Biological Effects of Radiation MIT 22.01 Introduction to Nuclear Engineering and Ionizing Radiation, Fall 2016 Instructor: Michael Short View the complete course: https://ocw.mit.edu/22-01F16 YouTube Playlist: • MIT 22.01 Introduction to Nuclear Eng… The longer-term effects of accumulated radiation exposure are shown from the cell to the organism level. Trends in cell division rate are linked to both the various symptoms of radiation poisoning and the relative biological susceptibility of different organs. Sources of our knowledge of the effects on large and small doses of radiation are shown, paying particular attention to our lack of definitive knowledge of the effects of very low doses of radiation.
