Relation between radiographic categories of coalworkers' pneumoconiosis and expectation of life.
A 20-year follow-up of the male population of the Rhondda Fach, examined in 1950-1, has been completed. Survival rates for miners and ex-miners appear independent of the x-ray category of pneumoconiosis except for category B or C, where survival rates are much reduced.
