    D = Dose rate in (micro Sv/h) - this is what we want M = Activity in MBq (1000 MBq ,since we want 1GBq to match the search results we obtained earlier) E = Gamma energy in MeV (0.662 MeV, obtained from any data book) r = distance from the source in m (0.3 m to match the search results we obtained above). We see tha… See more
