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 ).

Radioactive patent medicines mostly disappeared, but other applications of radioactive materials persisted, such as the use of radium salts to produce glowing dials on meters.

Radioactive wastes are wastes that contain radioactive material.

A summary of the amounts of radioactive wastes and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency ( IAEA ) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

* 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 ).

* Radioactive displacement law of Fajans and Soddy, elements / isotopes created during radioactive decay

Additionally, the site is the location of the Area 5 Radioactive Waste Management Complex, which sorts and stores low-level radioactive waste that is not transuranic and has a half life not longer than 20 years.

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

Radioactive waste treatment is the treatment and containment of radioactive waste.

* Activity ( radioactivity ), radioactive decay # Radioactive decay rates, the number of radioactive decays per second

* Radioactive springs contain traces of radioactive substances such as radium or uranium.

* Radioactive waste treatment – the treatment and containment of radioactive waste.

Radioactive quackery refers to various products sold during the early 20th century containing radioactive ingredients, after the discovery in 1896 of radioactive decay.

* Many brands of toothpaste were laced with radioactive substances that was claimed to make teeth shine whiter, such as Doramad Radioactive Toothpaste.

Radioactive isotopes at or above mass number 93 decay by β < sup >−</ sup >, whereas those at or below 89 decay by β < sup >+</ sup >.

Radioactive beams of specific isotopes are widely used in the fields of experimental physics, biology and materials science.

* Radioactive isotopes have the advantages of being detectable in very low quantities, in being easily measured by scintillation counting or other radiochemical methods, and in being localizable to particular regions of a cell, and quantifiable by autoradiography.

Radioactive isotopes must capture another neutron faster than they can undergo beta decay in order to create abundance peaks at germanium, xenon, and platinum.

Radioactive tracer isotopes are injected with hydraulic fracturing fluid to determine the injection profile and location of fractures created by hydraulic fracturing.

Radioactive isotopes from ISAC are sent to TITAN to undergo cooling, charge-breeding and trapping.

Radioactive isotopes of uranium, thorium and potassium are the primary contributors to this decay heat, and this Radioactive decay is the primary source of heat from which Geothermal energy derives.

Radioactive tracer isotopes are injected with hydraulic fracturing fluid to determine the injection profile and location of fractures created by hydraulic fracturing.

RIBO stands for the Radioactive Ion Beam Optimization, a concept closely linked to the extraction of rare isotopes from targets.

Radioactive krypton-81 is the product of reactions with cosmic rays that strike the atmosphere, along with some of the other isotopes of krypton.

Radioactive isotopes of phosphorus include:

An analysis of the isotopes produced, performed at the National Institute of Radioactive Elements in Belgium has shown that the Mo-99 samples produced at ARGUS are characterized by an extreme radiochemical purity, i. e. the impurity content in them is lower than the allowable limits by 2 – 4 orders of magnitude.

Radioactive indium-111 ( in very small amounts on a chemical basis ) is used in nuclear medicine tests, as a radiotracer to follow the movement of labeled proteins and white blood cells in the body.

: Radioactive or toxic chemical sites associated with its former defense industries and test ranges are found throughout the country and pose health risks for humans and animals ; industrial pollution is severe in some cities ; because the two main rivers which flowed into the Aral Sea have been diverted for irrigation, it is drying up and leaving behind a harmful layer of chemical pesticides and natural salts ; these substances are then picked up by the wind and blown into noxious dust storms ; pollution in the Caspian Sea ; soil pollution from overuse of agricultural chemicals and salination from poor infrastructure and wasteful irrigation practices

Radioactive chemical tracers emitting gamma rays or positrons can provide diagnostic information about a person's internal anatomy and the functioning of specific organs.

The book was a source of inspiration to David Hahn, nicknamed " the Radioactive Boy Scout " by the media, who tried to collect a sample of every chemical element and also built a model nuclear reactor, which led to the involvement of the authorities.

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 elements are used for radiometric dating, the primary method for establishing an absolute time scale in geochronology.

Fowler: Radioactive elements of a low atomic number, Ph. D. dissertation

Radioactive decay from other elements is the source of most of the helium-4 found on Earth, produced after the planet cooled and solidified.

* CBRNE ( Chemical, Biological, Radioactive, Nuclear & Explosive )-Specially-trained Toronto EMS paramedics operate together with elements of the Toronto Police Service and Toronto Fire Services to provide a joint-service Terrorism / Hazardous Materials Response team.

* Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment.

Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine.

The first such instance occurred in the seventh season episode " Radioactive Man ", in which Comic Book Guy is logging on to his favorite newsgroup alt. nerd. obsessive.

Radioactive tracers form the basis of a variety of imaging systems, such as PET scans, SPECT scans and Technetium scans.

Morley Erwin maintained the Iron Man armor and served as Rhodes ’ technical support while Rhodes fought villains such as the Mandarin, Thunderball, the Zodiac, and the Radioactive Man as Iron Man.

Radioactive decay could also provide the energy necessary for such activity, as cryovolcanoes can emit water mixed with ammonia, which would melt at-95 ° C and create an extremely cold liquid that would flow out of the volcano.

The character ’ s popularity also led to parodies of Boris himself and “ revenge ” stories appearing in titles such as Blackthorne Publishing ’ s Laffin ’ Gas and Eclipse Comics ’ Adolescent Radioactive Black Belt Hamsters.
