Robert Fisk: Mystery of Israel's secret uranium bomb
Alarm over radioactive legacy left by attack on Lebanon

But scientific evidence gathered from at least two bomb craters in Khiam and At-Tiri, the scene of fierce fighting between Hizbollah guerrillas and Israeli troops last July and August, suggests that uranium-based munitions may now also be included in Israel's weapons inventory - and were used against targets in Lebanon. According to Dr Chris Busby, the British Scientific Secretary of the European Committee on Radiation Risk, two soil samples thrown up by Israeli heavy or guided bombs showed "elevated radiation signatures". Both have been forwarded for further examination to the Harwell laboratory in Oxfordshire for mass spectrometry - used by the Ministry of Defence - which has confirmed the concentration of uranium isotopes in the samples.
Dr Busby's initial report states that there are two possible reasons for the contamination. "The first is that the weapon was some novel small experimental nuclear fission device or other experimental weapon (eg, a thermobaric weapon) based on the high temperature of a uranium oxidation flash ... The second is that the weapon was a bunker-busting conventional uranium penetrator weapon employing enriched uranium rather than depleted uranium." A photograph of the explosion of the first bomb shows large clouds of black smoke that might result from burning uranium.
Enriched uranium is produced from natural uranium ore and is used as fuel for nuclear reactors. A waste productof the enrichment process is depleted uranium, it is an extremely hard metal used in anti-tank missiles for penetrating armour. Depleted uranium is less radioactive than natural uranium, which is less radioactive than enriched uranium.

Chris Bellamy, the professor of military science and doctrine at Cranfield University, who has reviewed the Busby report, said: "At worst it's some sort of experimental weapon with an enriched uranium component the purpose of which we don't yet know. At best - if you can say that - it shows a remarkably cavalier attitude to the use of nuclear waste products."
The soil sample from Khiam - site of a notorious torture prison when Israel occupied southern Lebanon between 1978 and 2000, and a frontline Hizbollah stronghold in the summer war - was a piece of impacted red earth from an explosion; the isotope ratio was 108, indicative of the presence of enriched uranium. "The health effects on local civilian populations following the use of large uranium penetrators and the large amounts of respirable uranium oxide particles in the atmosphere," the Busby report says, "are likely to be significant ... we recommend that the area is examined for further traces of these weapons with a view to clean up."
