Gamma Decay – Class 12 | Chapter – 13 | Physics Short Notes Series PDF for NEET & JEE

Gamma Decay: Gamma decay, also known as gamma radiation, is a type of radioactive decay that involves the emission of high-energy electromagnetic waves known as gamma rays. Gamma rays are the most energetic form of electromagnetic radiation, with frequencies higher than those of X-rays.

Gamma decay occurs when a nucleus is in an excited state and releases energy in the form of a gamma ray to return to a lower energy state. This process does not change the atomic number or mass number of the nucleus. Gamma decay typically occurs in conjunction with alpha or beta decay, as the energy released in these processes can excite the nucleus to a higher energy state.

Applications of Gamma Decay

Gamma rays are highly penetrating and can pass through many materials, making them difficult to shield. They can cause damage to living tissue and are a significant hazard in radioactive materials. However, gamma rays also have several important applications, including:

  • Medical imaging: Gamma rays can be used in medical imaging techniques such as single-photon emission computed tomography (SPECT) and positron emission tomography (PET).
  • Radiation therapy: Gamma rays can be used to treat cancer in a process called radiation therapy. High-energy gamma rays are targeted at the tumor, causing damage to the cancer cells and preventing them from growing.
  • Industrial applications: Gamma rays can be used to inspect welds, detect flaws in materials, and measure the thickness of materials in industrial settings.
  • Nuclear physics research: Gamma rays are an important tool in nuclear physics research, as they can be used to study the properties of atomic nuclei and subatomic particles.
