It was 28th April 1986, early morning in Poland. The radiation monitoring station in Mikołajki, Mazury area (north-eastern region of Poland - which is much further north) showed that the radioactivity in the air was 550,000 times higher than the day before. The radioactive cloud from Chernobyl had travelled to Poland.
We all had to take iodine pills for long time. I guess if you never lived close to nuclear accident place you just can't understand it.
And if 550,000 times standard radiation doesn't speak to you then go and take deep breath in Chernobyl, and stay there for a bit. Wish you good luck and quick death cause cancer from damaged cells will come 100%.
