The
misnamed 'Depleted' Uranium is left after enriched uranium is
separated from natural uranium in order to produce fuel for
nuclear reactors. During this process, the fissionable isotope
Uranium 235 is separated from uranium. The remaining uranium,
which is 99.8% uranium 238 is misleadingly called 'depleted
uranium'. While the term 'depleted' implies it isn't particularly
dangerous, in fact, this waste product of the nuclear industry
is 'conveniently' disposed of by producing deadly weapons.
Depleted uranium
is chemically toxic. It is an extremely dense, hard metal,
and can cause chemical poisoning to the body in the same way
as can lead or any other heavy metal. However, depleted uranium
is also radiologically hazardous, as it spontaneously burns
on impact, creating tiny aerosolised glass particles which are
small enough to be inhaled. These uranium oxide particles
emit all types of radiation, alpha, beta and gamma, and can
be carried in the air over long distances. Depleted uranium
has a half life of 4.5 billion years, and the presence of depleted
uranium ceramic aerosols can pose a long term threat to human
health and the environment.
In the 1950's the
United States Department of Defense became interested in using
depleted uranium metal in weapons because of its extremely dense,
pyrophoric qualities and because it was cheap and available
in huge quantities. It is now given practically free of
charge to the military and arms manufacturers and is used both
as tank armour, and in armour-piercing shells known as depleted
uranium penetrators. Over 15 countries are known to have
depleted uranium weapons in their militaray arsenals - UK, US,
France, Russia, Greece, Turkey, Israel, Saudi Arabia, Bahrain,
Egypt, Kuwait, Pakistan, Thailand, Iraq and Taiwan - with depleted
uranium rapidly spreading to other countries. Depleted
uranium was first used on a large scale in military combat during
the 1991 Gulf War, and has since been used in Bosnia in 1995,
and again in the Balkans war of 1999.
A sub-commission
of the United Nations Commission on Human Rights appointed a
'rapporteur' to investigate the use of depleted uranium weapons
among other types of weapons, after passing a resolution which
categorised depleted uranium weapons alongside such as nuclear,
chemical and biological weapons, napalm, and cluster bombs as
a 'weapon of indiscriminate effect'.
Depleted uranium
is also used in civilian products. For example, it is
used as ballast in aeroplanes (having disastrous consequences
in 1992 when an El-Al jet crashed into flats near Amsterdam
- depleted uranium was also involved in the recent Stansted
Korean Air crash - see CADU News issue 3 for full report).
It is also used in some hospital equipment. The alarming
Euratom (European Atomic Energy Community) objective which will
allow the 'recycling' of low-level radioactive waste in to consumer
goods has also raised concerns that depleted uranium may be
used in this way.
Making
weapons and other items out of the waste products of the nuclear
business is a very 'convenient', very cheap, but potentially
deathly way to get rid of the nuclear waste stockpiles
