De Sadesky says that the fallout from the doomsday device has a half-life of 93 years, but then he also says that the fallout would circle Earth for 93 years. This is a contradiction: half-life is the time it takes for radiation to be halved, not completely dissipated. It is common however for people to confuse these concepts, and the dissipation time for the fallout from a nuclear weapon salted with cobalt is indeed about a century.
