Radioactive Contamination Effects?

http://www.indybay.org/news/2006/03/1810728.php Uranium bombing in Iraq contaminates Europe by Bob Nichols, Project Censored Award Winner Nine days after the start of the American president's 2003 "shock and awe" uranium bombing campaign in Baghdad, an invisible radioactive uranium oxide gas cloud swept through Britain's towns and countryside and throughout Europe. Respected scientists reported on the unrevealed gas cloud after conducting research on specialized high volume air filters in England. Dr. Chris Busby and Saoirse Morgan stunned Europe in a Sunday Times of London article on Feb. 19, 2006. Their scientific paper, released March 1st, 2006, [1] proved the event. With all the vigor of delusional drunkards, British nuclear and military spokesmen predictably denied the reality of an invisible radioactive cloud. snip At Aldermaston, England, where the data was collected and where the British Atomic Weapons Establishment, complete with air monitoring facilities, is located, the deadly uranium oxide gas measured about 48,000 radioactive particles per square meter. The average radioactive dose, according to official government index based calculations, was about 23 million radioactive particles for the average adult male in Britain and Europe. The rest of the article is at the above link. My question is: What is the likely effect of the above radiation dose to Joe Public? Is it significantly above background levels?
