      <subfield code="a">The linear, no-threshold model is commonly used for estimating lifetime lung cancer risk from asbestos exposures. Studies of chrysotile workers have observed shallow slopes for the exposure-response relationship for miners/millers, friction products manufacturing workers and asbestos-cement workers but a steeper slope for textile workers. For chrysotile exposures in buildings, where short fibres constitute the great majority of the fibres, the shallow slope is judged more appropriate. Using this slope the data regarding exposure levels to building occupants and maintenance workers, the annualized risks of lung cancer would be approximately 0.01 and 0,6 per million for these groups, respectively. Using the higher slope would result in risks 16 times higher, still considerably lower than those commonly accepted</subfield>
