The diagnostic value of radiophotograms (R. P.) and the reading ability of readers play an important role in the efficiency of mass case-finding by X-ray.<BR>The study was carried out to investigate the diagn o stic value of 70 mm R. P. by mirror camera and to evaluate the reading ability of physicians working in the T. B. control, based on the results of a R. P. reading contest.<BR>A total of 192 physicians had participated in the contest. Most of them were from health centers, health service sections of enterprises, mass examination specialized agencies, etc.<BR>Fifty R. P. pictures were read by each reader at the contest. They were consisted of 25pictures showing active lesions of pulmonary tuberculosis or other chest diseases, , 5 with healed lesions only, and 20 without lesions. Those cases had been diagnosed precisely by radiograms and other examinations.<BR>If a reader failed to indicate a further examination for a case with active lesions, it was judged "overlooking", and if he indicated a further examination for a case without lesions, it was judged "overreading"
