Helium radiation
Web13 nov. 2013 · We’re bombarded with the radiation of supernovae and other cosmic sources when we fly – how concerned should we be? WebUnlike Earth, which is protected by its magnetic field, the Moon has been bombarded with large quantities of Helium-3 by the solar wind. It is thought that this isotope could provide safer nuclear energy in a fusion reactor, since it is not radioactive and would not produce dangerous waste products.
