In females, IR can have long-term effects on fertility, specifically on ovarian insufficiency, pubertal arrest and subsequent infertility. [1] In males, the use of radiotherapy can disrupt the endocrine system leading to altered spermatogenesis and consequently a decrease in sperm count, sperm motility, sperm morphology and sperm viability. [2]
Dose rates high enough to cause the acute form (> ~0.1 Gy/h) are fatal long before onset of the chronic form. The lower threshold for chronic radiation syndrome is between 0.7 and 1.5 Gy, at dose rates above 0.1 Gy/yr. [3] This condition is primarily known from the Kyshtym disaster, where 66 cases were diagnosed.
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level ...
Cumulative effects from this process should not be confused with long-term effects – when short-term effects have disappeared and long-term effects are subclinical, reirradiation can still be problematic. [47] These doses are calculated by the radiation oncologist and many factors are taken into account before the subsequent radiation takes ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Long-term effects of radiation [ edit ] The delayed effects, found 3 months or more after radiation therapy, produce pathology which includes intestinal epithelial mucosal atrophy , vascular sclerosis , and progressive fibrosis of the intestinal wall , among other changes in intestinal neuroendocrine and immune cells and in the gut microbiota .
Radiation-induced secondary malignancy is another very serious adverse effect that has been reported. As there is minimal exit dose when using proton radiation therapy, dose to surrounding normal tissues can be significantly limited, reducing the acute toxicity which positively impacts the risk for these long-term side effects.
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."
