If your wanting to learn more about the Chernobyl Nuclear accident and it’s effect on those who lived and worked around the area then the Chernobyl Museum in Kiev is well worth a visit. Though you may want to considering arranging for a translator or local guide as the majority of the exhibits are in Russian. They do have Audio guides in English however these are not always available. And like most of Museums in Russia and the Ukraine you’ll to get an special ticket if you want to take photographs, just ask when buying your entry ticket.
I’d read from reviews on-line that the museum itself wasn’t that easy to find and about the problems with language barrier so had arranged to a local tour company to provide a tour guide and translator who meet us at our hotel to take us to the museum and also arrange for an English speaking guide.
We spent around an hour and a half at the museum where you can learn about the Chernobyl accident, see global press cuttings from the time, understand the evacuations of Pripyat, and see some of the belongings that people left behind, understand the role of the liquidators who working in 40 second shifts battled to clean up the contamination, and learn of the ongoing work in zone to build the new sarcophagus over the reactor building.
