radioactive metals being recycled
hello, all,
Below is a letter I am circulating to attempt to
influence the EPA. It is a little far afield of dioxin,
but relevant to us because it relates to human
health and democracy.
In essence, the EPA has proposed allowing
the nuclear industry to recycle all of their radioactive
and contaminated metal into the ordinary metal waste
stream. This would be a catastrophe for human health
as well as for the computer information infrastructure.
The letter below focuses on the latter, since talk
about the former seems to fall on deaf ears. (I'm certain
that it would not hurt if you modified the letter to make
health concerns.)
Thanks
Jon Campbell
ENVIRONMENTAL ACTION ALERT
COMPUTERS AT RISK
PLEASE READ AND SEND LETTER - SAMPLE BELOW -
TO THE EPA AND CALL DOE NOW
DEADLINE FOR EPA COMMENT IS OCTOBER 31!
(EPA email address is included below)
Greetings,
I am writing you to make you aware of a
Nuclear Regulatory Commission (NRC), Department
of Energy (DOE), and Environmental Protection
Agency (EPA) policy that threatens the
information infrastructure of the U.S. and the
manufacture of integrated circuits and PCs.
Several years ago, these agencies, prompted
by pressure from the nuclear industry, began to
promulgate regulations that would allow the sale
of radioactive metals from nuclear power and
processing plants to metal scrap dealers. The
agencies and the nuclear industry referred to the
process by which this would happen is to declare
that the radioactivity of these metals is "Below
Regulatory Concern" (BRC).
Without fanfare, the agencies have allowed a
limited amount of trade in radioactive scrap
metals, and about 40 scrap dealers and smelters
are currently involved in this practice. In
September, 1997, the EPA proposed putting these
rules into place for the entire nuclear industry
and the huge processing plants. If there is no
significant opposition to these regulations,
hundreds of millions of pounds of radioactive
steel and copper will ultimately enter the steel
and copper supply of the U.S.
The agencies' concern was almost completely
focused on health effects. Using statistics for
human exposure, the agencies set guidelines for
radioactivity levels for recycled metals or
products manufactured from them that would not
"significantly" affect human health.
Of course, government health risk estimates
virtually always underestimate harm, because they
do not take into consideration vulnerable
people (those whose immune system is weak or
suppressed), small children and infants, etc.
The entire "health risk assessment" scenario
and "cost-benefit analysis" is a rationalization
for Institutional Random Murder: deciding that
it is OK to kill a few random people to make (or
save) some money.
Furthermore, the vulnerability of modern
electronic equipment and particularly computer
chips and dense memory systems (e.g., hard disk
platters) to destructive ionizing radiation was
not discussed extensively. Such equipment is
billions of times more vulnerable to ionizing
radiation than biological species. Biological
systems have detection, rejection, and
replacement mechanisms for cells that are
damaged, as well as function replication -
typically thousands or millions of cells are
involved in identical cellular activity, so that
the death of a particular cell will not usually
significantly affect overall biological function.
(Multiple ionization damage to a single DNA chain
can cause cancer, but this is not the main subject of
this letter).
In contrast, most electronic circuitry is
not replicated, because there is an expectation
that if a set of components is designed correctly
and the chip is formed correctly that it will
continue to work, almost indefinitely. Component
dimensions and inter-component dimensions have
become sub-microscopic. Magnetic disk drive
densities are similar or greater. The 4-square-
inch CPU chips in common use today contain at
least 2 million individual transistors and many
times that in other components and
interconnections. A single 3" disk platter of a
high-density disk contains 100 million bits per
square inch.
It is already known that the damage to CPU
and other chips from cosmic ionizing radiation is
significant. The defects caused by ionizing
radiation are random. They could cause sudden,
dramatic, catastrophic failure, such as the
destruction of a CPU register. They could cause
subtle problems, such as incorrect floating-point
logic. They could cause hidden, invisible
destruction or modification of stored
information.
Once radioactive steel and copper are
introduced into the metal waste stream, both the
steel and copper and the foundries and smelters
will become contaminated. Machine screws,
batteries, internal wiring, chip wiring, plates,
chassis parts, tables, desks, filing cabinets,
keyboard drawers, and other metal components too
numerous to list all become potential sources of
destructive ionizing radiation.
Anything from steel fabrication hardware
used in chip manufacturing to reinforcing rod for
buildings might contain radioactive metals. Once
the floodgates allowing radioactive metals into
the waste stream are open, there is going to be
no way to clean up the mess.
The entire information infrastructure of the
U.S. is at risk, even now as a result of limited
allowance of this practice, and especially if it
is allowed on a massive scale. Not only are
computers themselves at risk, but the thousands
of intricate mechanisms that rely on the accuracy
of computers and embedded microprocessors, from
airplanes to tracking and guidance systems to
automobiles and pacemakers, are all vulnerable to
the threat of radioactive materials.
In late August, 1997, the U.S Department of
Energy (DOE) contracted with a company called
BNFL to recycle 126,000 tons of radioactive-
contaminated metal, including 6000 tons of
heavily uranium-contaminated nickel, from the
gaseous diffusion isotope separation buildings at
Oak Ridge, Tennessee. The Oil, Chemical, and
Atomic Workers (OCAW) has filed a suit to prevent
the contract from going forward, but their
concern regards worker safety and does not bear
on the extreme threat to computers and the
computer industry. (OCAW can be reached for
more information at 202-637-0400)
There is no way that BNFL can remove all the
radioactive isotopes from this material. The
nickel, in particular, was used for the gaseous
separation of uranium. The nickel is porous and
uranium-238, lodged in the pores of the metal,
cannot be removed. (Nickel is used in batteries
and in stainless and other high-grade steel.)
For modern electronic assemblies, there is
no such thing as "de minimus" (negligible)
radiation or radiation that is "Below Regulatory
Concern." Radioactive materials must be
completely isolated from the metal waste streams
if our information infrastructure is to survive
and thrive.
Below is a sample letter to John Karhnak of
the EPA, opposing this practice and demanding
that the radioactive metals already allowed into
the waste stream be tracked down and recovered.
Please sign and send a copy of this letter, or
one that you write based on the information
above, to Mr. Karhnak via email
(karhnak.john@epamail.epa.gov), or call him at
202-233-9280, or write him at the address below,
as soon as possible. The public comment period
for the draft regulations ends October 31.
The DOE/BNFL contract is referred to as the
"Oak Ridge Three-Building Decontamination and
Decommissioning Project." Please call Secretary
of Energy Frederico Peña at 202-586-6210 to ask
him to stop this project.

scrap program can be obtained at

benefit analysis is based on human radiation
hazards.

Center for Cleanup and Recycle (Mail Code 6602J)

U.S.EPA

Dear Mr. Karhnak,
This letter is in regard to the EPA program
for recycling and reuse of radioactive scrap
metal from U.S. nuclear facilities. As a computer
professional I am alarmed that you are
considering this program because of its potential
hazard to the U.S. information infrastructure.
Computer machinery - integrated circuits,
memory, and other components - are millions or
billions of times as sensitive to ionizing
radiation as biological systems. The latter have
complex detection, rejection, and replacement
mechanisms for cells that undergo damage from
ionizing radiation, as well as massive function
replication. Computer chips and components do
not.
I oppose any introduction of radioactive
metals into the U.S. metal waste stream, because
once it occurs, the entire metal supply is at
risk. It will be impossible to segregate non-
contaminated machine screws, copper wire, steel
cabinets, desks, and the myriad components that
make up computers and their environment. Not only
computers will be at risk, but all of the
machinery used in the U.S. that contains
computers and embedded microprocessors will be at
risk as well, from airplanes to pacemakers.
Furthermore, I have learned that a limited
amount of these radioactive materials have
already been released to certain waste handlers
and smelters. This practice must stop
immediately, and you need to locate, identify,
and recapture all that has been released thus
far.
In particular, the EPA must intervene to
cancel the contract between the Department of
Energy and BNFL to recycle 126,000 tons of
radioactive metal from the Oak Ridge gaseous
diffusion plant. The materials from this plant,
notably the uranium-contaminated nickel, cannot
be decontaminated sufficiently to protect
computer components.
This program is a serious danger to the U.S.
information infrastructure, and must not be
allowed to proceed.
Sincerely,
