The powerful nature of gamma rays have made them useful in the sterilization of medical equipment by killing bacteria. They are also used to kill bacteria and insects in foodstuffs, particularly meat, marshmallows, pie, eggs, and vegetables, to maintain freshness.

Due to their tissue penetrating property, gamma rays / X-rays have a wide variety of medical uses such as in CT Scans and radiation therapy (see X-ray). However, as a form of ionizing radiation they have the ability to effect molecular changes, giving them the potential to cause cancer when DNA is affected.

Despite their cancer-causing properties, gamma rays are also used to treat some types of cancer. In the procedure called gamma-knife surgery, multiple concentrated beams of gamma rays are directed on the growth in order to kill the cancerous cells. The beams are aimed from different angles to focus the radiation on the growth while minimising damage to the surrounding tissues.

Gamma rays are also used for diagnostic purposes in nuclear medicine. Several gamma-emitting radioisotopes are used, one of which is technetium-99m. When administered to a patient, a gamma camera can be used to form an image of the radioisotope's distribution by detecting the gamma radiation emitted. Such a technique can be employed to diagnose a wide range of conditions (e.g. spread of cancer to the bones).

Gamma ray detectors are also starting to be used in Pakistan as part of the Container Security Initiative (CSI). These US$5 million machines are advertised to scan 30 containers per hour. The objective of this technique is to pre-screen merchant ship containers before they enter U.S. ports.

gamma ray is a packet of electromagnetic energy--a photon. Gamma photons are the most energetic photons in the electromagnetic spectrum. Gamma rays (gamma photons) are emitted from the nucleus of some unstable (radioactive) atoms

Gamma emitting radionuclides are the most widely used radiation sources. The penetrating power of gamma photons has many applications. However, while gamma rays penetrate many materials, they do not make them radioactive. The three radionuclides by far most useful are cobalt-60, cesium-137, and technetium-99m.

cancer treatment
measure and control the flow of liquids in numerous industrial processes
investigate subterranean strata in oil wells
measure soil density at construction sites
ensure the proper fill level for packages of food, drugs and other products.
Uses of Cobalt-60:
sterilize medical equipment in hospitals
pasteurize certain foods and spices
treat cancer
gauge the thickness of metal in steel mills.
Uses of Technetium-99m:
TC-99m is the most widely used radioactive isotope for diagnostic studies. (Technetium-99m is a shorter half-life precursor of technetium-99.) Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies.

In manufacturing, gamma radiation from cobalt-60 or cesium-137 can improve the physical characteristics of materials. For example, exposure to gamma radiation improves the durability of some wood and plastic composites. Treated materials can be used for flooring in high-traffic areas of department stores, airports, and hotels, because they resist abrasion and ensure low maintenance.

Another process, industrial radiography, uses gamma radiation to inspect metal parts and welds for defects. A sealed radiation source, usually iridium-192 or cobalt-60, beams gamma radiation at the part. Any gamma radiation passing through a crack or incomplete weld exposes special photographic, or radiographic, film. (The process is similar to taking an x-ray of a broken arm.) For example, manufacturers use radiography to inspect jet engine turbine blades.

In Popular Culture
Exposure to gamma rays transformed the scientist Bruce Banner into the Incredible Hulk in the Marvel comic of the same name; many of the Hulk's villains and allies also attained their superpowers through this method. It is a recurring theme in Marvel stories that mutations caused by gamma radiation often unleash some hidden aspect of the affected person's psyche; for example, the raging Hulk is a manifestation of Banner's repressed emotions and violent tendencies stemming from an abusive childhood. In his ending of the non-canon Marvel Super Heroes vs. Street Fighter, The Hulk theorizes that gamma radiation caused Blanka's mutations, as they did his. [2]
In both Gundam Seed and Seed Destiny gamma ray technology is incorporated in the space cannon G.E.N.E.S.I.S.
In David Weber's Honorverse, grasers are powerful gamma-radiation-powered energy weapons.
Metroids, creatures in the popular series of the same name, go through a large metamorphosis when exposed to gamma-radiation.
EVE Online, a space-based MMORPG, has a group of weapons technology that uses various EM radiations as lasers, some of which are gamma lasers.
