XKCDs Radiation Dose Chart

This is a chart of the ionizing radiation dose a person can absorb from various sources.  The unit for absorbed dose is “sievert” (Sv), and measures the effect a dose of radiation will have on the cells of the body.  One sievert (all at once) will make you sick, and too many more will kill you, but we safely absorb small amounts of natural radiation daily. Note: The same number of sieverts absorbed in a shorter time will generally cause more damage, but your cumulative long-term dose plays a big role in things like cancer risk.


This is really fascinating, and totally plays into some of our previous coverage.

What’s a sievert? He was Rolf Sievert, a Swedish radiation physicist obsessed with dose. And now it’s the sievert, or Sv, established in 1979 as an international unit for radiation dosing:
1 Sv = 1 J/kg
