The energy released is the difference in mass between Rn-220 and Po-216+a.
An alpha particle has a mass of 4.00151 u.
The difference is 220.01757u-(21.00179u+4.00151u)=195.0142…
One atomic mass unit is equal to 931.49406 MeV/c^2
The mass difference in MeV/c^2 is then 195.01427*931.49406=181.65463 GeV/c^2
The energy release is equal to the mass difference, so the energy released is 181.65463 GeV
