Radiation Concentration Highest Around March 15 Right After No.3’s Explosion; Huge Amount of Iodine 135; Disclosed Data of I-131 and Cs-137 Merely Shows a Tip of the Iceberg
After the 3.11, CTBTO Takasaki (Gunma, Japan) Radionuclide Monitoring Station detected in air Technetium 99m (Tc-99m), Barium 140 (Ba-140), Promethium 151 (Pm-151), Lantern 140 (La-140), Tellurium 129/129m/132 (Te-), Iodine 131/132/133/135 (I-), Cesium 134/136/137 (Cs-), and Xenon 131m/133(Xe-), etc. The Station was not able to measure the exact value of Xe-131m/133 gas due to extremely high density of Xenon on March 15. The Station is one of the CTBTO international observation networks, not a governmental agency.

Pay attention to the extremely high density in air that was detected from March 15 to March 16. Although the data from March 14 to March 15 are missing (probably it could reveal the highest density because of the explosion at the #3 reator's fuel pool), it can prove what I have been saying based on the data by the Japan Metrological Agency that the largest amount of radioactive materials got diffused during the first one week after the 3.11. Ministry of Education (MEXT) has disclosed only data of a few isotopes of Iodine and Cesium after March 19, which only indicates a tip of the iceberg.
There are other interesting findings in the data. First, it was not only right after March 14 that the increased amount of radioactivity was detected, but there are also increases of radioactivity on March 21, 30, and April 18. Second, total amount of radioactive Cesium has been counted twice as high as the total amount of Cesium 137 only, similarly, total amount of radioactive Iodine at least 42 times higher than the total amount of Iodine 131, and the Iodine 135, though detected only on March 16, even scored the highest amount of detection among any radionuclides in the data.
It is important to know that Iodine 131 becomes Xenon 131m, Iodine 135 becomes Xenon 135, and Xenon 135 becomes Cesium 135 (which half-life is 2,300,000 years) after omitting all the radiation. Then, can it be said that there must be huge amount of Cesium 135 have been accumulated on the land of Japan? (Does anyone know of data on Cesium 135 in Japan?)
*Mr. Hiroaki Koide from Kyoto University has mentioned about this mysterious Iodine 135. He said that the huge amount of Iodine 135 supports the speculation of nuclear explosion at the #3 reactor on March 14.
MEXT Aeromonitoring Shows Cesium Contamination Worse Than Chernobyl: Areas 80km Outside of the Plant Already Being the Chernobyl Evacuation Zone
On May 6, the Ministry of Education, Culture, Sport, Science and Technology (MEXT) almost secretly released the data by airmonitoring on the accumulated Cesium 137 on the land. The data shows horrendous facts about the areas near the Fukushima Daiichi Nuclear Plant. It found 3,000,000 Bq/ms (81 Ci/m2) of Cesium 137, which could be one of the worst radioactive contamination in the history, in the large area including Iidate Village located right outside of the 30km zone. It also found 600,000 Bq/ms (16.2 Ci/km2) of Cesium 137 contamination in the area between 30km to 60km outside of the plant. The area of 60km to 80km out of the plant detected 300,000 Bq/m2 (8Ci/km2). In the Chernobyl accident, residents were recommended voluntary migration in the area of Cesium 137 detection between 5 Ci/km2 to 15 Ci/km2 (the second contaminated area); residents who were at the area over 15 Ci/km2 of Cesium 137 were ordered mandatory displacement (the first contaminated area). It is clear that the Japanese government's intervention after the accident is much less humane than the former Soviet Union.
*1 Ci = 37,000,000,000 Bq = 37,000 MBq (MBq = 1,000,000 Bq); 1km2 = 1,000,000 m2
The data of Cesium 134 (half-life span is 2.1 years) have been added to its online database by the Ministry of Education, Culture, Sport, Science and Technology (MEXT) since April 25, 2011. MEXT had disclosed data of only Cesium 137 and Iodine 131. According to the data, nearly identical proportion of Cesium 134 has been found compared to the amount of Cesium 137. Since Cesium 136 also has been found by a non-government research group, we can at least double the amount of previously reported amount of Cesium 137 in order to know the total amount of radioactive Cesium.
Tokyo Government has released data including precipitations of Cesium 134 since March 19, 2011. According to the report, 6,803 MBq/km2 (MBq = megabecquerel) of Cesium 134 and 6,968 MBq/km2 of Cesium 137 were detected between March 19 to May 1, 2011. The US EPA also detected that Cesium 134 and Cesium 137 in nearly identical proportion in the U.S., coinciding the data with Tokyo.
Xenon 133, Cesium 136, Tellurium 129 and 132 Have Been Found in Chiba Prefecture; Accumulated Amount of Cesium 137 on the Surface of the Land Counts Over 53,000 MBq/km2 (=The Chernobyl Third Contamination Zone)
Japan Chemical Analysis Center (non-government) in Chiba Prefecture has detected Xenon 133 of 1,300 Bq/m3 in the air, which is 1,300,000 times higher than regular concentration of 0.001 Bq/km3, between March 14 to March 22, 2011. The amount of Xenon 133 has been decreased since then, yet in the mid-April, it still counted nearly 600 times more than the average prior to March 11. The data also included amounts of Krypton 85, Iodine 132, Tellurium 129, and Tellurium 132. The observation point is in Chiba City (about 40km/25miles east of Tokyo). The center says it does not check on Plutonium and Uranium.
I contacted the center to get more detailed numbers of the report since it only shows rough values on the graphs. According to our email correspondence, the center detected 48,000 Bq/m2 of Iodine 131, 53,000 Bq/m2 of each Cesium 134 and Cesium 137, and 1,000 Bq/m2 of Cesium 136 on the surface of graveled soil on April 14. The center also found contamination in the soil 5cm in the earth (the center does not check soils below 5cm in depth). It is shocking to me that such huge amount of Cesium 137 have been detected while the MEXT data shows the accumulated Cesium 137 of Chiba prefecture in about 5,000 MBq/km2 (=5,000 Bq/m2), 10 times less than the amount the center detected) from March 19 to April 24. 53,000 Bq/ms (=1.4 Ci/km2) of Cesium means the third contamination zone in the Chernobyl accident (1 Ci/km2 to 5 Ci/km2), where cases of cancer and leukemia abnormally increased after 10 years. It is assumed that the contamination level could be less by considering that most of the land was soil at the Chernobyl accident where most of the land in Japan are made by concrete. Nevertheless, proving the high detection of Cesium in Chiba prefecture means very serious conditions in Tokyo, Ibaraki, Yamagata, and of course, Fukushima and Miyagi, where they have detected more amounts of Cesium 137 by the MEXT's national data.
High Concentration of Plutonium Detected in the Soil 50km Outside of the Fukushima Plant: Food Manufacture Company who Detected is Reluctant to Release the Data to the Public
An article was released on May 14 regarding of high concentration of Plutonium detected in the soil 50 km outside of the Fukushima Nuclear Plant. It does not mention a place of the detection and a name of the food manufacture company. Here the article says,
"According to the food manufacture company, they do not want to disclose what they have found because they are afraid of the impact it would make in the public. They still detected high concentration of Plutonium from soil of rice field."
I want to urge them to release the data! We have been so suspicious anyways that the government has been determined not to check on Plutonium and Uranium, or I should say, that the government has been determined to conceal findings on Plutonium and Uranium. In either way, we have the right to know what is really going on.
Data on Other Prefectures
Gunma Prefecture: It has detected Iodine 131, 132, Cesium 134, 136, 137, Technetium 99m, and Tellurium 132.
Shizuoka Prefecture: It detected Iodine 131, Cesium 134, 137, and Potassium 40 in March. The total accumulation of detected Cesium 137 have been about 600 Bq/m2 from March 1 to March 31. According to the MEXT data, 120 Bq/m2 of Cesium 137 were detected from March 19 to March 31; therefore, the unreleased data on March 11 to March 18 could be assumed in 600 Bq/m2 minus 120 Bq/m2 = 480 Bq/m2 only in the first week after the earthquake.
*Thanks for those who have shared information with me, including the Japan Chemical Analysis Center.
ALL the Data of SPEEDI Really Disclosed?
The Japanese government pressured local governments NOT to disclose any findings by the System for Prediction of Environmental Emergency Dose Information (SPEEDI), but finally we heard the news that they decided to release the data to the public.
It only contains, however, information about the area surrounding the Fukushima Daiichi Nuclear Plant, and does not include any information we really want to know: how every radioactive materials predictably spread to country-wide and asia-pacific-wide level. The government is supposed to be equipped with the technology that could estimate the spread of each radioactive materials even to the areas of neighboring countries (which WSPEEDI and The Third Generation SPEEDI could do). So we cannot trust that this is the only available data.
Goshi Hosono, Prime Minister Naoto Kan's special adviser dealing with the nuclear accident and the secretary-general of the integrated headquarters said, "We have disclosed all the data of SPEEDI that the government received. I understand that no critical information could be obtained from the area outside of what is being observed (30km/18miles in radius from nuclear plant)." But it seems they made a mistake in their efforts to conceal other data, for Mr. Kosako, a biased scholar, left bombshell when suddenly resigned his position of Special Advisor to the Cabinet (probably he got scared to keep cooperating with government officials who set school safety standard that would kill many children. Kosako revealed that the government is still hiding data of WSPEEDI which covers much wider area. That is how we understand that the Japanese government conceals much more data. Then, again, government announced they will release hidden date from SPEEDI [e.g. data about amount of discharged radioculides when they did vents] This means they admitted they lied. Of course no one will forgive them. Because of information hiding, many people in Japan were deceived and unnecessarily exposed more to the radioactivity. Every person who involved in this decision of information hiding, as well as those who decided mass murdering standards, should be hauled to the court.
We, ordinary people, are asking for the truth, not information selected by nuclear industry or government or any sort of foolish excuse, like “we needed to prevent panic”. The government must more directly answer the question of which radioactive materials have been discharged at where, when, and how much from the Fukushima Daiichi Nuclear Plant. They have shown us only data of Cesium 137 and Iodine 131 (and now Cesium 134); monitoring is being done only at one location in each prefecture: there is missing data of a few days after the accident, which is when probably the largest amount of radioactive materials were emitted so far. U.S. has detected Plutonium, Uranium, Tellurium, Strontium, and Cobalt, but Japan does not yet disclose information on these radionuclides other than Iodine and Cesium. Hello, this matter is related to people's lives. Stop concealing vital information. Release all the data to the public immediately!!
