Aidana is four years old. She was born with two heads, and not for a wicked hoax of destiny, but because she was born in the most radioactive spot of the planet: Semipalatinsk, in Kazakhstan. For fifty years, until 1991, this area was the main atomic site of the Soviet Union and one of the gloomiest chapters in the whole history of the Cold War. All nuclear and thermonuclear bombs launched in this little Asian region were by 2.800 times more powerful than those of Hiroshima. Epidemiological data are nevertheless undeniable: 70.000 people died and more than 300.000 are sick as a consequence of radiations.
