: 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

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

The voice and humor of Queer Duck character Bi-Polar Bear – voiced by Ren & Stimpy and Futurama actor Billy West – is also done in the style of Paul Lynde, as was the supervillain The Scoutmaster in the Simpsons episode Radioactive Man.

In " Radioactive Man " ( 1995 ), he is depicted as having been one of the original Little Rascals.

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

Radioactive Man # 679 ( September 1994 ), written by Steve Vance, is entitled " Who Washes the Washmen's Infinite Secrets of Legendary Crossover Knight Wars?

The municipality is mainly known for the Borssele Nuclear Power Station and the Central Storage For Radioactive Waste.

Radioactive Iodine-131 is used in patients with papillary or follicular thyroid cancer for ablation of residual thyroid tissue after surgery and for the treatment of thyroid cancer.

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 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 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.

The Commission produced a series of books including Radioactive Heaven and Earth, Plutonium: The Deadly Gold of the Nuclear Age, and Nuclear Wastelands, a comprehensive study of the health and environmental impact of the global nuclear weapons production complex.

Despite being panned by critics, The Firm's two albums, The Firm and Mean Business, achieved moderate sales success and produced the radio hits " Radioactive ", " Satisfaction Guaranteed ", and, in the UK, " All The King's Horses ".

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

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 gasses were released into the atmosphere.

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 sodium-24 may be formed by neutron activation during operation, posing a slight radiation hazard ; the radioactivity stops within a few days after removal from the reactor.

# The Radioactive Camel Affair by Peter Leslie.

* The Crisis, along with other crossovers and " event " comics, was parodied by Simpsons Comics in the Radioactive Man series.

The event became a short-lived media sensation, and a book by Ken Silverstein called The Radioactive Boy Scout was written about the incident and published in 2004.

Following the layoff of 800 employees on March 31, 2009, the consortium had about 100 employees remaining on the project prior to all being laid off by the end of the 2010 financial year due to zero funding in the 2011 budget for the Office of Civilian Radioactive Waste Management.

On February 17, 2006, the Department of Energy ’ s Office of Civilian Radioactive Waste Management ( OCRWM ) released a report confirming the technical soundness of infiltration modeling work performed by U. S. Geological Survey ( USGS ) employees.

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

* 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 contamination was controlled in the emergency response center by city-officials.

* Radioactive heat generated by cooled masses of granite

Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production.

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