Discovery of radiation 'hot spots' in Tokyo sparks calls for decontamination standards - 19th Oct 2011

Officials have called for government standards on radiation decontamination measures following a spate of discoveries of radiation "hot spots" in the Tokyo metropolitan area.

On Oct. 2, a high radiation level of 3 microsieverts per hour was detected on a road in Tokyo's Setagaya Ward by a member of the "Setagaya Kodomo Mamoru Kai" (Setagaya Children's Protection Association), which was founded in June in the wake of the ongoing crisis at the Fukushima No. 1 Nuclear Power Plant. The member took measurements based on information on social media site Twitter. As it turned out, the radiation was coming from radium stored underneath the floor of a home in the ward.

At the time, Setagaya Mayor Nobuto Hosaka spoke of the difficulty in pinpointing hotspots, saying, "It's impossible for administrative officials to search everywhere. We want people to actively provide information to us in the future."

Tokyo's Adachi Ward detected a level of radiation of 3.99 microsieverts per hour next to the machinery room of an elementary school pool on Oct. 17, following measurements taken independently by a resident. However, the government has not yet provided any clear guidelines relating to decontamination work.

Based on the International Commission on Radiological Protection's limit of one millisievert of artificial radiation per year under normal circumstances, some local bodies have used a level of 0.25 microsieverts per hour as a guideline to determine whether or not to decontaminate areas, but the response varies between local bodies.

Tokyo's Arakawa Ward is the only one of Tokyo's 23 wards that has not taken its own radiation measurements. It has received reports from residents that there are hotspots with radiation measurements of up to 1 microsievert per hour, but ward officials have merely commented, "Safety was confirmed in measurements taken by the Tokyo Metropolitan Government in June."

Note:

During the Fukushima I nuclear accidents, three of the power plant's six reactors reportedly suffered meltdowns. Most of the fuel in the reactor No. 1 Nuclear Power Plant melted.TEPCO believes No.2 and No.3 reactors were similarly affected. On May 24, 2011, TEPCO reported that all three reactors melted down.

** Remember they hid the meltdown from the public for 2 months before admitting to it what else have they not said or will they wait for 2012 to release that information?

Chernobyl is still uninhabitable after 25 years and will mostly like stay that way for at least another 320 years, in Fukushima they have opened the schools, insisted it is safe but put a limit on outdoor activities as to not overexpose the children to too much radiation?

The former Prime Minister said it all in just a few words during radio broadcast:

Naoto Kan -- also contemplated evacuating tens of millions of people from in and around Tokyo.

“There was no clue about the amount of radiation coming from the Fukushima plant or if it was spreading over 100 or 200 kilometres.

“If that was the case, Tokyo would be in danger. And prime minister Kan actually said that eastern Japan might not be able to keep functioning; that it might collapse.”

Professor Matsumoto: talk of tens of millions ["30 million people"] being evacuated was dismissed, with fears it would cause mass panic and chaos worse than the nuclear crisis itself.

Collapse of Japan or Live with Nuclear Radiation? who decides this? and would they be truthful if it meant at least 30 million had to leave?
