Slavutych, Ukraine –
Nikolay Solovyov was on shift the night of April 26, 1986, when the Chernobyl nuclear power plant exploded. Instead of fleeing, he chose to fight his "first war" against radiation.
Four decades later, a second war — Russia's invasion of Ukraine — has taken his son.
Solovyov, 67, a fan of hard rock music, still wears his hair long, though it has turned gray.
