Ionizing radiation is harmful to the human body. Human beings on Earth are exposed to natural and artificial radiation all the time. Natural radiation is the main source of radiation; artificial radiation includes medical radiation, nuclear energy production, nuclear explosions and radiation sources added to consumer products. Medical radiation accounts for 98% of artificial radiation and is the main source of artificial radiation. Due to radiation on the human body caused by varying degrees of biological damage, have a certain impact on health. Therefore, strengthening protection is an important measure to reduce the harm.
