Not all radiation is the same, so scientists use the ‘sievert’ to
measure the health risks of radiation. 7
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 millisieverts or even smaller
microsieverts.
