John Hodgson and Andrew Darnton published an important paper investigating the risk of mesothelioma (and lung cancer) in 2000 . The concluded that for historical exposure levels the risk of mesothelioma from the three main commercial asbestos types was roughly in the ratio 1:100:500 for chrysotile, amosite and crocidolite respectively. So from this analysis for the same fibre exposure crocidolite is 500 times more likely to cause mesothelioma than chrysotile.
