Depleted Uranium Weapons – a BBC investigation by Angus Stickler
A BBC investigation can reveal that the US and UK military have
continued to use depleted uranium weapons despite warnings from
scientists that it poses a potential long-term cancer risk to
civilians. A former senior scientist with the United Nations has told
the BBC that studies showing that it was carcinogenic were suppressed
from a seminal World Health Organisation report. The US has refused
to fund major research and has been criticised for failing to
cooperate with UN attempts to conduct a post conflict assessment in
Iraq.
Angus Stickler reports:
When depleted uranium bullets are fired, the rounds can rip through
the tank armour. And once inside - on contact with air they combust
exploding into a 10,000 degrees centigrade ball of fire.
Both the US and UK used depleted uranium in Iraq. The US fired 320
tons in Gulf War I – and possibly as much as 2,000 tonnes in Gulf War
II. But its use is highly controversial - blamed as one of the
possible causes of cancer and birth defects. It's this that prompted
the Untied Nations' World Health Organisation to conduct a major
assessment of the post conflict hazards. The findings were published
in 2001. Dr Mike Repacholi retired as the Coordinator of the W.H.O.
Radiation and Environmental Health Unit in June of this year. He
oversaw the project.
He says, "Depleted uranium is basically safe - you can touch depleted
uranium for hours and not cause and radiation damage you can ingest
it and it's excreted through the body - 99 per cent of it goes within
about a day - you would have to ingest a huge amount of depleted
uranium dust to cause any adverse health effect."
The W.H.O. assessment warns that children should be restricted from
going into post conflict areas. The monograph - as it is called – is
now used by some as the definitive document on the potential health
hazards of depleted uranium. But now this BBC investigation has been
told - its findings may skewed.
Dr Keith Baverstock – now retired - was a senior radiation advisor
with 12 years experience at the W.H.O - part of Dr Repacholi's
editorial team at the time. He came across research indicating that
depleted uranium is a potentially dangerous carcinogen:
"When you breathe in the dust the deeper it goes into the lung the
more difficult it is to clear. The particles that dissolve pose a
risk - part radioactive - and part from the chemical toxicity in the
lung - and then later as that material diffuses into the rest of the
body, and into the blood stream a potential risk at sites like the
bone marrow for leukaemia, the lymphatic system and the kidney"
according to Dr Baverstock.
Health warnings suppressed
This is called genotoxicicty says Dr Baverstock, it could take
decades before evidence of cancer starts to emerge. As part of the
W.H.O. team he submitted these findings - based on peer reviewed
research conducted by the United States Department of Defense - for
inclusion into the monograph. It received short shrift. Dr Repacholi
says this was with good reason.
It was the committee's general conclusion that this data did not
substantiate that there was a health effect at this stage. Was the
science that was in that report - which was research that came
effectively from the US Department of Defense - was it wrong?
DR REPACHOLI: We want a comprehensive report - we want to include
everything that we can - but we don't want fairytale stuff - it
wasn't collaborated by other reports - that was felt to the level
that science would say this was established.
ANGUS STICKLER: My understanding is that at the time that there were
eight published peer reviewed research studies - attesting to the
genotoxic nature of uranium - all of which could have been included
in the monograph?
REPACHOLI: Yep - these - er - papers were speculative at the time and
W.H.O. will only publish data that they know is established.
STICKLER: Shouldn't the World Health Organisation err on the side of
caution?
REPACHOLI: W.H.O is a conservative organisation there's no doubt -
it's not a leader in this sort of thing - it's not out there saying
wow we should be concerned about this, this and this - it's not there
to do that.
Dr Baverstock disagrees. He says the W.H.O stance that this is
inconclusive science is not safe science. He attempted to take the
issue further.
DR BAVERSTOCK: When it wasn't included in the monograph - I with two
other colleagues prepared a paper for the open literature and the
W.H.O did not permit me to submit that paper for publication.
ANGUS STICKLER: Why not - what reasons were you given?
BAVERSTOCK: Well ha - I still have not had a reason as to why that
paper was not allowed to be published.
STICKLER: Could it be the case that the science you're talking about
is unsafe - in that you're - as a scientist - a bit miffed that they
didn't include what you wanted them to include?
BAVERSTOCK: No I'm not miffed about it at all - we use this kind of
laboratory testing in many systems to screen chemicals and to know
whether things are going to be dangerous or not.
STICKLER: Why do you think your study was - as you say - suppressed?
BAVERSTOCK: It is naive to think that in institutions like the United
Nations one is free from political influences - the member states
have their own agendas.
STICKLER: What you seem to be saying there is that the W.H.O. was
pressurised by the likes of the United States to come to the right
conclusion?
BAVERSTOCK: I think that could be the case - yes.
It's ironic that the major player that Dr Baverstock believes was
behind the decision block publication of his study – was the nation
state that conducted the research he was citing: The United States'
Department of Defence Armed Forces Radiobiological Research
Institute: a credible State laboratory. A point I put to Dr Repacholi.
DR REPACHOLI: The problem that W.H.O had and it went right up to the
Director General's office that it was finally disapproved at that
level was that on the basis of the evidence that we have - we can't
conclude that it is harmful - and to have a paper from another W.H.O
staff member that says we absolutely think it's harmful - makes W.H.O
look a bit odd.
STICKLER: With the greatest respect - that's going to have very
little truck with someone who may get seriously ill because of
depleted uranium the fact that the W.H.O. may look a bit odd?
REPACHOLI: No the odd part is that it looks like W.H.O. is not in
control of its shop.
There is undoubtedly a massive gulf between the views of these two
scientists. Dr Repacholi - however - denies that pressure was brought
to bear on the W.H.O.
The findings of the US Department of Defense research - are now in
the public domain: depleted uranium is genotoxic - it chemically
alters DNA and could be a precursor to tumour growth. Since 2001,
there have been numerous studies supporting the findings.
We asked for an interview with the scientist who conducted these
studies - Dr Alexandra Miller – the US Department of Defense refused.
The BBC has been told that she applied to the US Army Research
Programme to do further work on the effects of depleted uranium in
2004, five and six. All the applications were turned down.
