Studies have been performed on the use of shortwave radiation for cancer therapy and promoting wound healing, with some success. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues, for example by overheating or inducing electrical currents. [28]
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 ...
Radiation of 100 mGy to the head at infancy resulted in the beginning appearance of statistically significant cognitive-deficits in one Swedish/radiation-therapy follow-up study. [5] Radiation of 1300-1500mGy to the head at childhood was similarly found to be roughly the threshold dose for the beginning increase in statistically significant ...
The goal of space radiation research is to estimate and reduce uncertainties in risk projection models and, if necessary, develop countermeasures and technologies to monitor and treat adverse outcomes to human health and performance that are relevant to space radiation for short-term and career exposures, including acute or late CNS 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."

Some effects of ionizing radiation on human health are stochastic, meaning that their probability of occurrence increases with dose, while the severity is independent of dose. [2] Radiation-induced cancer, teratogenesis, cognitive decline, and heart disease are all stochastic effects induced by ionizing radiation.
In most locations, the levels remained well below the levels required to damage human health, as the recommended annual maximum limit is well below the level that would affect human health. [188] [189] [190] Natural exposure varies from place to place but delivers a dose equivalent in the vicinity of 2.4 mSv/year, or about 0.3 μSv/h.
