Radiation, while it has negative connotations, can also be important for the treatment of some extreme diseases. It also is known to have value in changing chemical molecules, which is important for biological purposes.
The obvious answer is that all the energy that comes to Earth from the Sun (solar energy) comes by radiation. All life on our planet depends on that energy, since plants need it to produce their own energy via photosynthesis. Animals that are herbivores derive their energy from eating those plants, and carnivores and omnivores derive their energy from eating other animals.
Not necessarily. Different kinds of radiation detectors pick up different kinds of radiation. Also some radiation is of so little importance, that detectors are not designed to pick it up. An example here is UV light, which is actually low level ionizing radiation. One more thing: Radiation doesn't require air to travel. A quick example: The sun's radiation reaches earth, yet there is no air in space for it to travel through.
The single biggest benefit to the Earth's magnetic field is that it shields the Earth's surface from harmful radiation.
Yes indeed they are ionizing radiation. Of particular importance to astronauts who are exposed to much more than those who are Earth bound. But even flight crew on high flying aircraft have to pay attention to this.
Yes, alpha radiation is an ionizing radiation.
Yes, but there are a number of radiation besides ionizing radiation.
The importance of radiation is that it can get rid of cancer cells. It is highly useful in helping get rid of tumors.
It absorbs most of the sun's UV radiation.
Electromagnetic radiation is propogated as sine waves.
The important effect is that it induces DNA damage. This can be beneficial when treating cancer with radiation therapy, but radiation therapy is carcinogenic in itself.
Me too, I really need to know what exactly that is. Please someone answer that queation

Common types of radiation pyrometers include brightness, color, and total-radiation pyrometers. Of particular importance is the brightness pyrometer, which provides the highest accuracy of temperature measurements in the range from 103 to 104 °K.Total-radiation pyrometers can be used to measure temperatures beginning at 200°C.
It is the source of earth's magnetic field, which produces an extremely important shield against harmful solar radiation.

The square roots of frequency of x radiation is proportional to the atomic no of the element is called moseley's law.if u is frequency and z is atomic no
Ozone layer is the layer absorbing UV-B radiations. This UV radiation can cause skin cancer and DNA alteration. Thus, this is a layer which cannot be avoided.Ozone layer absorbs around 97% of the total radiation received from sun. Because it helps to block radiation earth is much cooler and habitable. Without ozone layer, humans would not have survived.
