Adverse Health Effects of Sustained Low-Level Radiation Exposure

Collection of data on the risk of adverse health effects caused by exposure to ionizing radiation is in an early stage, with most of the data coming from the studied effect on interventional cardiology teams. Mounting evidence shows a link to a series of significant stochastic health effects, including left-sided brain tumors, posterior subcapsular lens changes (a precursor to cataracts), skin cancers, thyroid disease, and neuro-degenerative disease. More generalized adverse health effects, such as cardiovascular disease and diminishment of reproductive capacity, also may be linked to general chronic, low-dose radiation exposure.1 Significant recent findings in these areas include:
