Ionizing radiation, also spelled ionising radiation, consists of subatomic particles or electromagnetic waves that have enough energy per individual photon

of radiation-induced health effects within a population exposed to incremental doses at levels equivalent to or lower than natural background levels."

to 58,000 km (400 to 36,040 mi) above the surface, in which region radiation levels vary. The belts are in the inner region of Earth's magnetic field.

Russian meteorology service, stated that background radiation levels peaked at 4–16 times normal levels at six of its eight stations in Severodvinsk, 47

Background radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate

month; and about equal at 6 months. Thereafter fission product fallout radiation levels drop off rapidly, so that Co-60 fallout is 8 times more intense than

Radiation hormesis is the hypothesis that low doses of ionizing radiation (within the region of and just above natural background levels) are beneficial

to calculate the biological effects on the human body of certain levels of radiation, and thereby advise acceptable dose uptake limits. The ICRP recommends

particle radiation consisting of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation acoustic

predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing radiation increases
