Because a dose greater than 6 Gy to the whole body are generally not treatable and usually lead to death within two days to two weeks.With Gy of course refering to a unit called gray which is used to measure the amount of absorbed radiation.
=============================
Radiation is like bullets. Just like bullets the radiations also pierce through your flesh causing damages to wherever it passes through. And like poison laced bullets can cause damages to the rest of your body which we refer to as cancer. But you wont be able to see this as these bullets are too small to be seen by the naked eye. They are composed of alpha beta and gamma radiations. Read about them as well.
Yes, according to Kirchhoff's law of thermal radiation, good absorbers are good emitters of radiation at a given wavelength. This means that materials that efficiently absorb incoming radiation also emit radiation effectively at the same wavelength.
A good absorber of radiation is a good emitter. Radiation is the energy that that comes from a source and travels through space or through something. Some examples of radiation include light, heat and sound.
Well, honey, let me break it down for you. A good absorber of radiation is also a good emitter. It's like a give and take relationship - what goes in, must come out. So, if something sucks up radiation like a sponge, you can bet your bottom dollar it's gonna spit it back out just as well.
Materials that are good absorbers of radiation are also good emitters of radiation. This is known as Kirchhoff's law of thermal radiation. Good absorbers like black surfaces are also good emitters, while poor absorbers are poor emitters. This is why black objects heat up quickly in the sun and cool down quickly at night.
The heat we feel from the sun is transferred to us primarily through radiation.
Radiation helps us cook our food!!
Because it protects us from the suns harmful rays/radiation.
What can radiation do to us?
-- 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.
An object is a good emitter of radiation if it is a good absorber of radiation.
The good about radiation is it can stop the abnormally growing cells in cancer,and radiation will let us visuallized the entire human body. Disadvantage with radiation when in great amount can cause sterility.
When it is in the stratosphere it is good for use as it blocks a portion of the sun's ultraviolet radiation. When it is at the surface it is bad for as, as it is an irritant.
Ultraviolet radiation.
no
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
