Not a major contributor _anymore_. They certainly _used_ to be - eg:

somewhat wrong ;-)
As for matches, the context were that of match composition 30
years ago. The counter information was for a variety of matches that
haven't been produced in over a century.
I wouldn't consider that "just all up wrong".

During the 1950s and 1960s, the dangers of using radium was recognized
and it was phased out in the US. Instead, either non-radioactive
phosphorus compounds were used or various tritium compounds were used.
Other countries, especially third world countries, still use radium.
For example, Iraqi tanks captured during the Gulf War had radium dials

Phosphorus fluorescent paint from almost any printing shop. You can get
material called 3M Luminous film which is 9mil..
Ampco Manufacturing uses Phosphorus fluorescent paint for printing.
Give me a break. Do you think an artist points their brush with their
tongue when they're using oil paints? I'd tend to doubt that
radioluminescent paint came in flavors, and I'd presume that a watch
dial factory would have the facilities to provide a cup of water.
The working conditions are only part of it, and they are the most
easily addressed. The disposal problem is another factor.
Concentrating lethal materials for use in a specific application, where
it may be harmless, then having no concerns over the disposal of the
material is idiocy.
If you read the history of the women who got cancer from it, that really
is the reason they ingested it. They moistened the brushes with their
tongue, documented fact. I have no idea why they didn't use water. Ok do you
got a break, now go read the history of it and then you'll understand.
Do you just guess at things, or do any research? Try this little tidbit:
Radium Dial Painters
During the 1920s, the radium paint was applied to clock and watch
components in a variety of ways: painting it on with a brush, painting
it with a pen or stylus, applying it with a mechanical press, and
dusting. The latter procedure involved dusting a freshly painted dial
with radioluminescent powder so that the powder would stick to the paint.
The original practice of using the mouth to put a point on a brush is
described as follows by Robley Evans: "In painting the numerals on a
fine watch, for example, an effort to duplicate the shaded script
numeral of a professional penman was made. The 2, 3, 6, and 8 were
hardest to make correctly, for the fine lines which contrast with the
heavy strokes in these numerals were usually too broad, even with the
use of the finest, clipped brushes. To rectify these broad parts the
brush was cleaned and then drawn along the line like an eraser to remove
the excess paint. For wiping and tipping the brush the workers found
that that either a cloth or their fingers were too harsh, but by wiping
the brush clean between their lips the proper erasing point could be
obtained. This led to the so-called practice of "tipping" or pointing
the brush in the lips. In some plants the brush was also tipped before
painting a numeral. The paint so wiped off the brush was swallowed."
It might be worth noting that tipping the brushes was not something the
dial painters just decided to do. At least in some plants they were
actually trained how to do it. In fact, the instructors sometimes
swallowed some of the paint to show it was harmless. It has been
estimated that a dial painter would ingest a few hundred to a few
thousand microcuries of radium per year. While most of the ingested
radium would pass through the body, some fraction of it would be
absorbed and accumulate in the skeleton. Later on, Robley Evans would
establish a maximum permissible body burden for radium of 0.1 uCi.
As a result of the ingestion of the radium, many of the dial painters
developed medical problems of varying degrees of severity. The first
deaths occurred in the mid 1920s, and by 1926 the practice of tipping
the brushes seems to have ended.

Ignoring the potential health risks.
Just think of it. Some terrorist gets a bottle of fresh radium paint and
makes a dirty bomb. It may not kill or even injure anyone but the publicity
and panic in this day and age would be intense, especially if it in a public
place. (should be easy to clean up in the dark though)
Secondly, with controls on ionizing materials, how would one ship such a
material. Manufacturing of the radium isotope would also be highly
restricted today. You would need a license to handle it and be required to
be trained in HazMat to transport it.
Such a material would be very expensive due to all the regulations now
existing for its handling and storage and disposal (of material and
equipment so contaminated). Even if it were available to manufacturers (for
this purpose), it would be too expensive to justify given the many
alternatives in active lighting and phosphorescent paints.
does everyone realize the NSA has us all targeted as possible
Most chemicals cant be bought today by regular people for safety
while the exact same chemical can be bought from a swimming pool supply
Ahh that's what SMUGGLING can do for you. Seal it up in several layers
of plastic and immerse it in a steel can of chemicals of some other sort
bound for the USA. Easy to them get 25 gallons of the stuff, make 5
bombs that detonate in the AIR (altimeter based trigger, shoot them up
250 feet before exploding to get the maximum distribution).
