We urgently demand the withdrawal of the Japanese Government's inhumane
decision to force 20 millisieverts per year (mSv/y) radiation exposure onto
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 millisieverts 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 20mSv/y is equivalent to 3.8microSv per hour measured outdoors.
3.8 micro Sv/h is roughly 6 times [the 0.6microSv/h] of "Radiation Controlled
Areas" (0.6 microSv/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 20mSv 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 micro
Sv/h or more). Further, roughly 20% of the schools fall within "Individual
Exposure Controlled Areas" (2.3 microSv/h or more) and are in an extremely
The level set by the Japanese Government at this time amounts to coercion of
this dangeroussituation upon children, and, can interfere with voluntary
measures by schools to minimize exposure.
MEXT states that 20mSv/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 Japanese government of the
- Retraction of the "20mSv/y" standard for children.
- Disclosure of the names of experts, who deemed "20mSv/y" for children to
At the governmental negotiation held on April 21st, it became evident that the
Nuclear Safety Commission (NSC) concluded the 20mSv/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 20mSv/year

standard ("Fukushima-Katastrophe - Japan legt hohe Strahlengrenzwerte fur
Kinder fest" or "Japan's MEXT sets High Exposure Limits for Children"), Der
Spiegel, April 21st, 2011.(See comparison to German workers.)

rise in the future. By setting these standards, the government will steer
clear of any liability legally, however not morally."
