The electromagnetic spectrum is the range of all frequencies of electromagnetic radiation which includes visible light as well as invisible radiations like radio waves, infrared rays, gamma rays. Mining crystals locked in the deep-sea could help fight climate change. A stochastic health risk is present at low exposure levels, where the likelihood of developing cancer increases with exposure. They are emitted by a decaying nucleus, that expels the gamma rays in an effort to become more stable as an atom. This is why they are useful in medicineto show whether bones are broken or where there is tooth decay, or to locate a tumor. However, great care must be taken, because gamma-rays can also damage the DNA of surrounding healthy tissue cells. These data can aid researchers in their search for geologically significant elements like sodium, magnesium, calcium, oxygen, silicon, iron, and titanium. Detecting gamma rays requires a special kind of detector, called a gamma rays telescope, which uses the Compton Scattering process to detect gamma rays. The wavelengths of gamma radiation are often less than a few tenths of an angstrom (10 10 meters), yet the energy of gamma photons exceeds tens of thousands of electron volts. (, 7. Gamma rays are identical in nature to other electromagnetic radiations such as light or microwaves but are of much higher energy. Other sources of gamma rays are alpha decay and gamma decay. Kinetic Friction Definition, Laws, Types, What is frictional force? Gamma rays are high frequency, extremely-short-wavelength electromagnetic waves with no mass and no charge. Maria is a teacher and a learning specialist and has master's degrees in literature and education. Both x-rays and gamma rays are forms of high-frequency (high-energy) ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. Uranium is a radionuclide that has an extremely long half-life. Gamma rays have a wavelength range below 100 pm and frequencies greater than 10 Hz. This helped me do my science homework :), This was extremely useful and informative ! Sometimes this can lead to cancer later on.
