Gamma rays have both favorable and unfavorable effects on the human body. Gamma rays are a kind of rays released by atomic nuclear energy in the process of constant jump metamorphosis, which are very penetrating and energetic.
The advantages of gamma rays are mainly in the medical field, it can help to kill the cells, against the cancer cells treatment has some effect. The disadvantages of gamma rays are that they have high energy and penetrating power, which can easily cause DNA breaks in the cells of living organisms, leading to cell mutation and loss of hematopoietic function, etc. If the amount of gamma radiation is too high, the radiation will not be effective in killing cells.
If the amount of gamma radiation is too large, when it reaches 200~600 rem, the human hematopoietic organs will be damaged, resulting in a large number of white blood cells, internal bleeding, hair loss, and so on. When it reaches 1,000 to 1,500 rem, the human gastrointestinal system will be damaged, resulting in diarrhea, fever, endocrine disorders, etc., which is a serious direct threat to life.
