The objective is called "ALARA", As Low As Reasonably
Achievable for
radiation. Generally in the workplace(General Population,
Whole Body) ,
more than 0.5 rems/year is restricted. People working in the
nuclear
industry are limited to 3 rems/quarter, or 12 rems/year or 5 rems/year
average.
We had a worker who used to store his dosimeter in the pencil cup
on his
desk...Along with his spare thoriated tungsten welding electrodes,
and this
caused me no end of grief and a paperwork nightmare with the NRC
until the
mystery was solved.
Beta radiation, most usually encountered with neutron treated materials
is
not as penetrating as gamma. The stolen Gold 198 that was
made into
wedding rings caused superficial burns on the customers, but no
other deep
organ damage.

Quartz,

I have not personally checked them from these sources.
Stones treated with neutrons can produce beta emissions. Usually
these
isotopes are short-lived and can sit and "Cool down" before
they are
shipped. One particular type of tourmaline can produce a longer
lived
manganese isotope that has caused problems.
Isotopes made in a reactor or by neutron irradiation are considered
'Byproduct" isotopes, and the NRC is really strict about their
licensing. The people who make smoke detectors had to jump
through a lot
of hoops to satisfy the NRC about the alpha sources used in them
(Americium
and Californium).
Irradiated stones will not be imported without an NRC Release, so
it does
not matter what countries or what local standards are used elsewhere.
The
NRC is generally a collection of nice people, but they have no sense
of
humor about certain things like activated consumer products and
stray
plutonium, etc.
Any Gieger type counter will detect Beta and Gamma. The most
expensive
models are not always the best for gemstone surveys. There
is a modestly
price one that has a long, semi-exposed tube running down one side
of it
that would be better for beta surveys than the more expensive Monitor
EC4,
that has a smaller, deeply mounted detector.
The excerpt below regards topaz, one of the most frequently treated:
(I bet I am not the only one who misses Mark Liccini! He could
rattle all
this off the top of his head!):
"1) Gamma Cells - exposure to a gamma ray source (60Co commonly
used) will
produce both blue and yellow color centers in some topaz, resulting
in a
brownish or brownish-green color. Subsequent heating removes the
less
stable yellow color centers without affecting the blue. Such treatment,
though once common, is not widely used today because it is not capable
of
producing the darker, purer blues that are in highest demand and
that can
be created by the other techniques described below. The light blue
color
produced by gamma ray treatment has been given the trade name "Cobalt
Blue". Darker blue stones that have undergone such a treatment
are often
grayish blue ("steely" blue). Gamma ray treatment is used
more often today
as a "pretreating" or screening process that can reveal
stones that are
more likely to be susceptible to treatment by the higher energy
techniques
described below; such stones will take on a bluish tint during this
initial
treatment.
2) Linear Accelerators ("linac" treatment) - topaz
exposed to high energy
electron beam. Process generates considerable heat; topaz is water
cooled
to avoid thermal shock and spontaneous destruction of color centers.
Process must be followed by heat treatment, as above, to destroy
the
unwanted, less stable yellow color centers. Result is typically
a deeper
blue stone (with little to no gray; trade name "Sky Blue")
than can be
produced by gamma ray treatment, but one that is radioactive for
a short
period of time. Such stones must be allowed to sit for a couple
of weeks in
order for the residual radiation to decline to safe levels.
3) Nuclear Reactors - topaz exposed to fast neutrons, producing
blue
color. No subsequent heating required. Color is typically a medium
to dark
grayish blue, sometimes described as "steely" or "inky".
Trade name for
this material is "London Blue". Heat treatment can be
used to lighten the
inky cast. Material treated this way is likely to be quite radioactive
and
may require several months or more of storage before the radioactivity
decays to safe levels. All material treated this way falls under
the
jurisdiction of the Nuclear Regulatory Commission; all producers
and
importers of this material must be licensed by the NRC.
4) Combination Treatments - treatments combining nuclear reactor,
linear
accelerator and heating to produce dark blue colors without the
"inkiness"
of the London Blue material. Trade names for this material include
"Electra
Blue", "Super Blue", "New Blue", "Swiss
Blue", "Max Blue", "American Blue",
"California Blue", and "Super Sky Blue".

Brasil apparently has only one irradiation Facility. It is in the
city of Sao Paulo and is called Embrarad. It is a Cobalt 60 Gamma
Ray
facility whose main activity is irradiating seeds and sterilizing
medical equipment and spices etc. Also some foodstuffs are irradiated
to preserve them.
In the past, White Topaz was irradiated at this facility to turn
it into
Blue Topaz. The cobalt 60 gamma ray irradiation will make sky blue
topaz
and some grayish London Blue colors. But the world market soon developed
a taste for many other variations of Blue Topaz and now almost the
entirety of all Blue Topaz irradiation of Brazilian Material is
done in
the USA in either Nuclear Reactors or Linear accelerators. The material
irradiated in the USA is subject to the strict controls on the level
of
residual radiation and the materials are held at the irradiation
facility until the government required maximum levels are reached.
One other material that has been irradiated in Brasil was beryl
to
produce Yellow Beryl (heliodor). But it was found that Yellow Beryl
required a very high level of gamma ray irradiation to turn it into
a
stable pleasant yellow color and it was subsequently found that
a linear
accelerator could do this job much more efficiently than the
installations in Brasil - thus again almost all of this material
is
being treated in the USA.
Recently Fluorite has been treated by the cobalt 60 gamma ray
irradiation to turn it into a Tanzanite blue color. This material
is
apparently being sold mostly in the orient.
According to a cobalt 60 gamma ray irradiation facility that I visited
in the USA, at the request of one of the Brazilian producers, -
the
gemstone material irradiated by this process has no residual radiation.
The representative of the facility demonstrated the safety of the
material by popping a recently irradiated stone into his mouth.

Hi Doug Turet & All,
REFER: Your post on ceramic laps in the Faceters Digest for January
11, 2000...
"and I've always gone back to Crystallite's isopropyl-and-wax
based formula,
which has never, ever (not even once, in over 10,000 stones) balled
up on me!"
Doug, I read your post with interest in the Faceter's Digest when
I was first
trying my hand at faceting. I have now decided to bite the bullet
and facet
stones harder than the quartz and garnet family. I intend to purchase
a Graves
Falcon ceramic lap and Jonathan's Batt lap. I was impressed with
your post. I
assume it means you have not been plagued with scratches when polishing
on
ceramic (as many have complained when using ceramic to polish).
Can you or any other of you list members tell me what suppliers
sell
Crystallite's isopropyl-and-wax based formula? What size diamond
grits do you
recommend to polish CZ and corundum on ceramic? Any tips will be
appreciated......

Hi All,
As always, THANKS! to everyone who offered insightful methods for
cabbing on
my Raytech. I decided to jump right in to get a "feel"
for it and first
cabbed a nice little Chrome Pyrope. I have a photo of the experimental
Pyrope cab, if anyone is interested... To cab the little begger,
I used
standard grinding and polishing laps. Grinding wasn't so bad, but
polishing...ha! Round stone, flat lap - do the math - it took me
forever!
But I was semi-patient. I was almost done when I decided to
refine a small
area on the girdle. That's when I learned: never allow the angle
of the dop
to fall beneath the parallel plane of the lap. The lap wrenched
my little
pyrope right off the dop and violently catapulted it across the
living
room.... 10 minutes later I found it, took a photo and plopped
it in a
baggy with the label "Experiment #1."
On the second experiment, I preformed and pre-polished using standard
laps,
but for polishing, I tried a suggestion from Gustavo Castelblanco.
I cut a
medium-thick piece of felt to fit my 6" master lap, and sandwiched
it
between the master lap and the polishing lap (ultra lap). Worked
great!!
We'd gotten some beautiful gel Sugilite in yesterday and I HAD to
cab a
piece before bed time. Awesome! The felt provides just enough
"give,"
providing greater surface contact between stone and lap, thereby
requiring
significantly less patience. A much better equation for me... :-)
I cut a
teardrop shaped, grape-purple, cabochon. When I get it off the dop,
it'll be
labeled "Experiment #2." A few more stones to improve
my symmetry and I'm on
my way.
Seriously considering writing a step-by-step ePub on the subject,
and taking
on a co-author (Frank Romano) to offer the Dremel method.
I'll post an
announcement if/when the doc is published...
Thanks again and best wishes to all of you for a healthy, happy
and
prosperous 2003!!

From: "Frank Romano" <romanfj@hotmail.com>
Hi, everyone!
I don't know how many of you read Discover magazine, but I just
found
something that's of interest to many of us on the list. My
December issue
contains an article titled "The Next Photography Revolution",
if anybody
wants to go get a copy later. The short version, in layman's
terms, is that
a new kind of color sensor called the X3 has been developed in which
each
"pixel" can "detect" all 3 primary colors, as
opposed to current digital
camera sensors that are only able to detect and interpret one at
a time.
Thich results in some amazing pictures, some samples of which are
in the
article. Their quality, as shown in the magazine rivals that
of the $2300
Nikon F5, a conventional 35mm.
The only camera currently made using this technology is manufactured
by
Sigma (the SD9 model) which is currently supposed to sell for $1800.
Better gem photos are on their way!

PS Anybody out there decides to get one of these babies after
the price
comes down a bit that already has a Nikon 900 and wants to unload
it, drop
me a line :-)

Hi Thurmond. The attached is about a dear friend and his wife from
the 27
years we wintered in Florida(from Canada) He was my mentor and Faceting
teacher and had the privelege of using a good deal of his equipment
and
buying tumbling rough and equipment, a couple of faceting machines
etc
etc. Am in a retirement home, still faceting some at 88 and off
course
biased about Bill Harris but in no way associated with his business.
It
would take too long to list the details of Bill's business but for
instance he was Graves west Fl. agent, Distributor for Raytech
industries for Florida. A Goldsmith, Silversmith,-- all the Faceting
and
Lapidary Arts teacher andsupplier.
What I would like to see is his notice
placed wherever you might
think appropriate in The Digest. Also a web site is being prepared
which
I will forward when I hear it is ready. Hilda his wife is the one
to
communicate with as Bill is totally deaf.
Happy New Year to you and as usual I will
await tomorrow's Digest!!
Jack Denne.

TODAY'S FUNNY ~
A minister and a lawyer arrived at the pearly gates. Saint Peter
greeted both of
them and gave them their room assignments.
"Pastor, here are the keys to one of our nicest efficiency
units," said St. Peter.
"And for you, Mister Lawyer," smiled St. Peter, "the
keys to our finest
Penthouse Suite atop our Heavenly High Rise Building with all the
amenities. The
expansive windows offer a beautiful view of the Angels as they come
and go. If
you need anything, feel free to push the service buzzer!"
"This is unfair!" cried the Minister.
"Listen," St. Peter said, "ministers are a dime a
dozen up here. This is the
first Lawyer we've ever seen!"

COMPETITIONS:
For All National and International Masters, Past-Masters and
World-Class Cutters:
This post is simply a reminder that in 2003 the USFG will host its
first National and International Faceting Competition. It
is called
the North American Faceting Challenge -- 'NAFC.'
Since the designs
and rules were first published in the 2001 September Issue of
the
USFG's Newsletter, and since they have not been published since
2001,
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten.
The
"NAFC" is an OPEN Competition. Please note:
The designs and rules
can be downloaded at <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003; the amount of time between
the
present date and June 20th, 2003 should be enough for all Master
cutters to cut the two required designs -- Fred Van Sant's "Four
Star," and Charles Covill's "Wind Wheel No. 2."
If further
information is needed, please contact me at <clmoon@pacbell.net>.

First USFG faceting list design competition.
Design: Hexagon or Hexagon Cushion in Colorless or Colored
Topaz
Judging: Highest number for total ISO values at 0, 10, 20,30, 40
and 50 degree tilt with five degree head shadow in GemFramx will
win. Example parameters are given below to achieve this configuration.
Online designs must be submitted by January 10, 2003. Design and
cut entries should have the design posted by that date but stone
judging
will take place at the OPLC Hobnob in Tucson in February 2003.
Publication: All entries will be posted on the USFG faceting list
site
and possibly on the USFG site as well. Designs may be included in
a USFG list CD. Designers maintain copyright to their designs but
must allow posting on the USFG faceting list site. Posting or publishing
elsewhere is not only permitted but encouraged.
Followup: Additional contests may be held for other shapes and
materials if there is sufficient interest and participation.

points deducted for a missed meetpoint. Fractional
Special recognition will be given to most original design as determined
by team of four judges selected by Jeff Ford or delegate/s.
Classes:
Individual,
all work must be done by one individual. In the
case of a fractional indices or an incomplete design a design
coach will explain how the problem can be fixed and the
entry will be moved to Coached class.
Team/Coached,
more than one individual from a club, guild or area may work together
as a team. If an individual wishes coaching they may do so
but most
work must be done by the entrant with only suggestions by coach.
This
means Fred Van Sant or some other designer can not do a design that
you
enter as your own. I encourage friends, club/guild members to enter
as a
team. Do not hesitate to enter if you need some coaching. We have
design
mentors who are happy to help you.
Modified,

holder
gives you permission to use. You enter design with modified angles,

or deleted tiers which gives "optimum" performance as
determined by ISO
total. We will post at least two very basic designs you can enhance
as you
please.
Design and Cut,
design will be posted and ISO Total noted but beauty of the finished
stone
will be the judging criteria. Stones will be judged at the OPLC
Hobnob in
Tucson. Individual, Team/Coached and Modified designs will be judged
separately.
I hope this format will encourage design and optimization
oldtimers and
newcomers to get involved and hopefully develop their skills. All
entries will be posted on the site and may drive some traffic and
interest.
I think ISO Total is as good as any single value to evaluate design
performance but we will look to improve criteria in the future.
