Uranium-238 decays into thorium-234 plus an alpha particle. The known masses are
$$\begin{array} { l l }
{ } _ { 2 } ^ { 4 } \mathrm { He } : & 4.002603 \mathrm { u } \
{ } _ { 90 } ^ { 224 } \mathrm { Th } : & 234.043583 \mathrm { u } \
{ } _ { 92 } ^ { 238 } \mathrm { U } : & 238.050786 \mathrm { u }
\end{array}$$
How much energy is released in this process? $\left( 1 \mathrm { u } = 931.5 \mathrm { MeV } / c ^ { 2 } \right)$
