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.
What else can I help you with?
Is uranium used widley today?
no because of the high radiation it causes. its illegal in the US and many other countries
What layer protects us from what kind of radiation?
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
How ozonosphere protect us?
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.
Is all radiation harmful What if any are some good forms of radiation?
-- 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.
What protects us from infrared radiation?
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.
What is the Importance of the study of radiation effects?
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 mandated by?
Permissible exposure limits are levels of exposures permitted by OSHA, the US Occupational Safety and Health Administration.
Is uranium used widley today?
no because of the high radiation it causes. its illegal in the US and many other countries
What does the far end of infared radiation do for us?
What can radiation do to us?
What type of radiation does the ozone protect us from?
Ultraviolet radiation.
What layer protects us from what kind of radiation?
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
Define accounting standards?
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!!!
What are good forms of radiation?
Radiation helps us cook our food!!
What protects us from too much UV radiation?
The ozone protects us from much UV radiation. It is present as ozone layer.
Do low iron causes you to have diarrhea?
It can very often. It's iron that helps us metabolize food. An extremely anemic person could have a very serious case of diarrhea.
What component of sunlight is responsible for heat?
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.
How can radiation help us?
look at Japan.
