Well SupportedInducing DNA breaks without causing mutations or cancer leads to aging phenotypes in mice.

Well SupportedRadiation exposure can lead to chromosome breaks, particularly when damage occurs to both DNA strands in close proximity.

Not SupportedExposure of infants to radiation should only occur for a compelling reason.

Partially SupportedRoutine diagnostic use of CT pulmonary angiography or ventilation–perfusion scanning exposes both mother and fetus to radiation.
