Radioactive Material Stolen In Iraq

Iraq is searching for 'highly dangerous' radioactive material stolen last year, according to an environment ministry document and seven security, environmental and provincial officials who fear it could be used as a weapon if acquired by Islamic State.

 The material, stored in a protective case the size of a laptop computer, went missing in November from a storage facility near the southern city of Basra belonging to U.S. oilfield services company Weatherford WFT.N, the document seen by Reuters showed and officials confirmed.

 A spokesman for Iraq's environment ministry said he could not discuss the issue, citing national security concerns.

My question is what is an oilfield service company doing with the stuff in the first place!?
