Radioactive Waste Management
The handling, treatment and disposal of hazardous radioactive waste which is usually a by-product of nuclear fission. However, other industries-not just nuclear power plants-can produce radioactive waste.
Radioactive Waste: Any waste that emits energy as rays, waves, or streams of energetic particles. Radioactive materials are often mixed with hazardous waste, usually from nuclear reactors, research institutions, or hospitals.
High-Level Radioactive Waste (HLRW)
Waste generated in core fuel of a nuclear reactor, found at nuclear reactors or by nuclear fuel reprocessing; is a serious threat to anyone who comes near the waste without shielding.
Low-Level Radioactive Waste: Wastes less hazardous than most of those associated with nuclear reactor; generated by hospitals, research laboratories, and certain industries.
Radioactive Substances: Substances that emit ionizing radiation.
Radioactive Waste: Any waste that emits energy as rays, waves, streams or energetic particles.
Radioactive Decay: Spontaneous change in an atom by emission of of charged particles and/or gamma rays; also known as radioactive disintegration and radioactivity.
Radioactive Substances: Substances that emit ionizing radiation.
radioactive - of or characterized by radioactivity.
radioactive waste - the byproduct of nuclear reactions that gives off (usually harmful) radiation.
radioactive fallout Airborne or deposited radioactive debris, including fission products, from a nuclear detonation.
radioactive material Any material which spontaneously emits particulate or electromagnetic ionizing radiation.
Radioactive: Having the property of releasing radiation.
Rain: Water falling to earth in drops that have been condensed from moisture in the atmosphere.
Radioactive Decay - The spontaneous breakdown of certain kinds of atomic nuclei into one or more nuclei of different elements, involving the release of energy and subatomic particles. [Crutzen, Paul J. and Graedel, T.E.
Radioactive Having the property of releasing radiation.
Raw sewage Untreated wastewater and its contents.
Raw water Intake water before any treatment or use.
R radioactive contamination
Definition (english only)
The contamination of any material, surface, environment or person by radioactive substances.
Radioactive fallout carried by the wind was later found in sheep in the UK, on clothing worn by people throughout Europe, and in rain in the United States.
A radioactive metallic element chemically similar to uranium. PM-10/PM-2.5 PM 10 is measure of particles in the atmosphere with a diameter of less than ten or equal to a nominal 10 micrometers. PM-2.5 is a measure of smaller particles in the air.
The radioactive dust particles that settle to earth after the denotation of a nuclear device. It is also used to describe dust particles settling from smoke, etc.
Feasibility study ...
Degraded radioactive materials, often referred to as "daughters" or "progeny"; radon decay products of most concern from a public health standpoint are polonium-214 and polonium-218.
Decontamination ...
Dose (for radioactive chemicals)
The radiation dose is the amount of energy from radiation that is actually absorbed by the body. This is not the same as measurements of the amount of radiation in the environment.
Half-life: Radioactively, half-life is the time required for half of a given quantity of material to decay. Chemically, it is the time required for half of a given quantity of material to undergo a chemical reaction.
A disposal site for radioactive waste materials that uses earth or water as a shield.

Some of these categories are solids, sulfur compounds, volatile organic chemicals, particulate matter, nitrogen compounds, oxygen compounds, halogen compounds, radioactive compounds and odors.
New York State Energy Research and Development Authority (NYSERDA) The New York State Energy Research and Development Authority coordinates energy matters and monitors low-level radioactive waste generation and management for the State.
Radionuclides are radioactive elements that are naturally present in rocks and soil but they also may be man-made.
transient tracers Chemical elements (often radioactive) or compounds that have finite lifetimes. Atmospheric testing of nuclear weapons from the mid-1950s to the early 1960s released large quantities of radionuclides to the atmosphere.
Naturally-Occurring Radioactive Material (NORM): An acronym for Naturally Occurring Radioactive Material. Naturally occurring radioactive materials are common in virtually all rocks, minerals, and soils.
RADIOCARBON DATING Carbon-14 is a radioactive isotope of carbon, which is present in minute quantities in the atmosphere. Living things such as wood and the bones of living animals absorb this carbon naturally.
Disposal- Final placement or destruction of toxic, radioactive, or other wastes; surplus or banned pesticides or other chemicals; polluted soils; and drums containing hazardous materials from removal actions or accidental releases.
Concerns about radioactive fuels getting into terrorist hands.
Solar: still fairly expensive. Does not work at night or on cloudy days.
Wind: best locations are far from where the power is needed. Sporadic.
Tides ...
Short-lived radioactive decay products of radon that decay into longer-lived lead isotopes. The daughter isotopes can attach themselves to airborne dust and other particles and, if inhaled, damage the lining of the lung.
Uranium: A heavy, naturally radioactive, metallic element that is used to produce nuclear power.

Waste-to-energy: The process of burning solid waste, landfill gas, tires, or other forms of waste to produce heat or electricity.
Means by which something may be followed; for example a radioactive isotope may replace a stable chemical element in a toxic compound enabling the toxicokinetics to be followed.
Radon: colorless, odorless, tasteless, radioactive gas.
Receiving Waters : bodies of water that receive runoff or wastewater discharges, such as rivers, streams, lakes, estuaries, and ground water.
Radon: A colorless, naturally occurring, radioactive, inert gaseous element formed by radioactive decay of radium atoms in soil or rocks.
Contaminant: Any physical, chemical, biological, or radioactive substance that can adversely affect air, water or soil.
Half-Life is the time required for a pollutant to lose one-half of its original concentration, or the time required for half of the atoms of a radioactive element to decay or the time required for the elimination of half a total dose from the ...
The half-life of Radium is 1,580 years. 2. The time required for half of the atoms of a radioactive element to undergo self-transmutation or decay. 3. The time required for elimination of one-half a total dose from the body.
Hazardous / special waste includes a wide range of rubbish, including things like asbestos, fridges, solvents, and radioactive waste. Businesses who need to dispose of hazardous waste must do so through a registered company, see also Duty of Care.
geothermal energy: electricity produced by using geothermal heat (that is, heat found underground) to create steam to drive turbines. Geothermal heat originated in various ways, including the original formation of the planet, or radioactive decay ...
either electrically-charged particles or heat, which is then harnessed to produce electricity. This technology is currently being researched but thus far is not cost-effective. Some scientists believe that it is possible to produce non-radioactive ...
Photorespiration, growth respiration and maintenance respiration are responsible for carbon outputs or withdraws. We can actually track where carbon molecules go after they enter a tree. Here radioactive carbon is being applied to a leaf.
out over tens -- perhaps hundreds -- of years, discounting is used to help evaluate the value of measures that deal with problems such as stratospheric ozone depletion, global climate change, and the disposal of low- and high-level radioactive wastes.
Air pollutants are often grouped in categories for ease in classification. Some of these categories are solids, sulfur compounds, volatile organic compounds, particulate matter, nitrogen compounds, oxygen compounds, halogen compounds, radioactive ...
Thermal springs owe their heat content to the natural geothermal heat created by the hot core of the earth and the decay of radioactive minerals in the lithosphere and to underground magma chambers in volcanic regions.
