Ingestion of the short-lived isotope iodine-131, with its well-known risk of thyroid cancer when absorbed in the thyroid glands of children and young people, was the only major radiation-related health effect of the Chernobyl accident on the public.
FORBES: Like We've Been Saying -- Radiation Is Not A Big Deal
They also conclude that greenhouse warming has partially been offset by the cooling effect of aerosols - tiny particles of dust thrown into the atmosphere that can reflect solar radiation back into space.
Most of it is, of course, radiated back into space. (It is the partial blocking of this radiation by gases such as carbon dioxide that causes the much-talked-of greenhouse effect.) Some of it, however, goes in the opposite direction, into the ground.
While ice reflects around 80 percent of the sun's heat, having a cooling effect, blue sea water can absorb up to 95 percent of solar radiation, warming up the sea and accelerating the melting process further.
The effect of increased brain activity in children because of cell phone radiation is another area yet to be studied.
They were then able to give the mice higher doses of radiation therapy with no ill effect by blocking a mechanism by which endothelial cells communicate with each other.
Ripples in this radiation are, in effect, fossils that reflect patterns of sound in the early universe.
Doses of radiation received by people near the damaged power plant were so low that no discernible health effect could be expected.
FORBES: Like We've Been Saying -- Radiation Is Not A Big Deal
While each phone produces radiation that bounces around the car, the passengers absorb some of it, which has the effect of reducing the overall intensity, just as the presence of an audience changes the acoustics of a concert hall, making it less reverberant.
But the strength of the greenhouse effect depends on the chemical composition of the atmosphere, because the phenomenon is due to the absorption of infra-red radiation by various gases in the air.
