Solution

The correct option is A
True

Hey, remember conservation of momentum? Also, if we compare the masses of the alpha particle and the daughter nuclei, which is lighter?
Yes, the alpha particle is much much lighter. So, the kinetic energy mostly goes to the alpha particles.

$^{228} Th$ emits an alpha particle to reduce to $^{224} Ra$ . Calculate the kinetic energy of the alpha particle emitted in the following decay:

$^{228} Th \to^{224} {Ra}^{*} + α$

$^{224} {Ra}^{*} \to^{224} Ra + γ (217 keV)$
