MET - 01 - Biological Effects of Ionising Radiation

This video provides an overview of how ionising radiation interacts with human biology, drawing on historical data from medical workers and atomic bomb survivors to establish safety standards. The author distinguishes between deterministic effects, which cause immediate tissue damage and cell death once a specific dose threshold is crossed, and stochastic effects, which involve random genetic mutations that may result in cancer or hereditary issues years later. Central to the discussion are the mechanisms of DNA damage, highlighting how cells either repair themselves or undergo programmed death, as well as the unique radio-sensitivity of embryos and foetuses during different stages of development. Ultimately, the work serves to define the scientific basis for radiation protection, utilising specialised metrics like absorbed, equivalent, and effective doses to manage risks for both professionals and the general public.
