10 grams of a highly radioactive isotope of Iridium were stolen in Iraq: http://www.independent.co.uk/news/w...clear-dirty-bomb-iraq-oil-field-a6879481.html We don't need more radioactive pollution, do we? Why is such a substance and in this amount, not better guarded? I have a source that says the substance was used to detect problems in oil pipelines. http://www.heise.de/tp/artikel/47/47446/1.html Translation attempt, "With the substance, leased from SGS Turkey by the US company Weatherford, oil pipelines were scanned for material defects. Both companies remain silent about the accusations."
