Low radiation dose: The effects of low dose radiations on human health have been a major considerable attention because of the increasing medical use of ionizing radiation, during diagnostic and therapeutic medical procedures, as well as environmental events, such as atomic power plant accidents. Since the fifties, the prime concern of radiation protection has been protecting DNA from damage. Furthermore, human exposure to ionizing radiation (IR) disrupts normal metabolic processes in cells and organs by inducing complex biological responses that interfere with gene and protein expression.
Is Low dose radiation exposure inducing cancer? : Low doses of radiation affected biochemical and functional cell and tissue responses in various mammalian cells that express both damage and adaptive cell protection, the protective responses differ according to species, cell type, cell metabolism, and cell cycle. The probability of low-dose induced cancer arises from a balance between low-dose induced oncogene and various types of adaptive protection against oncogene and tumor development. Cellular Defense, DNA Damage and Repair that is give an indicator for the effect of radiation exposure through biomarkers, apoptosis and cell cycle checkpoints.
Cancer risk for non cancer patients going imaging test: radiation imaging test is using for different diseases other than cancer, which help the patients in therapy response, so that, evaluation the health risk of low dose radiation exposure is very attenuation among the benefits and the risk of cancer from radiation exposure. This is an important field in radiobiology and Biodosemitry branches to achievement the effect of radiation exposure for population. Further studies in cell culture and experimental animals are needed to assess the biological effects of low dose radiation through biomarkers and achieved which low dose range may affected DNA alteration.
