Fedor Alexandrovich is a radioactive man. He was four years old in 1986, when he was exposed to the toxic effects of the Chernobyl nuclear meltdown and forced to leave his home. Now 33, he is an artist in Ukraine, with radioactive strontium in his bones and a singular obsession with Chernobyl, and with the giant, mysterious steel pyramid now rotting away 2 miles from the disaster site: a hulking Cold War weapon known as the Duga and nicknamed the Russian Woodpecker for the constant clicking radio frequencies that it emits. Alexandrovich returns to the ghost towns in the radioactive Exclusion Zone to try to find answers – and to decide whether to risk his life by revealing them, amid growing clouds of Ukraines emerging revolution and war.
