Radiation can come from a machine outside the body (external-beam radiation therapy) or from radioactive material placed in the body near cancer cells (internal radiation therapy, more commonly called brachytherapy). Systemic radiation therapy uses a radioactive substance, given by mouth or into a vein, that travels in the blood to tissues throughout the body.
radiations are emitted by a radiator,and in some cases a receiver is placed after the body and radiator.
What else can I help you with?
Is a toster a conduction convection or radiation?
A toaster uses primarily conduction and radiation to cook food. Conduction occurs when the heating elements directly heat the bread touching them, while radiation happens when the heat is emitted to cook the outer surface.
Recall that good absorbers are good emitters?
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.
Is a good reflector of radiation a good emitter of radiation?
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.
Does sonogram use radiation?
No, ultrasound used in sonograms does not involve radiation. It uses sound waves to create images of structures inside the body.
Is a good absorber of radiation a good emitter or a poor emitter?
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.
What are uses in medicine for radiation?
Some cancers are treated with radiation.
Good and bad effects of radiation on human health?
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.
Will an infrared port pick up bluetooth?
No, infrared port uses IR radiation and bluetooth uses radio frequency radiation.
Is there any radiation from a game controller?
Pfft. No. It uses Radio Signals. Not Radiation.. Radiation is from the Sun and Microwave Signals. :)
What does conduction and convection uses that radiation does not?
Matter.
An object is a good emitter of radiation if it is what?
An object is a good emitter of radiation if it is a good absorber of radiation.
What are some medical uses of radiation?
to detect radiation, a device such as Geiger- Muller tube is used
What are other helpful uses of radiation?
Other than what?
What are the medical uses of radiation?
To shrink cancerous tumors
What uses heat energy?
Convection,conduction and radiation
Is a toster a conduction convection or radiation?
A toaster uses primarily conduction and radiation to cook food. Conduction occurs when the heating elements directly heat the bread touching them, while radiation happens when the heat is emitted to cook the outer surface.
What are three things that uses sunlight?
Sun Radiation Convection
