External to the body, alpha is not dangerous because it is easily stopped by the skin, but it becomes dangerous if ingested because it can then access internal sensitive organs directly.
For electromagnetic radiation, visible light and infra-red are the least damaging. Ultra-violet causes sunburn)
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
Ultra Violet.
it is one kind of rays whic is very harmful and effetive for the livingthings
All high frequency radiation e.g. X rays , gamma rays etc. are harmful to living things .
Evil animals, like evil spiders and rats
A definition for poison is something that can be harmful, unpleasant, and fatal. Radiation can be harmful therefor radiation could be a poison.There is something called acute radiation syndrome which is also called radiation poisoning. This occurs when there is destruction of living tissue due to the effects of being exposed to high levels of radiation.
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
There are a number of types of radiation that can cause mutation in humans.Gamma radiation is probably the one you were thinking of, but ultraviolet radiation can also cause mutation.Pretty much any kind of radiation that causes mutation will almost always cause cancer, as a result.
Wasp is very harmful to humans, so keep your distance if you see a nest in your house and immediately contact a professional to remove it. If you're in Ontario, contact The Critter Guy.
This depends on the kind of radiation. Most electromagnetic radiation is harmless (e.g. broadcast radio) or only very slightly harmful (e.g. microwave, infrared, and visible light can cause heating of materials and thus thermal changes). However very high energy electromagnetic radiation (e.g. ultraviolet, x-ray, gamma ray) and the particulate radiation of radioactive decay and cosmic rays has enough energy to break the bonds holding molecules together, causing chemical changes.
NO because it's tail fibers will allow it to land only on certain a kind of bacteria and not on human cells.
It depends what kind of bacteria you're talking about. Our bodies naturally contain bacteria that helps us digest food.
