I was watching this show called dark tourist on Netflix and in their Japan episode they visited the Fukushima area and received readings of up to 8.4 mcSv/h. My question is firstly what do the units even mean, and secondly how dangerous are these levels of radiation?
In: 11
The unit is Sv, sieverts, which is exposition to radiation measured in J/Kg so Sv/h is the exposure over time… mcSv/h means microsievert, the safe limit for working is considered 50mSv per year, so that’s 50.000mcSv so at 8mcSv/h it’s even considered safe for working
