The product of the nuclear reaction in which 31p is subjected to neutron capture followed by alpha emission is

Explanation:

A nuclear reaction is defined as a reaction in which two nuclei combine together to result in the formation of a new nuclei.

When two nuclei combine together then it is known as nuclear fusion. And, when a large nuclei split into two small nuclei then it is known as a nuclear fission reaction.

For example,

As we know that alpha particle is .

So, when is subjected to neutron capture followed by alpha emission then products are along with emission of a positron.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

first one is the correct answer
