Origin and health risks of indoor radon.

Radon has always been a component of ground and air and it has been present in increased concentrations from the moment humans first sought shelter inside dwellings. Recent improvements in the energy efficiency of dwellings have led to increased concentrations of radon and to increased risks of lung cancer. To quantify the magnitude of this risk, well-designed epidemiological studies, including surveys of representative dwellings, are needed, and several are being implemented. In the meantime, the EPA and other agencies have offered guidance on monitoring procedures and remedial measures appropriate for the problem on indoor radon. Recent disclosures of relatively high concentrations of radon and radon decay products in homes in several parts of the country have increased public concern about the problem. More information and education are needed about the health risks of radon, the desirability of implementing monitoring procedures for radon, and about remediation measures when detected levels are above average. Educational resources are needed in communities to address local issues when they arise. These resources should include knowledgeable individuals who can work with state and county health officials to put public concerns into perspective within the local context. Physicians, other health professionals, and medical scientists have the knowledge and credentials to be these individuals. To provide health professionals with knowledge and skills to communicate with the public about the health risks of radon, the American Medical Association has prepared an authoritative report and initiated a series of regional seminars on the origin and health risks of radon.(ABSTRACT TRUNCATED AT 250 WORDS)

Radon in homes: determining risks and preventing exposures.

Knowledge about the effects of radon disintegration products and their levels in the nation's homes indicates that in a small proportion of homes these radioactive substances are increasing the inhabitants' risks of lung cancer. Testing for the problem and reducing its magnitude are the homeowner's responsibility. While practical methods for testing are known, they may not be easily available in all regions. Present understanding of the techniques of prevention and remediation is less satisfactory.

Use of animals in biomedical research. Historical role of the American Medical Association and the American physician.

From the introduction of the "Gallinger-DC" bill in 1896 to the passage of the Laboratory Animal Welfare Act in 1966, organized medicine and the American physician have been active in promoting the humane and appropriate use of research animals and explaining to the public and legislators the importance of research using animals to medical progress. The role of organized medicine and science in events leading to passage of federal legislation is discussed. Past efforts of the American Medical Association and the American physician have been critical in numerous successful efforts at the local, state, and national level to prevent the passage of laws which restricted animal use for health research and impeded medical progress. This article demonstrates that current initiatives by physicians to preserve biomedical research are a reaffirmation of their traditional role.

Technology assessment in medicine. The role of the American Medical Association.

Public policy decisions about health care and decisions about an individual patient's care are only as sound as the data and information on which they are founded. The formal systematic evaluation of the safety, effectiveness, and cost-effectiveness of a medical technology provides such information and is essential to the appropriate application of technology in patient care. The American Medical Association (AMA) historically has recognized the need for the practicing medical community to develop and communicate accurate and balanced evaluative information to physicians and other health care professionals. In recent years, the association has established formal programs to accomplish this objective. This article describes the AMA's three major assessment programs, the Diagnostic and Therapeutic Technology Assessment program, the Council on Scientific Affairs, and AMA Drug Evaluations. The implications of these activities for patient care and public policy are discussed.

Detection of low-contrast signals. A comparison of observers with and without radiology training.

Sixteen observers averaging 7.4 years experience in interpreting radiology images and 16 observers without radiology training were tested for their ability to detect low-contrast signals in structured noise backgrounds using a digital display system. No significant difference in true positives, false positives, time to complete test, or a calculated "performance value" could be detected between the two groups. Data from the beginning and end of the test indicated that no difference in performance between groups evolved as the test progressed. Therefore, radiology training seems to offer no significant advantage in low-contrast signal detection in an unfamiliar structured noise background, nor in rapid development of better search strategies or decision criteria.
