One of the features of the Gamma rays is that they are very penetrating. It is for this reason that they are commonly used in the sterilization of the medical equipment that are disposable.

Gamma radiation is used to sterilize some, but not all medical equipment becks it is very effective and does not damage the equipment on which it is used, nor does it leave a chemical residue. When done correctly radiation sterilization does not put hospital staff at risk.
Cobalt-60 is used for therapeutical irradiation (for cancers), laboratory or industrial irradiation (for example for radiopolymerization), industrial gamma radiography, sterilization of foods, medical equipment, blood and tissues, etc.
Cold sterilization is a process in which sterilization is carry out at low temperature with the help of chemicals, radiations, membranes and all other means excluding high temperature. Ionizing radiation such as x-rays,gamma rays and cosmic rays, cause no appreciable increase in temperature in this method ,it is referred as cold sterilization
Gamma rays are extremely high energy electromagnetic radiation. The source of gamma rays is nuclear "change" like radioactive decay. Radioisotopes, which are either the natural or artificial radioactive isotopes of elements, occur in river deltas, granite, some older paints, some older ceramics, nuclear waste, and specifically irradiated materials that have been made radioactive to be applied to medical devices (like 60Co "pencils" used for medical treatment) or industrial imaging or irradiation sterilization equipments.
The typical use for human-generated gamma radiation is in medical procedures, such as the "gamma knife" cancer therapy treatments.
Usually for killing cancerous tumors, as in radiotherapy. Sometimes also for medical imaging, as in a gamma camera. Generally, Gamma rays are dangerous to living tissue.
X-rays witch is just under the wavelength of gamma rays. gamma rays are deadly though

alpha decay, beta decay, and gamma radiation
Cancer treatment, industrial imaging, sterilization of food & surgical instruments are just a few of the myriad of applications for gamma rays. remember, gamma rays are produced primarily during the decay of certain radioisotopes and although not unlike x-rays, are not produced in the same fashion. Cobalt 60 has been used to provide a gamma source for radio-graphic imaging in nondestructive testing of pipe welds.
