The answer depends on what type of radiation and how much. Small amounts of infra-red radiation will make you feel warm, large amounts will burn you. Visible light has little effect. Small amounts of some ultra violet radiation will help you synthesise vitamin D and also give you a tan. Large amounts will cause sun burn and is likely to lead to skin melanomas and cancers. Absorbing more powerful radiation - such as gamma waves - is much more likely to cause cancers and lead to genetic mutations.
It's because: they emit such small amounts of thermal radiation. The radiation is energy, and energy is a form of mass.
Background radiation - is the 'natural' radiation of the Earth. There are radioactive ores naturally present in the ground that give off small amounts of radiation. This is detectable by instruments, but is of no consequence to humans or animals.
Yes. studies have shown that small amounts of micro wavelengths are in human urine.
Yes, the sun rays contain dangerous amounts of Ultra-violet radiation that can hurt your eyes and your skin.
Sand is not good to eat. Small amounts won't hurt.
Electromagnetic radiation is made of energy. Very small amount of energy for radio waves or large amounts of energy for gamma rays. Visible light is electromagnetic radiation.
It does, but in very small amounts because it is absorbed by Earths atmosphere. The ozonosphere blocks most of the UV radiation from striking the surface of earth.
Radioactive materials(uranium, thorium and radium) exist naturally in soil and rock.
Small amounts of radiation from damaged nuclear plants in Japan have already reached California but they pose no health threats at all. Any radiation that reaches California from Japan is well dissipated by the time it gets there.
yes there is extreme amounts of gamma radiation in in nuclear bombs
Alpha radiation is absorbed by a sheet of paper; beta radiation is absorbed by a person; gamma radiation is absorbed by a stell wall. However, small amounts of gamma radiation can still be absorbed by a person.
