Well, not her. She's obviously one of the few that are telling the truth as David sees it.

You've been told about that.
Why can't you just summerize what's in the video, and only use the link as a reference?

You're not practicing good debate tactics.

Frankly I can't be bothered watching a 40 min video when the OP can't even be bothered with making a point about his conclusions around the topic in the video.

This thread reminds me of a job I had at college. I was charged with retrofitting used computers for students to rent during the year. Parents and their freshman kids would show up and we would customize a computer for their use, and one freshman girl sat down at a computer whose monitor advertised that it was "Low Radiation". Well, her mother was not about to have her little girl sit in front of a monitor that emitted radiation, so she demanded I change her monitor for another that didn't have those words. I offered that all monitors emit radiation, as does the sun, but she was to have none of that and insisted I protect her little girl.

In the end, she got what she wanted - a different monitor that exposed her daughter to even more radiation during the entire year.

My Grandfather, an otherwise very intelligent man, thought that it was unsafe to use a microwave as it would irradiate the food. My Grandmother is still not entirely happy that it is safe to eat food directly from the microwaves as it "Will keep on cooking inside of you." I guess that often new fangled technology just is a little overwhelming. I hope we won't be the same in our golden years, but I fear that it's quite likely.

Your Grandfather's Grandfather probably thought it unsafe to use them newfangled 'lectric burners on the stove, and your Grandfather probably hoped he wouldn't be the same in his golden years, but that it was quite likely.

I'm sure the stuff our grandkids use will scare the tar out of us as well.

Some years back in the office, we had a microwave behind the wall but near our office area. A new worker moved in and raised a fuss about the microwave being too close, going on and on about supposed dangers of microwaves (even at distance), so it was moved to a less convenient location. As we soon found out, he was a heavy smoker, and took frequent breaks so he could go outside to smoke.

If I see something that looks important, I don't see any reason not to just post it if the point made is very clear.
She says that the cancer rate in Baghdad has gone up 700 percent. She says it's because of depleted uranium. If it's not because of depleted uranium, it's because of chemical weapons or something else. All we have to do is veryify whether the cancer rate has indeed gone up 700 percent.

Quote:
Iraq, Yugoslavia, Afghanistan, and now Lebanon are now uninhabitable. Israel soon will be.

Er, uninhabitable?

How do you explain all the people that live there? Long as they're there, those places could definately still be called habitable.
She didn't say that people instantly died when they arrived there. She said that people who live there will probably develope cancer within a few years of arriving there and their offspring would have a good chance of being born deformed. If that's true, that makes it uninhabitable.

In view of what's been happening in Baghdad over the last few years, and the fact that various estimates for the number of violent deaths differ by a factor of ten, how reliable are her statistics? Surely it is easier to count corpses than to count cancer cases?

I have a reason for you. It clearly violates rule #9 of the BAUT forum and is considered a seriuos violation. Should it be reported, it can lead to warnings or bannings. Especially since at least half a dozen people, including myself, have repeatedly warned you about this, I suspect the leniency given would be small.

The technique of posting a single provocative statement (or, commonly, a URL to a pseudoscience website) and then never posting again in a thread is greatly frowned upon. This is only a step above trolling. Barely.

There are some more good documentaries at the bottom of this link. They start where it says, "Invisible War: Part I".

http://www.planetquo.com/Gulf-War-Sy...evel-Radiation

I watched the first one. It like the others I've posted made me wonder about what is happening so I decided to post it so others could see it too. The point it makes is pretty clear. DU shouldn't be used in war because it contaminates the area. I'm just a layman so all I can do is try to verify whether the cancer statistics given are true. If they are, DU is probably as dangerous as alleged in the documentaries.
Who has an opinion on this?

If the truncated link above doesn't work, put these two half links together.

Well David C, rest easy, because the last I knew, DU is no longer used.
The substance of choice is tungsten. Got this from people I've worked with when I was in the navy.

In addition to verifing startistics, you should also verify the credibility of the person making the claims.
It's been shown by others here that the person making the claims about DU is not really a credible individual.
You also ought to consider that with claims regarding the moon hoax.

Oh yes, did you not read the post earlier in this thread about the person that mentioned he handled DU with his bare hands (Tunga's post, #47)?
What have you to say about that?

It's always a good idea to question the validity of any statistics. For example, it's possible that the statistics are wrong. It's also possible they're right but it's due to detection bias. By that, I mean if medical services are open to more people than before, then more people might be diagnosed with cancer than before while the actual rate of occurrence is the same. In that case, it doesn't mean more people are getting sick than before, it just means that more people are getting proper diagnosis. Before, they may have just died on unknown causes.

Depleted uranium is used as an anti-armor munition. It isn't used all that commonly. I don't recall all that many armored actions in Baghdad, so widespread use of DU there seems unlikely.

David, I sympathize with your concern for the people of Baghdad, but let's look at the numbers a bit before we jump to conclusions.

The first Google hit for depleted uranium exposure
is from the World Information Service
on Energy (WISE) Uranium project. I recommend you take a look at the
main Uranium project page.
Keep in mind this is an anti-nuclear organization.

I won't quote all the exposure rates listed on that page, but I've
pulled out what I think are the most relevant numbers for this issue.

Quote:
The gamma dose rate from a 30 mm DU-bullet (271 g) at a
distance of 1 m is 7 nSv/h (hardly to distinguish from background of
typically 100 nSv/h; in the very long term, however, the dose rate
would rise to a maximum of 544 nSv/h after 2 million years; see also:
Uranium Radiation
Individual Dose Calculator
). For the gamma dose rate
from DU dispersed over soil of a target area, the UNEP/UNCHS Balkans
Task Force (BTF) made the following theoretical assessment [BTF1999
p.61]: 10 kg DU dispersed over 1000 m2 result in 4 µSv/a. The effective
dose from inhalation of 1 mg uranium depleted to 0.2% is 0.12 mSv.
I recall from radiation training that the average annual radiation
exposure per person from background radiation and other sources (diet,
etc) is ~ 360 mrem = 3.6 mSv. The US standard exposure beyond
background for non-rad workers is 100 mrem = 1 mSv per year, and for
rad workers it's 1 rem = 10 mSv per year.

The exposure per individual in an area where DU has been used will
vary circumstantially; dust in the air will affect a larger group of
people over a small time, but bullets embedded in a wall will affect a
small group over a longer time (though I don't think much would be
left of the wall after a 30 mm round ). I think it's safe to
say, that a small fraction of people in the war zone would be exposed
directly to more than the allowable amount of radiation in a short
time.

Some helpful numbers would be how much DU (by weight) has been used
in Iraq, how much per km^2 has been used in areas with the greatest DU
use, and what in forms (by percentage) this DU has been deposited (solid,
dust, potential groundwater exposure). Then you could work out a
quantitative estimate of exposure per person in a given area.

All that aside, there's another hole in your argument. Even if the
cancer rate is verified to have increased 700% since the start of the
war, it is fallacious to assume the increase was solely due to DU -
'post hoc ergo propter hoc'. I contend, that as the dominant exposure
is low-level, symptoms such as cancer rate would not appear in the
short term, and birth defects would not be affected at all (by DU, at
least).

What have you to say about that?
I'll weigh in!

From the same source in my previous post:
Quote:
On direct contact with a DU penetrator, the skin dose rate from gamma and beta radiation is 2 mSv/h [AEPI1995 p.107]. With ICRP60's tissue weighting factor for skin of 0.01, this results in a committed effective dose of 20 µSv/h.
So, unless you're committed to continuously handling that DU for a while (we're talking a couple days), you're not going to get close to the allowable dose. You might be in trouble if you had a DU bullet embedded in your tissue though.
