<abstract displayLabel="Summary">The cumulative fibre exposure of 36 deseased persons who had been employed on crocidolite asbestos mines of the NW Cape Province, Republic of South Africa was compared with their lung burden determined by fibre count by optical microscope. Allowance for the period which lapsed between date of last exposure and death revealed a lung clearance rate amounting to a half-life of about 6 years</abstract>
