`^228Th`emits an alpha particle to reduce to `^224Ra`.Calculate the kinetic energy of the alpha particle emitted in the following decay:`^228Th rarr ``224Ra**+ alpha`  ``224Ra** rarr `224Ra+ gamma(217 keV). Atomic mass of ``228Th` is 228.028726 u,that of ``224Ra`is 224.020196 u and that of ``_2^4He` is 4.00260 u.
