Ryuichi Hirokawa, a Japanese photojournalist, has documented the world's two worst nuclear crises — in Chernobyl three decades ago, and the 2011 meltdown at the Fukushima No. 1 power plant.
With this year marking the 30th anniversary of the Chernobyl disaster, Hirokawa, 72, has released a photo book titled "Chernobyl and Fukushima" compiling his reports on the lives of victims of the catastrophes.
After years of reporting on the two disasters, Hirokawa said he has concluded that nuclear power "is not something human beings can handle or control."
