Nuclear Radiation Wikipedia

Cherenkov saw a faint bluish light around a radioactive preparation in water during experiments.

Bohemian grove secret society. Natural sources include the sun lightning and supernova explosions. Intense thermal radiation at the hypocenter forms a nuclear fireball which if the explosion is low enough in altitude is often associated with a mushroom cloud. Ntv bbc hisashi ouchi masato shinohara and yutaka yokokawa were preparing a small batch of fuel the first in three years for the joyo experimental fast breeder reactor.

Radioactive decay also known as nuclear decay radioactivity radioactive disintegration or nuclear disintegration is the process by which an unstable atomic nucleus loses energy by radiationa material containing unstable nuclei is considered radioactivethree of the most common types of decay are alpha decay beta decay and gamma decay all of which involve emitting one or more particles. These include both cosmic radiation and environmental radioactivity from naturally occurring radioactive materials such. Both alpha and beta particles have an electric charge and mass and thus are quite likely to interact with other atoms in their path.

Upon adding the tank reached a critical stage and went into a self sustaining nuclear fission chain reaction releasing intense gamma and neutron radiation. Artificial sources include nuclear reactors particle accelerators and x ray tubes. Background radiation originates from a variety of sources both natural and artificial.

Ionizing radiation is generated through nuclear reactions nuclear decay by very high temperature or via acceleration of charged particles in electromagnetic fields. Gamma g radiation consists of photons with a wavelength less than 3x10 11 meters greater than 10 19 hz and 414 kev. Gamma radiation emission is a nuclear process that occurs to rid an unstable nucleus of excess energy after most nuclear reactions.

The radiation is named after the soviet scientist pavel cherenkov the 1958 nobel prize winner who was the first to detect it experimentally under the supervision of sergey vavilov at the lebedev institute in 1934. Nuclear medicine and medical physics. Medical physics is an important field of nuclear medicine.

Examples include lethal effects to individuals radioactive isotope to the environment or reactor core melt the prime example of a major nuclear accident is one in which a reactor core is damaged and. Its sub fields include nuclear medicine radiation therapy health physics and diagnostic imaging. Highly specialized and intricately operating equipment including x ray machines mri and pet scanners and many other devices provide most of modern medicines diagnostic capabilityalong with.

Background radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources. A nuclear weapon also called an atom bomb nuke atomic bomb nuclear warhead a bomb or nuclear bomb is an explosive device that derives its destructive force from nuclear reactions either fission fission bomb or from a combination of fission and fusion reactions thermonuclear bombboth bomb types release large quantities of energy from relatively small amounts of matter.
