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.
Radiation therapy at doses around "23.4 Gy" was found to cause cognitive decline that was especially apparent in young children who underwent the treatment for cranial tumors, between the ages of 5 and 11. Studies found, for example, that the IQ of 5-year-old children declined each year after treatment by additional several IQ points, thereby ...
Microwave and other radio frequencies cause heating, and this can cause burns or eye damage if delivered in high intensity, [38] or hyperthermia as with any powerful heat source. Microwave ovens use this form of radiation, and have shielding to prevent it from leaking out and unintentionally heating nearby objects or people.
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases, where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products. High-intensity ionizing radiation in air can produce a visible ionized air glow of telltale
Hypotheses include Cherenkov radiation created as the cosmic ray particles pass through the vitreous humour of the astronauts' eyes, [4] [5] direct interaction with the optic nerve, [4] direct interaction with visual centres in the brain, [6] retinal receptor stimulation, [7] and a more general interaction of the retina with radiation.

The physicians working at Hanford reportedly knew radiation could cause illness, and they used dosimetry devices to monitor workers' exposure. They would wear badges containing photographic film ...
The cause is thought to be thermoelastic expansion of portions of auditory apparatus, and the generally accepted mechanism is rapid (but minuscule, in the range of 10 −5 °C) heating of brain by each pulse, and the resulting pressure wave traveling through the skull to the cochlea.
High-intensity radiofrequency radiation can produce heat and cause elevated body temperatures and even burns, according to the American Cancer Society. More intense rays, like gamma rays and X ...
