Answer:
Gamma rays are used in an industrial setting to detect defects in metal castings and to find weak spots in welded structures. In a process known as industrial radiography, sections of structures are bombarded with gamma rays which safely pass through the metal.

Only B is true, A, C and D are false.
Explanation:
Gamma radiation is where a nucleus has excess energy and is an excited state. The nucleus can get rid of the excess energy by emitting a high energy photon which is a gamma ray.
Answer A is incorrect. A transmutation reaction changes the number of protons in the nucleus thus transmuting the nucleus from one element into another. Gamma decay doesn't change the number of protons.
Answer B is correct. The emission of the gamma ray photon allows the nucleus to lose excess mass-energy.
Answer C is incorrect. Alpha decay involves the nucleus emitting two protons and two neutrons in the form of an alpha particle which is a Helium nucleus.
Answer D is incorrect. Beta decay occurs when the weak force causes a neutron to decay into a proton, an electron and an electron antineutrino. It can also cause a proton to decay into a neutron, a position and an electron neutrino. The electron emitted is the beta particle.
To complete the picture, neither alpha nor beta decay emit a gamma ray photon during the reaction. After alpha or beta decay have occurred, the nucleus often has an excess of energy. It is quite common for a nucleus to undergo gamma decay after alpha or beta decay.
So, only answer B is correct as stated.
