Radioactive waste typically comprises a number of radioisotopes: unstable configurations of elements that decay, emitting ionizing radiation which can be harmful to humans and the environment.

* Radioactive decay leading to specific radiogenic daughter nuclides.

* Radioactive decay leading to spontaneous fission.

Radioactive decay accounts for about of the Earth's internal heat, powering the geodynamo and plate tectonics.

Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting ionizing particles and radiation.

* Radioactive decay, the set of various processes by which unstable atomic nuclei ( nuclides ) emit subatomic particles

* Radioactive decay

Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles ( ionizing radiation ).

Radioactive decay is a stochastic ( i. e., random ) process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay.

Radioactive decay of the fuel produces heat which flows through the thermocouples to the heat sink, generating electricity in the process.

* Radioactive decay for the mathematics of chains of exponential processes with differing constants

* Radioactive decay, the amount of radioactive material in which one nucleus decays per second, measured in Becquerels

This is often the subject of parody, for example in the Simpsons episode " Radioactive Man " where the onomatopoeic words are replaced with snuh !, newt!

Radioactive potassium-40 is common in micas, feldspars, and hornblendes, though the closure temperature is fairly low in these materials, about 125 ° C ( mica ) to 450 ° C ( hornblende ).

* Radioactive waste ( some home smoke detectors are classified as radioactive waste because they contain very small amounts of a radioactive isotope of americium-see: Disposing of Smoke Detectors ).

Other facilities in TA-III include a paper destructor, the Melting and Solidification Laboratory and the Radioactive and Mixed Waste Management Facility ( RMWMF ).

Radioactive labels do not require enzyme substrates, but rather allow the placement of medical X-ray film directly against the western blot which develops as it is exposed to the label and creates dark regions which correspond to the protein bands of interest ( see image to the right ).

* Libby, W. F. " Radioactive Fallout " United States Department of Energy ( through predecessor agency the Atomic Energy Commission ), ( May 29, 1958 ).

* Pat Conway, later Sheriff Clay Hollister on western series Tombstone Territory, appears as Mel in " Radioactive " ( 1955 ).

The next version, organized by the robot Ultron under the alias of Crimson Cowl, consisted of Klaw, Melter, Radioactive Man, Whirlwind, and the second Black Knight ( who joined with the intention of betraying the Masters ).

They include Aftershock ( the daughter of Electro ), Warhead ( the son of Radioactive Man ), Mortar ( the daughter of Grey Gargoyle ), Singularity ( the son of Graviton ) and Ember ( the son of Pyro ).

Jim Avignon is a prolific, provocative and highly original artist who has published a number of books including: " Popbones " ( 1996 ), " Busy " ( with DAG, 1998 ) and " Non Radioactive " ( with Lisa Brown, 2000 ).

Colby Colb started as an intern at the station and following the success of Radioactive went on to host nights ( 6pm – 10pm ), Mornings with Wendy Williams and Dee Lee ( The Dream Team ).

Parents are often concerned that orthodontic appliances may cause teeth to decay.

Starting in the 1970s, the Bronx often symbolized violence, decay, and urban ruin.

Other rates of excited state decay are caused by mechanisms other than photon emission and are, therefore, often called " non-radiative rates ", which can include:

The extremely strong bond in elemental nitrogen dominates nitrogen chemistry, causing difficulty for both organisms and industry in breaking the bond to convert the into useful compounds, but at the same time causing release of large amounts of often useful energy when the compounds burn, explode, or decay back into nitrogen gas.

PGNAA is characterised by short irradiation times and short decay times, often in the order of seconds and minutes.

DGNAA is characterised by long irradiation times and long decay times, often in the order of hours, weeks or longer.

In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts ( lighter nuclei ), often producing free neutrons and photons ( in the form of gamma rays ), and releasing a very large amount of energy, even by the energetic standards of radioactive decay.

Social conservatives often see the West as a decadent and nihilistic civilization which has abandoned its roots in Christianity and / or Greek philosophy, leaving it doomed to fall into moral and political decay.

Radiometric dating ( often called radioactive dating ) is a technique used to date materials such as rocks, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Authors doubting that decay causes forgetting from short-term memory often offer as an alternative some form of interference: When several elements ( such as digits, words, or pictures ) are held in short-term memory simultaneously, their representations compete with each other for recall, or degrade each other.

It often contains radium and its decay products.

During the 1970s and 1980s, urban decay was often associated with central areas of cities in North America and Europe.

This process happens when an energetic particle from a radioactive decay, often an alpha particle, reacts with a nucleus of another atom to change the nucleus into another nuclide.

The necromancer might also surround himself with morbid aspects of death, which often included wearing the deceased's clothing and consuming foods that symbolized lifelessness and decay such as unleavened black bread and unfermented grape juice.

This is largely due to the fact that volcanic rocks are often rich in potassium bearing minerals such as Orthoclase and decay easily.

In the 1970s, for instance, his standard set-up involved two independently controlled amplifiers to give a stereo effect onstage, and he often would use the swell pedal to counteract the " normal " attack and decay of notes.

Urban decay, and urban prairie are common in the formerly industrialized and once heavily populated East St. Louis ; other cities in St. Clair County often border agricultural or vacant lands.

A dark stain is often present at the rear of the organism, probably representing decay fluids.

Antiquaries often appeared to possess an unwholesome interest in death, decay, and the unfashionable ; while their focus on obscure and arcane details meant that they seemed to lack an awareness both of the realities and practicalities of modern life, and of the wider currents of history.

Collisions between molecules often leave them in excited states which can emit radiation as those states decay.

Although the term " skin effect " is most often associated with applications involving transmission of electrical currents, the skin depth also describes the exponential decay of the electric and magnetic fields, as well as the density of induced currents, inside a bulk material when a plane wave impinges on it at normal incidence.
