Low Doses Ionizing Radiations: A Risk for Cancer and Cardiovascular Diseases

Low doses of ionizing radiation (IR) deriving from various sources are a major cause for human's health problem for those who are continuously exposing to it. Recently, radiation has become associated with a much broader spectrum of age-related diseases, including cancer and cardiovascular disease (CVD). Recent studies have examined the risk of cancer and CVD in humans exposed to various sources of IR. These studies indicated the linear dose-response relationship of low doses IR and oxidative stress, resulted in increased risk for cancer and CVD. Previous studies indicated that there is a strong association between prolonged exposure to low doses IR with cancer and CVD.
