Hello, I live not really far from Sankt Peterburg(Russia) and yesterday there was accident, where radioactive gas leaked from reactor. They told those gases headed straight to Finland and Estonia, but in these such of accidents truth is never told for people. Like... lets remember Japan. Consequences may had been avoided if truth were told for people. How can I protect myself from it ? I was googling about measuring it but only found EMF, I guess it's not what I need? What kind of measuring unit do I need and what kind of device can I buy to measure it?
