heya. Okay so I had the same question for a sheet i had to do in my physics lesson.
The harm done to humans by EM radiation depends on the intensity and wavelength of the radiation.
high frequency radiation has more potential to damage human DNA than longer wavelengths (Low frequency). That's why UV radiation tends to promote skin cancer while visible light has no known tendency to do so. Short-wavelength radiation can also carry more energy than long-wavelength radiation of the same intensity.
Long-wavelength radiation is more known for its tendency to cause human tissue to heat up, which can cause death more quickly than short-wavelength radiation. Microwave energy is one example of this; fairly high-intensity microwaves are used to heat food in a microwave oven.
So really high frequency is more dangerous, such as gamma rays :)

What is the difference between nuclear radiation and heat radiation?
Heat radiation is infrared radiation, which is a relatively low frequency radiation, slightly lower than that of visible light. Nuclear radiation includes a variety of types, including X rays and gamma rays, which are very high frequency radiation, and which are consequently much more dangerous, and can cause radiation sickness. There are also other types of nuclear radiation such as alpha rays, beta rays, and neutrons, all of which are in the form of subatomic particles rather than electromagnetic radiation.
Can the electromagnetic radiations be used in hospitals?
Yes. Electromagnetic radiation has many uses in hospitals. As you might know the electromagnetic spectrum goes from low frequency (radio waves) to high frequency (gamma waves). High frequency waves carry more energy and penetrate through matter more easily than low frequency waves, this is why nuclear reactors are protected by so much concrete. In hospitals doctors use machines that typically use high frequency waves. These high frequency waves are much higher than the waves used in radios and telecommunications and can sometimes be dangerous if you are exposed for long periods of time however hospitals have found many uses for electromagnetic radiation. For example x-rays are used because they penetrate through the body and can be detected by computers which create images of the inside of a person's body. Gamma rays are usually used for cancer patients because doctors hope the radiation will kill the cancer cells before they kill the patient. Machines such as magnetic resonance imaging (MRI s) use magnetic fields and electromagnetic radiations to create images of the body that can't be seen by x-rays. Though these machines can be dangerous if misused they allow doctors to save many lives.
Does a high frequency wave transmit more energy than a low frequency wave?
no.
The various types of electromagnetic radiation are distinguished from each other by their?
Electromagnetic waves are classified according to their wavelength and frequency and this classification is called electromagnetic spectrum.
How does Ultraviolet light work?
UV light is the same as any other kind of light or radiation along the spectrum from radioactive waves to radio waves. The difference between them is their wavelength and fequency. The longer the wavelength, the less the frequency. UV light is high-frequency short-wavelength light, just a bit more high-frequency than the highest-frequency visible light, which is violet. How does light work? Well, even physicists aren't quite sure.

Are loud sounds dangerous?
actually,yes!!!! your ear can go deaf for example you listen to music really loud on your ipod or anything like that it can damage inside your ear.you could still hear but barley!!!!!!!!!!!!!! SO DON'T DO IT

Are X-rays less dangerous to health than ultraviolet radiation?
No, they are not. X-rays have a higher energy than UV radiation, and they have the potential to do more damage to tissue.
What is more dangerous high diastolic or high systolic?
Having a high systolic bp is more dangerous than high diastolic bp.
One type of radioactive device that indicates the intensity of radiation with a clicking sound that increases in frequency as more radiation is present is a?
A geiger counter.
Why are the sun's rays more dangerous on the moon than on earth?
Because the Moon has no atmosphere to filter out dangerous radiation.
Which has more energyinfrared or ultraviolet radiation?
Ultraviolet with its higher frequency and shorter wavelength carries more energy then infrared.
What are more dangerous low frequency radiation?
Cell phone, and wifi is the most dangerous, because of the greed to make money. Brain doctors don't use them because they know of the brain tumor they cause... see Dr. Marcola.com. The FDA is paid off by the big greed Lobbist.
What type of radiation is probably the most dangerous to humans?
Externally, gamma radiation is dangerous because it can penetrate the body. Alpha is most dangerous if ingested.
What are the infra red radiation sources?
Anything that has a temperature emits IR radiation. Hotter things emit more at a higher frequency. Then they become Red.
Compared to visible light ultraviolet radiation is more harmful to human skin and eyes because ultraviolet radiation has a?
higher frequency... resonance with DNA
