18 Aspart of the cancer surveys, roentgenogramsof the chest on all of the population understudyare scheduled every 2 to 3 years. Chest plates on some 100 people were made during the past 2 years. Only 2 cases thought to be tuberculous were noted, and these appeared to be old fibrotic inactive disease in older people. Otherwise evidence for pulmonary and cardiac diseases was minimal.
