What adverse effects will radioactive substances cause after entering the human body?
Radioactive substances can enter the body through inhalation, digestion and absorption of skin wounds and gastrointestinal tract, resulting in internal irradiation. The external radiation source can penetrate a certain distance and be absorbed by the human body, so that the workers suffer from external radiation damage. Symptoms of radioactive diseases include. Fatigue, dizziness, insomnia, skin redness, ulcer, bleeding, alopecia, septicemia, nausea and vomiting. Sometimes it will increase the incidence of cancer, bacteria and hereditary diseases, endangering the physical and mental health of generations. Generally speaking, the greater the radiation energy received by the human body, the more serious the symptoms of radiation diseases, and the higher the risk of carcinogens and fetal malformations.
Radioactivity is very harmful to microorganisms. Radiation injury includes subacute injury and diffuse injury. If people are exposed to excessive X-rays in a short period of time, the whole body radiation and neutron radiation will cause subacute injury. Mild depilation, sensory organs and other discomfort. In severe cases, the muscles of the whole body twitch, which can lead to epileptic tendon contracture.
The colon with abundant cell metabolism is very sensitive to electromagnetic radiation. If exposed to radiation, the disintegration and inhibition of squamous epithelial cells will soon lead to the destruction of lymphoid tissue. Be careful of electromagnetic radiation, which means that radiation will lead to chromosome transformation of reticulocyte. In chromosome variation, two chromosomes and three-dimensional rings are used.
What harm will radioactive substances do to body tissues and blood after entering the human body?
Diffuse injury after radiation will also lead to large-scale sepsis and increase the incidence of various cancers. Radioactive element atoms are released during the whole nuclear decay process? 、? 、? Radiation, also called radioactivity. Environmental pollution caused by radioactive substances is called radioactive environmental pollution. The sources of radioactive environmental pollution include radioactive waste discharged by nuclear energy industry, nuclear test and settlement of diagnosis and treatment, sewage, organic waste gas and scientific research of radioactive waste.
Radioactive substances in the environment can enter the human body in many ways. Their radiation will destroy macromolecular types in human body, and some will directly destroy somatic cells and tissue structures, causing harm to the body. High-toughness radiation sources can burn the skin, lead to sepsis and various cancers, destroy people's reproductive professional skills, and even lead to death. A small amount of accumulated radiation can also lead to radiation diseases, invading hematopoietic organs, endocrine system, central nervous system and nervous system. The whole process of disease usually lasts for decades.
