detected in soil and ocean water, but for the first time they have been detected in ocean soil 3 kilometers off the coast where Fukushima I Nuclear Power Plant is located. The samples from 2 locations were taken on June 2.

The Ministry of Education and Science have announced the detection of radioactive cesium from the ocean soil, but has been silent about strontium.

Strontium-89 (half-life 51 days) was detected at 140 becquerels/kg at one location (off Minami-Soma City), 42 becquerels/kg at the other (off Naraha-machi). Strontium-90 (half-life 29 year) was detected at 44 becquerels/kg at one location, 10 becquerels/kg at the other.

There is no safety standard set for radioactive strontium. The amount detected in regular sampling surveys from 1999 to 2008 at Fukushima II (not I) was ND (not detected) to 0.17 becquerel/kg.

The survey also detected a minute amount of plutonium-239+plutonium-240.

Clearly, no one cares any more in Japan. No major news outlet carried the news, not at least on line. The only paper that carried this news was the Japan Communist Party’s newspaper, Akahata (red flag).

Here’s TEPCO’s press release on June 25, 2011:

A slow dribbling of information on the extent of radiation contamination, so that people in Japan don’t connect the dots and figure out that their soil, water, ocean have probably been contaminated beyond repair.

It took the Ministry of Education and Science one month to announce the test result, just like when it announced the result for the locations 30 kilometers away from the plant back in mid April.

Asahi Shinbun (6/1/2011):

???????????????????????????????????????????????????????????????????????????????

The Ministry of Education and Science announced on May 31 that the radioactive strontium-90 was detected from the soil samples at 4 locations in Okuma-machi and Futaba-machi, the towns located inside the 10-kilometer radius from Fukushima I Nuke Plant.

Radioactive Strontium Found In Hawaii Milk

– Dr. Helen Caldicott On The Japan Nuclear Disaster – The Truth MSM Won’t Tell You! (Video)

Apr. 27 — A radioactive isotope of strontium has been detected in American milk for the first time since Japan’s nuclear disaster—in a sample from Hilo, Hawaii—the Environmental Protection Agency revealed yesterday.

“We have completed our first strontium milk sample analysis and found trace amounts of strontium-89 in a milk sample from Hilo, Hawaii. The level was approximately 27,000 times below the Derived Intervention Level set by the U.S. Food and Drug Administration,” EPA said in a statement emailed to me yesterday afternoon. EPA posted the test result at epa.gov in a pdf.

EPA found 1.4 picoCuries per liter of strontium-89 in a milk sample collected in Hilo on April 4.

Although the EPA tests milk, the FDA regulates it, and the FDA’s Derived Intervention Level—the standard observed for food—is 4,400 pCi/L for strontium-90. I’m working to confirm whether FDA has a separate DIL for Sr-89.

The EPA’s Maximum Contamination Level for Sr-89 in drinking water is 20 pCi/L. (For more on the difference between EPA and FDA standards, see “Why Does FDA Tolerate More Radiation Than EPA?“)
