BiPiSci: Rethinking Chernobyl (5-11-2019)

Big Picture Science

Hosts: Seth Shostak and Molly Bentley

The catastrophic explosion at the Chernobyl nuclear power plant in April 1986 triggered the full-scale destruction of the reactor.  But now researchers with access to once-classified Soviet documents are challenging the official version of what happened both before and after the explosion. They say that the accident was worse than we thought and that a number of factors – from paranoia to poor engineering – made the mishap inevitable.  Others claim a much larger death toll from extended exposure to low levels of radiation.  But with nuclear energy being a possibly essential component of dealing with rising carbon dioxide emissions, how do we evaluate risk under the long shadow of Chernobyl?
