Radiation: How much is harmful?
Not all radiation is the same, so scientists use the ‘sievert’ to measure the health
risks of radiation.
A one-sievert dose of radiation would cause immediate radiation sickness. But
most radiation doses are much smaller, so you’ll see them measured in mil-
lisieverts or even smaller microsieverts.
1 sievert (Sv) = 1000 millisieverts (mSv)
1 millisievert (mSv) = 1000 microsieverts (uSv)
uSv/h micro Sieverts per hour.
0.10 This is low, it does not get any lower.
0.21 Pretty normal. Depends on local geology.
0.42 Happens occasionally with no real reason.
Just keep an eye on it.
0.83 ALERT - No need to panic, but try to gure
out what is going on, stay out of the rain
and avoid unnecessary trips.
1.25 Real risk of cancer if exposed for a year.
4.17 Real risk of cancer if exposed for 90 days.
20,000 Annual limit for Nuclear Plant Workers.
100,000 Annual limit for Fukushima workers.
Sievert calculations based on Cesium-137 isotope.
