Radiation Level Implications

25 Mar

Lately, Japanese authorities are all with eyes wide open about the ongoing activity in the nuclear reactor in Fukushima and the fear of harmful radiation leaks from a number of reactors. Ionising radiation can be harmful to human life at different levels. The following is a classification of the implications of radiation levels on human life as published by the US Environmental Protection Agency.

  • 50-100mSv: Changes in blood chemistry
  • 500mSv: Nausea, within hours
  • 700mSv: Vomiting
  • 750mSv: Hair loss, within 2-3 weeks
  • 900mSv: Diarrhoea
  • 1,000mSv: Haemorrhage
  • 4,000mSv: Possible death, within two months, without treatment
  • 10,000mSv: Destruction of intestinal lining, internal bleeding and death within two weeks

(mSv = millisieverts)
