Gordian Knot News • 139 implied HN points • 04 Feb 25
🔬 Science Radiation Health Biology Environment Nuclear
  1. The historical dose limit for radiation exposure was set at 2 mSv per day, based on a time when no harmful effects were clearly detected. This suggests that at this level of exposure, there might not be significant health risks.
  2. Our body has a strong system for repairing DNA damage caused by radiation and natural processes. Most DNA issues are fixed quickly, which means low-level radiation may not lead to serious health problems.
  3. If we accept that 2 mSv per day is safe, it could change how we manage nuclear power. It may allow for safer operations and reduce unnecessary evacuations, ultimately making energy cheaper and more sustainable.
