Gamma radiation, the most powerful type of ionizing radiation, is released in high quantities during events such the detonation of a nuclear weapon. Though exposure to non-ionizing radiation is relatively much safer, side effects from short-term exposure can still cause health problems. The ...
Are all gamma rays shorter than x-rays? What type of radiation does the sun produce? What are alpha, beta and gamma decay? What produces electromagnetic radiation? What is Lyman-alpha radiation? What type of ionizing radiation is emitted by fluoroscopy?
What is positron decay stopped by? When polonium-210 decays by alpha radiation, what isotope is formed? What is emitted from the nucleus during beta decay? What is the alpha decay of iridium-174? How radioactive is nihonium? What makes a radioactive decay chain end?
A gamma counter is a device that measures the gamma radiation in a sample. The main situations in which a person would use a gamma...
Matter—the visible kind, that is—interacts with the universe in many ways. It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating...
Nuclear fusion occurs when extreme pressure forces the protons in the nucleus of one element to combine or fuse into another, heavier element. Using the ever famous E=mc2, the resulting difference in mass is converted to energy. Some of that released energy is emitted as gamma rays. The fusi...
Radiation therapy uses x-rays or gamma rays to treat cancer. Radiation kills cancer cells and may stop the cancer from spreading. It may be given with radioactive iodine therapy or after surgery to remove your thyroid. Medicine may be given to help bring your thyroid hormone level back to ...
In 2014, NASA'sFermi Gamma-ray Space Telescopemade maps of the heart of our galaxy, theMilky Way, in gamma-ray light, revealing an excess of gamma-ray emissions extending from its core. "The signal we found cannot be explained by currently proposed alternatives and is in close agreement wi...
This emitted energy is equal to the difference between the high and low energy levels, and may be seen as light depending on its wave frequency, discussed below. The wave form of light is actually a form of energy that is created by an oscillating charge. This charge consists of an ...
Theelectromagnetic radiationof an object is stretched out slightlyinside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, orredsh...
