New data show massive radiation levels in Odaka, Minamisoma

We are presenting here the most recent soil contamination map made by the “Environmental Radioactivity Measurement Project around Fukushima Daiichi Nuclear Power Plant.”

The area where measurements took place is shown by a green square in the map.
It includes two administrative units, Hanokura and Otomi of the Odaka district of Minamisoma town of Fukushima prefecture.

Here is the soil contamination map.

Taro Yamamoto of the Liberal Party, member of the House of Councilors, used another map prepared by the same group on two other administrative units of Odaka district during his questions at the Special Commission of Reconstruction of the House of Deputy on November 18th 2016.

We are quoting here some extracts of his questions *.

You are well aware of the existence of the Ordinance on Prevention of Ionizing Radiation Hazards. This is a rule that must be respected in order to protect workers exposed to risks related to ionizing radiation in establishments such as hospitals, research laboratories and nuclear power plants, isn’t it?

It contains the definition of the Radiation Control Zone. This is Article 3 of the Ordinance in File No. 1. It states that if the situation corresponds to the definition described in Article 3/1 or to that specified in Article 3/2, the zone shall be considered as a Radiation Control Zone and a sign must be posted there. I will read parts 1 and 2 of this article.

1: The area in which the total effective dose due to external radiation and that due to radioactive substances in the air is likely to exceed 1.3mSv per quarter – over a period of three months! When the dose reaches 1.3mSv over a period of three months, a zone is called a Radiation Control Zone.

Part 3/2 refers to the surface density in the attached table. Here is File No. 2. What will it be if we do the conversion of the density of the surface per m2?

Government expert (Seiji Tanaka) The conversion is 40,000Bq/m2

In the town of Minamisoma in the coastal region of Fukushima Prefecture, three types of evacuation zones were established after the earthquake. In July 2016, the evacuation order was lifted in the “evacuation order lifting preparation area” and in the ‘’not-permitted-to-live area’’. There is only one household with two people remaining in the “the difficult-to-return-to area”. According to the State, 90% of the territories of Minamisoma are safe.

There is a group called “The Measurement of Environmental Radioactivity Around the Fukushima Daiichi Nuclear Power Plant*** ” composed mainly of residents of Minamisoma. Since 2012, its members have been taking measurements of soil contamination in the vicinity of the members’ neighborhoods and in residential areas. They provided the information. Please take a look at File No. 3. You see a colored map.

This is the map of soil collected and measured in the territories where the decontamination works have been completed. The colors show the levels of contamination. The blue colored area indicates where the contamination measurements are below 40,000Bq / m2, ie below the level of a radioactivity controlled zone. There is only one, at the bottom right. Apart from this one, at all other places, the colors show measurements equivalent or higher than in a Radiation Control Zone. There is even an area colored gray where the measurements exceed 1,000,000Bq / m2. There are people living there!

END OF QUOTE

The evacuation order is already lifted from Odaka district of Minamisoma town, and officially the decontamination work has finished. However, the two maps show that in wide areas highly radioactive soil is being found. Their measurements are well above the lower contamination limit of a Radiation Control Zone.

In a Radiation Control Zone, following the Ordinance on Prevention of Ionizing Radiation Hazards, it is prohibited to drink, eat or stay overnight. Even adults are not allowed to stay more than 10 hours. To leave the zone, one has to go through a strict screening.

How can people live there?

The policy to make a population return and live in areas even more contaminated than most of the Radiation Control Zone, while cutting the financial and housing aid for evacuees, is a serious infringement of human rights.
