Anti-depleted uranium activists have enlisted the assistance of all of Hawaii’s leftist alternative weeklies in a campaign against depleted uranium. The Hawaii Island Journal June 30 caries a front page cartoon skeleton in an aloha shirt and the headline “Radioactive us -- danger depleted uranium.” Articles on the alleged risks of depleted uranium appeared in quick succession in Honolulu Weekly, June 13, Maui Time, June 21, and Big Island Weekly, June 27 as well as the Journal.
Big Island Weekly points out that the latest anti-DU hype is based on observations in South Kona by an activist armed with a $399.00 “Gamma Scout,” Geiger counter. Allegedly the readings of “63 counts per minute” cited by Big Island Weekly indicate that “we might have a Gulf War in our backyards” and underlines “suspicion that DU is being used on Hawaii.”
As usual, the truth lies elsewhere.....

“63 counts per minute” ?..........In a volcanic area?.........
Depleted is a funny word. I wonder what it means?
All I know is that depleted Uranium in 23mm increments, comming at you at 2700 fps is not a good thing.
Depleted no longer means “Depleted”

It seems to mean “propaganda”
Obviously it means “full of crap”............They must have had the probes stuck up someplace that’s dark and smells bad.......

This is hype.
But, that said, DU is about a third as radioactive as natural uranium and prone to corrosion so I would rather not have it around me.
BTW, I’m sure there is DU in South Korea - since the Soviets starting using it in 70’s most nuclear power use it either for armor or kinetic penetrators.
I wonder if these folks know that there is radiation all around us 24-7?..........Lead is just another form of “depleted” uranium.........
Typical; you could probably sell the pregnant women there an antiabortion pill and they’d all rush out to buy it.
the heavy-metal itself is plenty toxic, without considering radioactivity or “depletion”
Is there an MSDS sheet for it?
63 CPM! LOL! We’re all doomed.
My Ludlum 3-90 is showing about that much at my deak.
1 mCi Co-60 is 37,000,000 decays per second. That amount at 1 meter away gives an exposure of 1 mR/hour.
They get more “radiation” from their microwaves than from DU...........

Subject: Radon gas in Hawaii
Is radon gas a problem in Hawaii, particularly on the big island? What causes radon gas to occur?
In answer to your questions about radon gas, “no”, it is generally not a problem for most of Hawaii. I suppose the best way to explain this is to first explain where radon gas (abbreviated as “Rn”) comes from and how it can accumulate to hazardous levels in some areas.
Rn is a radioactive gas produced by the decay of uranium. Uranium (U) occurs naturally in most rocks and natural waters, and it is the isotope 238U that decays through a series of daughter elements to Rn. The half-life of Rn is only about 3.5 days, so for it to remain at high levels in a natural system, it must be continually produced from its immediate parent isotope, 226Ra (the latter of which is also a daughter of 238U). Radon itself decays to make another radioactive isotope of the element Polonium which in turn feeds a chain of six main additional radioactive isotopes before the radioactivity stops at stable lead (Pb) 206. The longest-lived intermediate daughter isotope of Rn is 210Pb, which has a 22 yr half-life.

the activist is taking reading while standing next to their
smoke alarm
Well, hell, the "mainstream" newspapers here are truly liberal fringe already: Honolulu Advertiser and Star Bulletin. No need to use the minor papers to get the wacko word out.
It means that most of the U235 has been removed from it. Natural uranium is a mixture of about 99.3% U238 and 0.7% U235. Enriched uranium with higher proportions of U235 is used for reactor fuel or nuclear weapons. The depleted uranium is almost all U238 which has a half life of 4.5 billion years. Since radioactivity is inversely proportional to half-life, depleted uranium is not very radioactive at all, and it can't be used to make fuel for conventional nuclear reactors. It's the daughter products of U238 decay that can be a problem.
Depleted uranium a really good material for making armor due to its density which is about double that of lead. It also is an excellent material for making armor penetrating rounds due to both its density and the fact that it is self sharpening as it penetrates.
probably, but then there aren’t very many uses for Uranium, “depleted” or not. All I mean to say here is that U is toxic in the same way berrylium (sp?) is.....I happen to know that when berrylium parts etc are being deburred, the grinding wheel and the part must be underwater and the operator must wear a mask and gloves to prevent inhaling or absorbing the dust.
As for the “DU” rounds sometimes used by our military (most often against heavily armored stuff).....I doubt that it is very radioactive at all......if it were, it would set off all the sensors and alarms, falsely indicating a radiological release or attack. So in that way and for that reason, I’m satisfied with what DoD says about it.
I see that you’ve read some and probably a lot more than I have about it.
You, my good man, are exactly dead-on right.
The radiation level of DU is low. It is an alpha-particle emitter. Alpha radiation is the weakest kind and can be blocked by a sheet of paper or by your skin.
The worst case scenario is if you ingested or breathed in the DU. If you somehow snorted a whole kilogram of DU up your nose the total radiation dose would be about 1 millisievert, the equivalent of two chest X-rays.
Got any red Fiestaware from the 30's or 40's? They used uranium dioxide to give the glaze that color. The old plates will still get a counter buzzin'. :)
It makes excellent dart barrels, too. Easy to machine and very dense.
sometime in the distant past, I read about the Ladies who painted radium onto compasses, timepieces, and ship/aircraft instrument panel gauges so they would glow in the dark and be visible without lighting up our guys unnecessarily with lighting........the Ladies found that they could do a much nicer job if they wet the artists paintbrushes with spit to keep the tiny bristles in line as they became raggedy......the radium made nearly all of them very sick over time, and it was too late for a lot of them by the time this was learned.....these Ladies were some of the “Rosie the Riveter” type gals.......sad story.
Concerns circulating Hawaii County about possible depleted uranium at Pohakuloa Training Area on Mauna Kea are likely the reason Big Island residents have taken to purchasing radiation monitors, a Department of Health official says.
But a lack of training in how to use the monitors, as well as the use of older models and uncalibrated machines, is leading to weekly calls to the department and a false alarm, like one Sunday in the Kona District, said Noise, Radiation and Indoor Air Quality Branch Program Manager Russell Takata.
“It was an unnecessary alarm,” Takata said of the incident, which he learned of at about 2 p.m. Sunday.
A Kona resident,(read: anti-war moonbat hippy) using a radiation monitor, recorded high levels of background radiation and reported the incident to the Department of Health. Takata contacted the Fire Department, whose hazardous materials teams took their own readings. Those readings showed normal background radiation levels, well within the federal standards for radiation. Such calls originating on the Big Island are becoming more common, as more residents purchase radiation monitors but don’t have the scientific training to use or correctly interpret their findings, Takata said.
Those incidents, and requests from residents for basic training about radiation levels, radiation sources and how to use the monitors prompted Takata to offer an educational session last week in Hilo and on Saturday, Aug. 11, in Kailua-Kona.
“The first thing is understanding what constitutes radiation,” Takata said. “Apparently there’s a big fear that any high background might be depleted uranium from Pohakuloa Training Area. That’s not true.”
The training session, which is scheduled to last about six hours at King Kamehameha’s Kona Beach Hotel, will also present information about radiation, natural sources of radiation and how much radiation exposure people get daily from natural and medical sources, Takata said.
He also claimed that monitors might register higher radiation counts from land devoid of vegetation, like some areas off Saddle Road near the Army’s training area.
“It’s kind of wind-swept,” he said. “You get a lot of dust kicking up. You’ll get a little higher background reading.”
Because of space limitations, Saturday’s session, which is free, can accommodate about 25 people. Takata asked anyone planning to attend to e-mail him at Takata at russell.takata@doh.hawaii.gov or to call the Department of Health at (808) 586-4700. If more than 25 people are interested in the session, Takata said he would schedule another for a later date.
- but then there aren’t very many uses for Uranium -
I was TDY to Charleston Air Force Base back in the early 80s and was visiting the Chief of Safety who was a good friend of mine. He showed me some photos and such of a C-141 crash in the mountains nearby which had to be cleaned up because the counterweights on the elevators were made out of DU.
I have no idea if it is used in commercial aircraft or in any other DoD planes, but at least they had found a use for it other than for penetrating armor.
Lot’s of stories like that. Radium rods inserted in sinuses to “cure” adenoids, radium soppositories to shrink hemmoroids, and the ever cool fluorscopic shoe fitting machines.
I remember a Starliner going down in the States about then.
I got a very long ride in one once, we were facing east, but going west, with only one pitstop at Wake. A bus would have been as miserable, LOL. I was permanent party in a Pershing unit at Ft Sill for a few months in early 67 after AIT; most of which was actually spent near Blanding on Black and White mesas with a W German Army Pershing unit.....6 or 8 rounds total. I witnessed some awesome stuff, but my MOS was unrelated.....(noticed your tagline).....
True, but it can be used in breeder reactors to be bred into plutonium. I believe that some day we'll wish we hadn't treated it as a waste product, but had saved it for breeder reactors.
With a half-life of 4.5 billion years, I believe there will be some around, if not we can get it from the astroid belt.
I HATE Jimmy Carter.
Really, truly, hate, loathe, despise ... he was a worse President than X42.
Well the expended shells could be mined and recycled as DU.
Not until my DC tour was I able to visit overseas. Did some work at the policy level then and saw some nice countries while performing said functions.
I have another friend who was a 141 pilot and I was allowed to accompany him on a special night mission training flight consisting of three 141s and absolutely no lights inside or out. I got to stand near the back with the rear doors open while the crew chief extracted training “cargo” out the back at 800 ft AGL. Seeing two other aircraft illuminated by only the moon behind us only about 1000 ft apart was quite awesome.
