An international survey made in 1958, with the Comite"s Nationaux de Lutte Antituberculeuse, provided a large body of information gathered from Austria, Belgium, Canada, Denmark, France, Great Britain, Japan, Netherlands, Rumania, Switzerland, and Spain, relating to radiation dosages in detection of tuberculosis. It was found that in these countries with the equipment and techniques in use at the time, radiography necessitated a radiation dose of 200- 640 mr as measured on the dorsal surface of the thorax, whereas fluoroscopic examination required doses ranging from 700 mr to 15 r, according to technique employed. Gonadal doses were negligible with radiography, and the significant genetic dose for the entire population was estimated to be not over 80 mu r in one country where approximately 55 million photofluorographic examinations were made in 1958 in persons under 30 years old. The average bone marrow dose per inhabitant varied from 0.2 to 37 mr in the various countries. Plumonary fluoroscopy exposes the individual to greater somatic and gonadic radiation and, it is suggested, should be eliminated from antituberculosis programs. To reduce patient exposure during thoracic radiology, the following precautions are recommended by the Commission de la Radiologie de l'Union Internationale contre la Tuberculose: use of mirror camera: adoption of higher film sensitivity and iniproved development techniques; use of higher maximum kilovoltage; establishment of a screen focus distance at less than 1 m; filtration with 3 mm of aluminum; exposure time of less than 1/10 sec; use of beam-localizing diaphragm and, if necessary, of a lead apron. Chest roentgenography still remains the most effective means for detecting new cases and follow-up examination in tuberculosis, and with adequate safeguards to minimize patient radiation, exposure does not present undue hazards.
