[ RadSafe ] Astrophysicists Report Radioactive Cobalt in Supernova Explosion

[Brennan, Mike (DOH)]

As I understand it, if you are close enough to a supernova that the gamma is significant, you have other fairly pressing concerns.

Supernovae produce about a solar mass (10^30 kg) of Co-56, which decays to Ni-56, and thence to Fe-56. The total amount of gamma energy released by the decay of the Co-56 and Ni-56 to stability is more than 10^49 ergs. I wrote a paper on this topic - along with the attenuation of the gamma dose by the supernova remnant and radiation dose to nearby stars and planets - in 2002; I believe it appeared in Radiation Physics and Chemistry.

Cool stuff!
