!
Not all radiation is the same, so scientists use the ‘sievert’
to measure the health risks of radiation.
A one-sievert dose of radiation (SV) would cause
immediate radiation sickness. But most radiation doses are
much smaller, so you’ll see them measured in millisieverts
or even smaller microsieverts.
1 sievert (Sv) = 1000 milli-sieverts (mSv/h)
1 milli-sievert (mSv/h) = 1000 micro-sieverts (μSv/h)
RADEX geiger counters use micro-sieverts (μSv/h)

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.

ALERT - No need to panic, but try to figure 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.

Annual limit for Nuclear Plant Workers.
100,000 Annual limit for Fukushima workers.
