Elena L [17]

Decay of Uranium-238 produces gamma radiaton whereas decay of thorium-234 releases beta radiation.

<h3>What type of radiation is produced?</h3>

In the decay of U-238, two gamma rays of different energies are emitted in addition to the alpha particle while on the other hand, in the decay of thorium-234 , beta rays are emitted.

So we can conclude that decay of Uranium-238 produces gamma radiaton whereas decay of thorium-234 releases beta radiation.
