Testing the Troops

Military personnel of the Gulf and Kosovo conflicts are to have urine tests for radation exposure by mass spectrometry.

The tests are part of a study of cancer, kidney damage and other potential health problems caused by depleted uranium exposure from armour-piercing shells. The U.K. government will publish results at the end of 2002

Depleted uranium munitions were first fired in the Gulf war of 1991, releasing 339 tons of the toxic metal into the environment. Although one survey said that around 17 per cent of UK soldiers believed they had Gulf war syndrome, it has been difficult to disentangle the health effects of uranium from those of vaccinations, chemical warfare antidotes, insecticides, rodenticides, solvents, lubricants and smoke from burning oil wells.

Scientists believe with mass spectrometry that it should still be possible to tell whether a soldier who fought in the Gulf inhaled as little as 25 milligrams of uranium. This level is linked with a small increased risk of lung cancer but no toxic effects on organs.

Professor Brian Spratt, chairman of a Royal Society working group, called for soldiers in future wars to be tested for the heavy metal. Their kidney function should also be assessed and they should be warned of the long-term risks to children who live where munitions were once used.
