Answer

Brief Explanations:

In alpha - decay, a nucleus emits an alpha particle which is a helium - 4 nucleus ($^4_2He$). In the given equation, uranium - 238 ($^{238}{92}U$) decays into thorium - 234 ($^{234}{90}Th$) and a helium - 4 nucleus ($^4_2He$), which is characteristic of alpha decay.

Answer:

alpha decay
