Step-by-step explanation:
Gamma, alpha and beta particles are used in medicine for the treatment of various kinds of cancers and tumors. In addition gamma rays are used for sterilization in medicine as well as in medical diagnosis.
Alpha particles are used to eliminate static electricity in industry. Beta particles are used in industry as tracers and for monitoring the thickness of materials. Gamma rays are very useful in industry for non destructive testing of products.
In military, alpha and beta particles are used for remote sensing. Gamma rays are useful for nuclear warfare.
Although gamma rays are able to penetrate the human body and cause a lot of damage to tissue and DNA, they are equally able to kill malignant cells in the body. This has been harnessed in radiotherapy for cancer treatment. Gamma rays are indeed dangerous to the human body if they are not delivered carefully and purposefully.
In conclusion, gamma rays are both helpful and harmful when used in medicine. They are helpful when delivered carefully with a specific purpose in mind and harmful when they are not delivered carefully.
