Gamma decay and its energy level

In summary, gamma rays are electromagnetic waves emitted by nuclei undergoing a transition from an excited state to a lower energy state. This process is similar to the emission of light by atoms and is typically preceded by a different type of decay, such as beta decay. The excited states of nuclei have a short lifetime and are created as a result of previous decays.

Gamma decays are e.m.waves ..then how describe gamma decay in terms of energy levels?

Gamma rays (not decays) are e.m.waves (or rather single photons).

If you think about nuclear gamma decays - you may think about them as an analogue of light emitted by atom. Atom has quantised energy levels and may jump from one to another emitting a photon. The same for nuclei: they may exist in excited state and transition to the state of lower energy is accompanied by emission of the photon.

Excited states of nuclei usually have very short life time (order of 10-12s) and are created in effect of previous decay of other kind (usually beta).
 

1. What is gamma decay?

Gamma decay, also known as gamma radiation, is a type of radioactive decay where an unstable atomic nucleus releases high-energy photons, called gamma rays, to reach a more stable state.

2. How is the energy level of gamma decay determined?

The energy level of gamma decay is determined by the difference in energy between the initial and final states of the atomic nucleus. This energy is emitted in the form of a gamma ray.

3. What is the importance of gamma decay in nuclear processes?

Gamma decay plays a crucial role in nuclear processes as it allows for the emission of excess energy from an unstable nucleus, making it more stable. It is also used in nuclear medicine for diagnostic imaging and cancer treatment.

4. Can gamma decay be harmful to humans?

Yes, exposure to high levels of gamma radiation can be harmful to humans as it can damage cells and DNA. However, small amounts of gamma radiation are used in medical procedures and are generally not harmful.

5. How is gamma decay different from other types of radioactive decay?

Unlike alpha and beta decay, which involve the emission of particles from the nucleus, gamma decay only involves the emission of high-energy photons. Additionally, gamma decay does not change the atomic number or mass of the nucleus, while alpha and beta decay do.
