Uranium is used in Iraq, Gaza Strip, and Lebanon

Health problems from the radiation is primary reason why people should escape war-zone in the recent wars. Some journalists and photographers would make some fortune from their works in the war zone. Solders have no choice but to battle in war zone where they are assigned. In a long term, visiting war zone or living in war zone would cause health problem for sure. Who suffers from the radiation is not only themselves but also their children and the people who will live in the area.

There is an organization protesting to demand the data of nuke use in Iraq.

The protest, organized by the UK Uranium Weapons Network (UUWN) outside the US Embassy in London, said that the US military had used at least 400 tons of munitions containing depleted uranium in Iraq during the 1991 and 2003 wars.

More over, the article says that it might be done in Gaza Strip and Lebanon.

The number of cancer patients and birth defects linked with depleted uranium weapons are on the rise across Iraqi cities and towns, according to media reports.

Medics have also found traces of depleted uranium munitions used by the Israeli army during its invasion of the Gaza Strip and Lebanon.

Israel has also defied UN demands to map out the areas in Lebanon where its army had used cluster bombs.

I think there must be some regulation for the uranium use in the war. If it is about bombs left after the war, the country responsible for it will help to take out the remained ones. Land mines are also the same. Radiation cannot be wiped out easily, however the country responsible for the cause or the WHO may do something else such as materials that reduces the effect from the radiation.
