Answer:
Step-by-step explanation:
A proton is a subatomic particle, and it is not a unit of radiation energy. The proton is the positively charged particle found in the nucleus of an atom. It is made up of three quarks, two up quarks and one down quark.
The unit of radiation energy is the electronvolt (eV). The eV is the energy gained by an electron when it falls through a potential difference of 1 volt.
Protons can be used to produce radiation energy, but they are not themselves a unit of radiation energy.
For example, a proton beam can be used to produce X-rays, which are a type of electromagnetic radiation. The energy of the X-rays produced will depend on the energy of the proton beam.
Another example is proton therapy, which is a type of cancer treatment that uses proton beams to damage cancer cells. The energy of the proton beam is chosen so that the protons stop at the tumor site, and deliver their energy to the cancer cells.
So, while protons can be used to produce radiation energy, they are not themselves a unit of radiation energy.
