WASHINGTON
– After years of internal deliberation and controversy, the Obama
administration has issued a document suggesting that when dealing
with the aftermath of an accident or attack involving radioactive
materials, public health guidelines can be made thousands of times
less stringent than what the U.S. Environmental Protection Agency
would normally allow.
The
EPA document, called a protective action guide for radiological
incidents, was quietly posted on a page
on the agency’s website Friday evening. The low-profile release
followed an uproar
of concern from watchdog groups in recent weeks over news that
the White House had privately agreed to back relaxed radiological
cleanup standards in certain circumstances and had cleared the path
for the new EPA guide.
Agency
officials had tried to issue the protective action guide during the
final days of the Bush administration in January 2009, but the
incoming Obama camp ultimately blocked
its publication in part due to concerns that it included guidelines
suggesting people could drink water contaminated at levels thousands
of times above what the agency would typically permit.
The
new version of the guide released Friday does not include such
dramatically relaxed guidelines in its text, but directs the reader
to similar recommendations made by other federal agencies and
international organizations in various documents. It suggests that
they might be worth considering in circumstances where complying with
its own enforceable drinking water regulations is deemed impractical.
Such
circumstances could include the months – and possibly years –
following a “dirty bomb” attack, a nuclear weapons explosion or
an accident at a nuclear power plant, according to the guide, a
nonbinding document intended to prepare federal, state and local
officials for responding to such events.
For
example, the new EPA guide refers to International
Atomic Energy Agency guidelines that suggest intervention is not
necessary until drinking water is contaminated with radioactive
iodine 131 at a concentration of 81,000 picocuries per liter. This is
27,000 times less stringent than the EPA rule of 3 picocuries per
liter.

原発事故時の核汚染－年間１ミリから２０ミリ許容へ－米国の環境保護庁新指針（案）
現在年間２０ミリシーベルトの避難基準を、１ミリまで下げるようにと政府と住民との間で何度も話し合いがもたれて
います。一方、日本の同盟国であり、世界最大の核大国である米国は原発事故などの長期に亘る放射能汚染が避けられない場合は、年間２０ミリまで被曝を認め
るように法律の改正を企てていました。
