with regards to Radiation levels, as of today, i dont think there is much to worry about at the moment.
everyones saying its "10 times normal". Well, yes it might be but quantify normal and dangerous. No one one the news knows, theyre just scare mongering.
We are taking of levels of radiation being at around 0.9 sieverts per hour (highest recorded so far away from power plant)
To put that into perspective, you would receive about 50 microsieverts when having a chest xray. I would take a years worth of exposure to 100 microsieverts to cause cancer, 6000 microsieverts would probably kill you in a matter of weeks.
At the Nuclear power station...the levels are about 40 microsieverts.
Whilst im not saying the situation (at the moment) isnt a bad one, of course it is, its not as drastic as the world wants you to thing
