title: The physician's role in radiation protection.
abstract: Examinations which should not be regularly performed include: chest and lower back x-ray examinations in routine physical examinations; tuberculosis screening by chest radiography; chest x-rays for hospital admission of patients under age 40 (unless there is a clinical indication of chest disease); chest radiography in routine prenatal care, and mammographic examinations for women under age 50 who do not have symptoms or a positive history. X-ray examinations of possibly pregnant patients require appropriate measures to protect the fetus.
