What to do if you are shot by radiation?

The biological effects of radiation depend on the amount of radiation energy absorbed by the tissue and the sensitivity of the tissue to radiation. The sensitivity of the tissues of each system to radiation is, in descending order: germinal epithelial cells of the testes, hematopoietic cells, intestinal epithelial cells, and basal cells of the skin. Lethal or sublethal doses of systemic irradiation cause extensive bone marrow and intestinal cell death. A small percentage of patients who survive the first 3 to 6 weeks have a gradual increase in the number of surviving stem cells in the body, and eventually the bone marrow cells increase and return to normal function. However, in most people, the stem cells are permanently damaged and regeneration is incomplete, resulting in chronic hypoplasia of the bone marrow and a decrease in red blood cells, granulocytes, and platelets in the blood. Radiation also damages the "stem cells of the vascular system," altering the microenvironment of the blood vessels or damaging the stromal cells in the bone marrow, thus interfering with the regeneration of bone marrow cells.

The most sensitive cells of the bone marrow to acute radiation are young red blood cells, followed by granulocytes and megakaryocytes. Radiation may have a direct or indirect "lytic" effect on lymphocytes and alter their genes.

Prolonged exposure to radiation in small doses can also cause aplastic anemia

- Ionizing radiation on biomoleculesBiological effects of ionizing radiationThe biological effects of ionizing radiationThe biological effects of ionizing radiation are collectively referred to as the biological effects of ionizing radiation. Radiation damage in humans is a serious pathological radiation biological effect. The first section of the role of ionizing radiation on biological macromolecules I. Ionizing radiation on the role of biological macromolecules of the basic principle of biomolecular damage is the basis of all radiation biological effects of matter. And biomolecular damage and free radicals are closely related to the generation. Free radicals (freeradical) refers to some independent existence, with one or more unpaired electrons of atoms, molecules, groups or ions. Free radicals are the biggest characteristic of chemical instability and high reactivity, the life is very short, -OH (hydroxyl radical) the average life of 10-9 ~ 10-8s, biological molecules, free radicals are also mostly in 10-6 ~ 10...

How to avoid the interference of electromagnetic waves

1, in the first three months of pregnancy and after pregnancy, in the following positions must pay attention to self-protection of pregnant mothers working, it is best to be able to leave the post for a period of time: 1) in the high-voltage lines, substations, TV stations, radio stations, radar stations, electromagnetic wave towers and other work; 2) the frequent use of electronic equipment, medical equipment, office automation equipment 3) work in the modern electrical automation environment. 2, each time the computer operation, can not work too long, and should not be carried out continuously intense operation, at the same time, do not keep a fixed position for a long time, and can not sit still for a long time. Usually work half an hour to 1 hour appropriate, at the same time, should pay attention to appropriate rest and activities, because of mental overstress and fatigue, will increase the fetal baby growth and development abnormalities and the possibility of miscarriage of pregnant mothers. 3, the use of electrical appliances, and maintain a certain distance is the most scientific method of protection. Such as operating a computer, the body must be and monitor to keep 100 centimeters ...
