At exposure levels seen in occupational cohorts it is concluded that the exposure specific risk of mesothelioma from the three principal commercial asbestos types is broadly in the ratio 1:100:500 for chrysotile, amosite and crocidolite respectively. For lung cancer the conclusions are less clear cut. ... The risk differential between chrysotile and the two amphibole fibres for lung cancer is thus between 1:10 and 1:50.
