Radiation Exposure and Estimate of Late Effects of Chest Roentgen Examination in Children

摘要: The energy imparted and the radiation dose to lungs, breasts, thyroid bone marrow at chest radiography of infants children were measured or calculated risk inducing future malignant diseases was estimated. doses various organs corresponded 5 30 per cent yearly background radiation. In both sexes as well for boys a later age, radiation-induced leukemia carcinoma constituted greatest malignancies. After infancy, girls more exposed breast carcinoma. On whole, developing constitutes greater problem than does, example, leukemia. Reversing beam direction from postero-anterior anteroposterior increases this while will remain unchanged.
