Gamma rays can be used in various activities, such as; treatment of cancer through radiation, fluid flow tracking, searching for natural resources, sterilization of medical equipment, and geodetic mapping. All of these activities take advantage of the properties of gamma rays that have very high energy and further range power.

Just like X-rays, gamma rays can also pass through almost any material. Gamma ray radiation is measured in millirem (mrem). Based on observations, every normal environment at least exposed to radiation exposure of 25 mrem.

Radiation exposure increased to 5 thousand mrem which is felt by many people working in a radioactive environment with a maximum level of protection. The normal threshold of the radiation exposure level is set at 10 thousand mrem. If it exceeds this limit, it will have a tremendous health impact as happened to radiation sufferers due to nuclear bombs dropped on Japan during World War II. Gamma rays can have tremendous health effects, such as: Can cause cancer, such as skin and bone cancers, damage to body cell tissue, and genetic mutations affecting the generation to be born
