Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans. High doses of ionizing radiation can cause damage to living tissue such as radiation burning and harmful mutations such as causing cells to become cancerous, and can lead to health problems such as radiation ...
It is unknown whether high-LET radiation could cause the same types of tumors as low-LET radiation, but differences should be expected. [9] The ratio of a dose of high-LET radiation to a dose of x-rays or gamma rays that produce the same biological effect are called relative biological effectiveness (RBE) factors. The types of tumors in humans ...
The reported health effects are consistent with high doses of radiation, and comparable to the experiences of cancer patients undergoing radio-therapy [15] but have many other potential causes. [14] The effects included "metallic taste, erythema, nausea, vomiting, diarrhea, hair loss, deaths of pets, farm and wild animals, and damage to plants."
Dose equivalent calculates the effect of radiation on human tissue. [4] This is done using tissue weighting factor, which takes into account how each tissue in the body has different sensitivity to radiation. [4] The effective dose is the risk of radiation averaged over the entire body. [4] Ionizing radiation is known to cause cancer in humans. [4]
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
The loss of human population in Chernobyl, sometimes referred to as the "exclusion zone," has allowed the ecosystems to recover. [9] The use of herbicides, pesticides, and fertilizers has decreased because there is less agricultural activity. [9] Biodiversity of plants and wildlife has increased, [9] and animal populations have also increased. [9]
Radiation-induced cancer, teratogenesis, cognitive decline, and heart disease are all stochastic effects induced by ionizing radiation. Its most common impact is the stochastic induction of cancer with a latent period of years or decades after exposure. The mechanism by which this occurs is well understood, but quantitative models predicting ...
Radiation tests in model organisms that determine the effects of high radiation on animals and plants are: [18] Chromosomal aberrations. DNA damage. Cancer, particularly leukemia. [2] Leukopenia. Growth reduction. Reproductive deficiencies: sterility, reduction in fecundity, and occurrence of developmental abnormalities or reduction in ...
