Dear Group:
The McArthur River uranium mine is an Upper Proterozoic (Pre-Cambrian)
Unconformity-Related deposit of the Argillite type in the Athabasca Basin of
Canada. It contains 436.5 million pounds U3O8 with an average grade of
24.7%.
The Proterozoic Unconformity represents a world-wide atmospheric / climate
change from reducing to strongly oxidizing conditions with the appearance of
free oxygen in the atmosphere. The deposits occupy zones slightly above, at,
and below the unconformity. The argillite (clay) protected the McArthur
River and Cigar Lake deposits and is above the unconformity. Deposits and
prospective targets are located world-wide with significant deposits located
in Australia (Alligator Rivers) and Canada's Athabasca Basin.
The McArthur River deposit is mined using a freeze-wall curtain to control
water influx, and large-diameter, raise-bore methods to mine the ore.

If there are any neutron instrument gurus out there that would like to
check this instrument out, I have the following information for you:
"We are looking for a nationally known Health Physicist that can spend a
day at our facility to critique our instrument, review our technology and
calibration data, check the dosimetry calculations, and give us

I suggest that the company try contacting the radiation control agency
responsible for the jurisdiction they operate in. The agency (state or NRC)
might be willing to send over an HP to check out the system, and they may
have access to neutron sources and detectors that would be useful for
evaluating the spectrometer. Remballs and the like are uncommon among most
instrument inventories, but regulators usually have them. Can't hurt to
ask.

Someone got their math mixed up in this article. It should to 50,000 TONS
of ore mined in a year.
Digging deep: Uranium mine at McArthur River presents challenges like few
others
The StarPhoenix (Saskatoon) Fri 29 Sep 2006
Byline: Murray Lyons
MCARTHUR RIVER MINE -- In the underground workings of the world's
highest-grade uranium mine there are few signs that a huge influx of water
put the place out of commission for three months in the spring of 2003.
<SNIP>
The remotely-mined uranium ore at McArthur River averages 24 per cent pure
uranium, with hot spots that can soar as high as 80 per cent. If the mine is
going through a section of ore that is ultra high grade,
operators have to add scoops of waste rock to the SAG mill to blend down the
product, Rheault says. Uranium is one of the heaviest elements on the
periodic table and it would not be possible for the
uranium to be pumped as a slurry to the surface at such high grades if it
wasn't blended.
No one can explain with certainty why McArthur River's geology has such high
grades. However, Haywood explains the mine's ore grade is 100 times greater
than the average uranium mine. Some rock below two per cent uranium, which
would be considered high grade anywhere else in the world, is considered
waste rock at McArthur River and is used
only for blending purposes, he says.
All told, McArthur River is one of the trickiest ore bodies in Canada,
managing safely with both the water issues and the radiation issues raised
by such high grade ore. Haywood is anxious to point out the
remote mining methods and high volume of air pushed through the workings
means workers are exposed to only about one extra millisievert of radiation
annually. Canadian Nuclear Safety Commission regulations allow a worker to
be exposed to an annual level 50 times that, a company presentation says.
With 24 per cent uranium content ore, the mine can hit its licensed capacity
of 18.7 million pounds of uranium each year by mining an average of 150 tons
of ore a day.
"That's the beauty of having high grade ore," Haywood says. "At the world
average uranium grade, more than five million tons of ore would have to be
mined each year, whereas we only mine about 50,000 pounds of ore."

The Times reports Seizures of radioactive materials fuel 'dirty bomb' fears
http://www.timesonline.co.uk/article/0,,2-2391574,00.html
SEIZURES of smuggled radioactive material capable of making a terrorist
"dirty bomb" have doubled in the past four years, according to official
figures seen by The Times.
Smugglers have been caught trying to traffick dangerous radioactive material
more than 300 times since 2002, statistics from the International Atomic
Energy Agency (IAEA) show. Most of the incidents are understood to have
occurred in Europe.
The disclosures come as al-Qaeda is known to be intensifying its efforts to
obtain a radioactive device. Last year, Western security services, including
MI5 and MI6, thwarted 16 attempts to smuggle plutonium or uranium. On two
occasions small quantities of highly enriched uranium were reported missing.
All were feared to have been destined for terror groups.
Scientists responsible for analysing the seizures have given warning that
traffickers are turning to hospital X-ray equipment and laboratory supplies
as an illicit source of radioactive material.
Investigators believe that the smugglers, who come mainly from the former
Eastern bloc, are interested only in making a swift fortune and believe that
they may have no compunction in selling to jihadist groups. Most undercover
operations and recent seizures have been kept secret to protect the
activities of Western security services.
Rigorous controls on nuclear processors, especially with Russia co-operating
to stop the trafficking of enriched plutonium and uranium, have limited
smugglers' access to weapons-grade nuclear materials. But medical and
laboratory sources, including waste, remain vulnerable. Such radioactive
waste can be used to make a dirty bomb.
A dirty bomb combines a conventional explosive, such as dynamite, with
radioactive material such as spent nuclear fuel like highly enriched uranium
and plutonium. In most instances the conventional explosive would kill more
bystanders but the dispersion of the radioactive material would have a
hugely damaging "fear" factor.
There were 103 cases of illicit trafficking last year, compared with fewer
than 30 in 1996. Fifty-eight incidents were reported in 2002, rising to 90
in 2003 and 130 in 2004. Experts point out that seizures in the past three
years equal the same amount of trafficking in the previous seven years.
Olli Heinonen, deputy director-general of the IAEA, which monitors
trafficking and inspects nuclear plants to audit their radioactive
materials, said that while weapons-grade nuclear material smuggling was now
rare there were serious concerns about other radioactive substances.
"A dirty bomb is something that needs to be taken seriously. We need to be
prepared for anything because anything could happen," he said. "Terrorists
look for the weakest link. We need to be alert and we need to be prepared."
Al-Qaeda makes no secret of its desire to obtain a dirty bomb. Last month
its leader in Iraq, Abu Hamza alMuhajer, called for scientists to join it
and experiment with radioactive devices for use against coalition troops.
Even before 9/11, Osama bin Laden invited two Pakistani atomic scientists to
visit a training camp in Afghanistan to discuss how to assemble a bomb using
stolen plutonium. Captured al-Qaeda leaders have since confessed to the CIA
of their attempts to smuggle a radioactive device into the US.
Professor Klaus Lützenkir-chen, who helps to analyse the seized substances,
said that even small quantities of radio-active material could be of use to
terrorists.
"If someone gets hold of it, it is possible it could be used in a dirty
bomb," he said. He added that if such a dirty bomb were detonated in a town
centre the physical effect would be comparatively small and unlikely to
cause huge loss of life but would have an enormously damaging "fear factor".
One of the most serious seizures since 9/11 was that of several kilograms of
a radioactive substance known as yellow cake that was found in a consignment
of scrap metal at the port of Rotterdam in December 2003.
Professor Lützenkirchen said that seizures have been made across Europe,
usually at borders and sea ports. Most of the trafficked material originated
from the Caucasus region where he said that there was "considerable
activity" among smugglers.
Seizures have continued this year, though overall figures for 2006 are not
yet available. They include the discovery in Germany of a small quantity of
highly enriched uranium.
* High-level representatives from the US, Britain, France, Germany, China
and Russia will meet today in London, where they are expected to refer the
Iranian nuclear case to the UN Security Council after a defiant Tehran
refused to suspend uranium enrichment.

Dear radsafers
I need your opinion and experience.
1) Do you think that a regular nuclear medicine laboratory which uses only
ready for use in vitro RIA kits performs any kind of iodination?
As I know the iodination process is performed only at pharmaceutical
industries in order to produce "ready to use RIA kits".
2) I would like to have your definition of the "iodination" term from the
radiochemical point of view.
3) From the practice (or legislation) in your countries, Do you believe that
a private in-vitro nuclear medicine lab which uses only "ready to use RIA
kits" can not by established at buildings which includes other offices or
flats or apartments.?

Reassembly of shattered chromosomes in Deinococcus radiodurans
Deinococcus radiodurans is able to withstand high doses of radiation,
despite the DNA damage caused.
Genome fragments with regions of complementary sequence meet and initiate
synthesis by a DNA polymerase
to form long single-stranded ends on the fragments. The complementary
single-strand tails then pair
and regenerate long double-stranded DNA molecules that are processed into
the original circular genome.
