For your reading (dis)pleasure. The following quote sums it up:
"I'd rather take my chance [with anthrax]," she admits, "than the
government
take these measures without full disclosure."

An X-Rayed X-mas: Should the USPS Irradiate Your Mail?
J.A. Savage, AlterNet
November 5,
2001-------------------------------------------------------------------
Imagine if the fruitcake Aunt Emma sends you every year is, in 2001,
subjected not just to auntie's stove, but to an oven the size of a house
that zaps the poor loaf at 25 kiloGrays, delivering the radioactive
equivalent of 825 million chest X-rays to the X-mas cake. And you thought
it
tasted funky last year.
In response to the current anthrax-in-the-mail scare, the federal
government
has bought eight such irradiation devices, with an option for 12 more, for
the U.S. Postal Service (USPS). At $5 million per device, they are possibly
the USPS's most expensive attempt to quiet public fears about bioterrorism.
But will the devices actually make the public safer? Or will irradiating
our
letters, bills, catalogs, mail-order do-dads and holiday presents have
unintended health and environmental consequences, either in the long or
short term?
Unfortunately, the government isn't answering those question, or hardly any
questions at all, about mail irradiation. Unable to get such information,
consumer advocates and activists who cut their teeth struggling against
irradiated foods have filed a number of public information requests. On
Nov.
1, Public Citizen filed a Freedom of Information Act request asking for
copies of scientific studies used by the USPS to prove that irradiation
technology kills anthrax spores. The Nuclear Information and Research
Service (NIRS), also sent a formal letter to the USPS on Nov. 2, asking for
full disclosure on mail irradiation.
Among their concerns, according to NIRS Project Coordinator Cindy Folkers,
are what might happen if the irradiation process isn't fully effective. "If
spores are not destroyed with irradiation, mutation is risked," their Nov.
2
letter pointed out. As Folkers asks, "Might you end up with something worse
if you irradiate anthrax?"
In a testimony to Congress at the end of October, USPS Vice President Tom
Day referred to an armed forces microbiology study to support his claim
that
this irradiation technology kills anthrax spores, according to Wenonah
Hauter, director of Public Citizen's energy project, who was at the
hearing.
But Hauter said the study was neither peer-reviewed in the scientific
community nor published. "I just want to know how much radiation" will be
used, she added.
In Hauter's experience with food irradiation, a process similar to mail
irradiation, objects are bombarded with about 7 kiloGrays -- the equivalent
of 233 million chest X-rays. She believes the USPS machines, which use a
slightly different "e-beam" technology, would deliver 25 kiloGrays. Even at
that high level of irradiation, Hauter and Folkers question the devices'
efficacy for killing anthrax spores.
"There is not very much research out there," said Hauter, and what there
is,
she says, does not address the e-beam technology. What research Folkers
found indicated there is scientific evidence that water must be present to
have irradiation kill spores. But, she said, spores contain only 15 percent
to 20 percent water, while normal cells contain about 70 percent water.
"Radiation kills by breaking down water," she said. Hauter also claims that
e-beams only penetrate 1.5 inches through a package, so thick materials
with
spores on the bottom would not be sterilized, even if the technology does
work.
Titan Scan, the military contractor that is selling the e-beam units to the
USPS, did not return numerous calls for comment. Its major competitor,
Belgium-based IBA, would not remark on whether it was negotiating with the
U.S. government over selling its irradiation units. IBA did announce,
however, on Oct. 23, that its e-beam technology "can kill anthrax spores."
The American Postal Workers Union severely limited media interviews last
week, so there's no official word on workers' choice between the dangers of
anthrax inhalation or potential dangers from ionizing radiation. In the
current climate of anthrax fears, it's likely that postal workers would
choose the latter risk. However, if anyone may suffer from irradiation
devices, it would be USPS employees.
Most of the bad history with irradiation devices, including fatalities,
have
involved a technology that uses gamma rays as the source of irradiation,
not
the e-beam technology pursued by the USPS. But there are two instances of
workers in e-beam food irradiation facilities losing extremities in the
1990s, according to Public Citizen, and one instance in which two cancer
patients were killed when an e-beam irradiator used in cancer therapy
malfunctioned.
What might prove more hazardous to workers is the ozone given off by the
electron beam. "The long-term effect on lungs can be deadly," noted Hauter,
who added that the devices must have plenty of fresh air to minimize
exposure.
Like the fruitcake initially in question, ionizing radiation may alter more
than its intended target -- if it's going to try to kill a tough little
anthrax spore, it's going to have some effects on everything else it passes
through. NIRS, in its request for information from USPS, asked for details
on damage to film, computer equipment, magnetic media, scientific research
materials and blood. Public Citizen, in its Freedom of Information Act
request, added questions of e-beam's effect on pharmaceuticals, eyeglasses
and credit cards.
For certain, irradiation would make it impossible to ship certain products
through the USPS. Food items would have to forfeit any "organic" labels
after being zapped, which could be a major blow to the organic foods
market.
It is unlikely that seeds would be able to germinate after being passed
through an e-beam. And in its literature, Titan admits to color changes in
plastics as well as embrittlement. IBA admits there are side effects to
mail, but deems them "limited" and gives no details.
No one wants to be the target -- intended or unintended -- of biological
warfare. But in its hurry to protect the postal system, the government may
not be adequately addressing public concerns in the matter. Folkers, for
one, would rather have her questions answered than finding out 20 years
from
now about deadly long-term consequences of irradiated mail -- and she works
in Washington, D.C.
"I'd rather take my chance [with anthrax]," she admits, "than the
government
take these measures without full disclosure."
