Most of our exposure to radiation, about 97%, is in the form of natural background radiation. This can be from such sources cosmic rays and naturally occurring radioactive isotopes, such as the very common (and not particularly radioactive) potassium-40, which is 0.012% of all potassium.
The rest of the nuclear radiation comes from medical isotopes, fallout from nuclear bombs, and the Chernobyl and Kyshtym disasters. We also get x-rays, and UV light from the sun, both of which are ionizing.
no because of the high radiation it causes. its illegal in the US and many other countries
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
hi It protects us from the Sun's radiation and protects us from the serious damage that is caused by the exposure. It also protects us from various skin diseases. It also maintains an equilibrium in the nature.
-- Radiation at frequencies below 1.7 MHz is good because it helps us hear the news on AM radio. -- Radiation at frequencies between 88 and 108 MHz helps us hear music on FM radio. -- Radiation at frequencies around 1 GHz helps us make cell phone calls. -- Radiation at frequencies around 2.45 GHz helps us heat meatloaf and make popcorn, and it can't hurt us if we're careful with it. -- Radiation with wavelengths between 400 and 800 nanometers is good because it helps us see things so that we don't go around bumping into them. -- Radiation with wavelengths between 300 and 400 nanometers can give our skin a nice healthy glow, and it can't hurt us if we're careful with it. -- Radiation with wavelengths between 100 and 300 nanometers can help the doctor check our bones, and it can't hurt us if we're careful with it. -- Radiation with wavelengths less than maybe 350 nanometers can hurt us if we're not careful with it.
Clothing, sunscreens, and building materials like glass can protect us from infrared radiation by reflecting or blocking it. Additionally, our skin provides some natural protection from infrared radiation by absorbing and dissipating it as heat.
The study of radiation effects is important because it helps us understand how radiation exposures can impact human health and the environment. This knowledge is essential for developing safety guidelines, radiation protection measures, and medical treatments involving radiation. It also helps in assessing and mitigating the risks associated with nuclear accidents, medical procedures, and space exploration.
Permissible exposure limits are levels of exposures permitted by OSHA, the US Occupational Safety and Health Administration.

What can radiation do to us?
Ultraviolet radiation.
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
The radiation standards is very important to us in our daily lives!!! The radiation standards is very important to us in our daily lives!!! The radiation standards is very important to us in our daily lives!!! The radiation standards is very important to us in our daily lives!!!
Radiation helps us cook our food!!
The ozone protects us from much UV radiation. It is present as ozone layer.
It can very often. It's iron that helps us metabolize food. An extremely anemic person could have a very serious case of diarrhea.
Infrared radiation is the component of sunlight responsible for heat. When sunlight hits an object, the object absorbs some of this infrared radiation, which causes its temperature to rise and gives us the sensation of warmth.
look at Japan.
