The principle of damage to the human body caused by × rays:
The occurrence of radiation damage is a very complex process. When X-rays irradiate the body, they interact with body tissues, cells, body fluids and other substances, causing ionization of atoms or molecules of the material, which can directly destroy certain macromolecular structures in the body, such as Breaking protein molecular chains, ribonucleic acid or deoxyribonucleic acid, destroying some enzymes that are important to material metabolism, etc., can even directly damage cell structure. In addition, rays can ionize the water molecules that exist widely in the body to form some free radicals. Through the indirect action of these free radicals, the body can be damaged, causing a series of biochemical changes, metabolic disorders, and functional disorders in the body tissue. can cause death.
(1) Acute injury: radiation injury caused by a large dose of irradiation to the whole body in a short period of time. Such situations are rare, and only occur when a machine failure is not detected or misused for a long period of time. The clinical manifestations are mainly damage to the central nervous system, hematopoietic system, digestive system and gonads. Such as nausea, vomiting, diarrhea, bleeding, lethargy, hair loss, etc., which can lead to death in severe cases.
(2) Chronic damage: radiation damage that occurs after exposure for several years or decades when exposed to a low dose exceeding the allowable level for a long time. Such injuries are easily caused when operating room staff are often exposed to radiation in their daily work and do not pay attention to protection. Mild clinical manifestations are mainly neurasthenic syndrome and autonomic dysfunction symptoms, such as fatigue, dizziness, headache, tinnitus, sleep disturbance, memory loss, sweating, palpitations, easy to catch colds, bleeding gums, joint pain, etc. Skin damage is mainly manifested as skin, rough nails, hair loss. Reproductive system damage can cause miscarriage, premature birth, stillbirth, teratogenesis, etc. Severe cases lead to leukemia, cancer, aplastic anemia, cataracts, and shortened life expectancy.
Please rest assured that the radiation dose of the DRX machine is small, and the lead room and lead clothing should be prepared when conditions permit. Although the radiation dose of the DRX light machine is small, please take protective measures.
