Urgent Petition Against Imposing 20 milli-sievert Radiation Exposure Standard onto Children in Fukushima

Urgent Petition Against Imposing 20 milli-sievert Radiation Exposure Standard onto Children in Fukushima
[Date will be date of submission: April or May 2011]

[Emergency Statement and Demands]
We urgently demand the withdrawal of the Japanese Government’s inhumane decision to force 20 milli-sievert per year radiation exposure onto children.

Sign the petition

Preliminary deadline: Tue. April 26, 2011 at 23:00 Japan time
(UTC/GMT April 26th 14:00)
Final deadline: Sat. April 30, 2011 at 23:00 Japan time (UTC/GMT April
30th 14:00)

On April 19th, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) notified the Board of Education and related institutions in Fukushima Prefecture the level of 20 milli-sievert per year (mSv/y) as a Radiation Safety Standard for schools in Fukushima Prefecture. This is the standard to be used for school grounds and buildings. The Government has indicated that 20 mSv/y is equivalent to 3.8 micro-sievert per hour (μSv/h) measured outdoors.

3.8 μSv/h is roughly 6 times the standard for “Radiation Controlled Areas” (0.6 μSv/h or more). The Labour Standards Act prohibits those under the age of 18 from working under these conditions. Forcing children to be exposed to such radiation doses is an exceedingly inhumane decision. Therefore, we condemn this in the strongest terms.

20 mSv/y is comparable to the [legally] recognized dose for inducing leukemia in nuclear power plant workers. It is also comparable to the maximum dose allowed for nuclear power plant workers in Germany.

In addition, this 20 mSv standard [for Japanese children] does not take into account the fact children have higher sensitivity to radiation than adults, nor does it take into account any internal radiation exposure.

Currently, according to the radiation monitoring conducted at elementary
and middle schools within Fukushima Prefecture, more than 75% of these
schools have contamination levels comparable to “Radiation Controlled
Areas” (0.6 μSv/h or more). Further, roughly 20% of the schools fall
within “Individual Exposure Controlled Areas” (2.3 μSv/h or more) and
are in an extremely dangerous situation.

The level set by the Japanese Government at this time amounts to coercion of this dangerous situation upon children, and, can interfere with voluntary measures by schools to minimize exposure.

MEXT states that 20 mSv/y is based on the recommendation Pub.109 by the International Commission on Radiological Protection (ICRP) as well as on the reference levels in the band of 1 to 20 mSv/y as “Post Emergency Situation” Standards from the ICRP statement released on March 21st. The latter means MEXT has adopted the maximum level.

As of March 21st, there has been no substantive information disclosure by the Japanese Government on the decision-making process for establishing these standards. Moreover, no explanation has been given concerning why the Government has neither taken the sensitivity of children into consideration nor internal radiation exposure into account. The contents of the consultation held between MEXT and the Nuclear Safety Commission (NSC) are not disclosed, and the situation remains extremely opaque.

We demand the following of the Japanese Government:
-Retraction of the “20 mSv/y” standard for children.
-Disclosure of the names of experts, who deemed “20 mSv/y” for children to be safe.

At the governmental negotiation held on April 21st, it became evident that the Nuclear Safety Commission (NSC) concluded the 20 mSv/y standard for children as “permissible” without undertaking any formal consultation. Moreover, on April 22nd, the Commission reported to the office of Mizuho FUKUSHIMA, member of the Japanese Diet, House of Councillors that no minutes (records) exist of the 5 Nuclear Safety Commission members’ deliberation leading to the 20 mSv/y standard.

“The cancer risk will visibly rise in the future. By setting these standards, the government will steer clear of any liability legally, however not morally.”

    You can get the information you need by consulting a representative of the insurer that provides the vehicle cover or you can also consult the internet to find out which models are covered in your area.
