Long-term effects of radiation exposure on health

Delays in the effects on the human body due to radiation exposure to ionizing radiation have been determined by long-term epidemiological studies. A cohort study (lifespan survey) of atomic bomb survivors in Hiroshima and Nagasaki is considered the most reliable source of information for cohort size, exposure to men and women of the general population and all ages. And various doses individually evaluated. Therefore, the life survey is the basis of the risk assessment of the radiation protection system by the International Radiation Protection Committee and other authorities. Radiation exposure increases the risk of cancer throughout life and is essential for continued follow-up of survivors. Overall, survivors have significant radiation-related cancer risk, and those exposed to children are at a higher risk of developing radiosarcoma than children over older adults. At high doses and in some cases at low doses, radiation can increase the risk of cardiovascular disease and other non-cancerous diseases. The genetic impact of children of atomic-bomb survivors has not been discovered yet. For radiation protection purposes, dose response relationships for low dose cancers are assumed to be linear without a threshold, but are not clearly shown. This outstanding problem is not only a matter of proper treatment of potential health consequences of nuclear accidents like Fukushima and Chernobyl but also issues of occupational and medical exposure. It is therefore necessary to establish a dose response relationship for an appropriate low dose radiation effect.

Exposure to very high levels of radiation such as near atomic explosions can cause serious health effects such as skin burns and acute radiation syndrome ("radiation injury"). It can also cause long-term health effects such as cancer and cardiovascular disease. Exposure to low-level environments does not immediately affect health, but they are a small factor of our overall cancer risk. A very high radiation exposure is required to cause acute radiation syndrome - US units of more than 75 radrads are used to measure the amount of radiation absorbed (the amount of radiation absorbed by the object or person). The equivalent internationally is gray (Gy). One hundred radians is equal to one gray. (0.75 gray gray is the international unit used to measure the absorbed dose (the amount of radiation absorbed by an object or a person), the absorbed dose unit in the United States is rad, 1 gray corresponds to 100 rad. In a short time (several minutes to several hours)

In the biological impact of radiation, our health and our body have many dangerous effects. The biological effects of radiation are generally divided into two categories. The first category involves exposure to high doses of radiation over an extended period of time, resulting in acute or short-term effects. The second category is long-term exposure to low-dose radiation, resulting in chronic or long-term effects. Skin effect includes (redness like sunburn), dry (peeling), and moist (foaming). Skin effects are more likely to occur when exposed to low energy gamma rays, x-rays, or beta rays. The majority of radiation energy accumulates on the surface of the skin. The dose required for erythema is relatively high, there are over 300 radiation. Foam requires more than 1,200 doses of radiation

There is no safe radiation exposure level. Radiation exposure at each dose increases the likelihood of developing cancer or other health effects, but it takes a long time to develop cancer. Exposure to a carcinogen can actually take 10, 15, 20 or more years to cause a disease, making people easy to lose contact with radiation as a cause. In the case of childhood cancer, the mother or fetus in the uterus may be exposed to this condition. Radiation exposure is more effective than adult because children grow and cells rapidly divide.
