Application of Gamma Rays

Usage of gamma rays in medical treatment

  • Gamma rays are ionizing radiation which can kill living cells. They are used to treat malignant tumours in radiotherapy. For treatment deep within the body, high energy photons are sent to reach the target tumour without affecting the surrounding tissue. Though x-rays are also ionising radiation, because of the lower energy compared to gamma rays, they may fail to reach sufficiently deep into the body and may cause instead damage to the surrounding tissues that absorbed them.
  • Gamma rays can also act as surgical knifes in surgery.
