High intensity UV radiation?
High Intensity UV radiations are the UV-C ones. They are the most dangerous as well.
Why gamma rays harmful to human not microwaves?
-- Gamma rays are harmful to living organisms because each gamma-ray photon carries relatively high energy, and is capable of damaging cells. -- You should be suspicious of whoever told you that microwave radiation is not harmful to humans. Have you ever seen what 1,200 watts of RF at 2.5 GHz can do to a hot dog in the 'microwave' oven ?
How do microwave oven cook what is the nature of radiation in microwave ovens?
It is radio waves, at the frequency of 2.45 GHz, and very high power.
Ultraviolet rays are potentially harmful to us primarily due to their?
d. intensity
Ultraviolet rays are potentially harmful to us due to their intensity. amplitude. high frequency or long wavelength?
High Frequency.
What are the dangers of microwave radiation?
In general, microwaves are harmful if they are very powerful and concentrated. All of our ordinary microwave-emitting devices are perfectly safe to use because they are very low power. A microwave oven doesn't release enough of the energy to cause harm when the door is properly closed - hence, a microwave that functions with a door open could be potentially harmful. Very powerful microwaves are harmful because they cause burns. Microwave radiation, despite popular claims, does not cause cancer or any other illness associated with exposure to ionizing radiation. Microwaves from cell phones, for example, are not powerful and concentrated enough to cause harm. In themselves, other than high power exposure - several kilowatts - that's many more times than what is inside an operating microwave oven, microwaves are not dangerous. However, injuries can occur from overheated foods - burns, scalds, eruptions and fires.
What is more dangerous high frequency radiation or low frequency radiation?
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 :)source: Is_electromagnetic_radiation_harmful_to_humans
Why is radiation harmful to both living and nonliving things?
This depends on the kind of radiation. Most electromagnetic radiation is harmless (e.g. broadcast radio) or only very slightly harmful (e.g. microwave, infrared, and visible light can cause heating of materials and thus thermal changes). However very high energy electromagnetic radiation (e.g. ultraviolet, x-ray, gamma ray) and the particulate radiation of radioactive decay and cosmic rays has enough energy to break the bonds holding molecules together, causing chemical changes.
Does the radiation from a microwave affect a television if the television is placed on top of the microwave?
It could, althought it may just be from the high-voltage power supply working correctly.
Can infrared radiation kill you?
Yes. At a high enough intensity any form of radiation can be deadly. All forms of electromagnetic radiation carry energy, which can heat objects. Intense enough infrared radiation can essentially broil you.
Is true that if a person is exposed to radiation he has no chance of survival?
No. It depends on the amount of radiation, and it has to be ionizing radiation, which means ultraviolet or shorter waves. Alternatively, non-ionizing radiation can kill by heating the tissues if the energy intensity is high enough.
How is the sun harmful to the planet?
The sun emits high energy radiation and charged particles that are hostile to life. The high radiation causes sun-burn the charged particles cause mutations.
