WebIntroduction. Ionizing radiation (IR) is an environmental carcinogen [Citation 1], with natural (radon, cosmic, soil and food) and human-made (medical, nuclear industry and power plant accidents) exposure sources.Exposure to IR occurs through different radiation regimes (low or high doses and dose rates; acutely, chronically, or protracted). WebKey points: All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles.
