		Most radioisotopes are made by bombarding a stable element with neutrons in the core of a nuclear reactor (see fission).
		The radiations given off by radioisotopes are easy to detect (hence their use as tracers), can in some instances penetrate substantial thicknesses of materials, and have profound effects (such as genetic mutation) on living matter.
		Radioisotopes have many uses in medicine, for example in radiotherapy and radioisotope scanning.

		A Synthetic radioisotope is a radionuclide that is not found in nature: no natural process or mechanism exists which produces it, or it is so unstable that it decays away in a very short period of time.
		A radioisotopes is an atom with an unstable nucleus.
		Radioisotopes do occur naturally, but are also artificially produced by bombarding particular elements elements with neutrons (usually emitted from a nuclear reactor).

		Synthetic isotopes are not naturally occurring on Earth, but they can be created by nuclear reactions.
		Radioisotope ages that are significantly greater (or less) than conformable with geological assignment are reasonably explainable on the basis of postulated parent loss and/or daughter gain (or parent gain and/or daughter loss), as a result of solution penetration and/or heating in one or more episodes since the initial formation of the mineral.
		When the physical measurement of a radioisotope half-life (disintegration rate) has a large range of uncertainty, it is only reasonable for geochronologists to use the boundary value that produces radioisotope ages most closely in accord with expectations based on geologic criteria.

	Radioactive isotope : Radioisotope
		Radioisotopes are unstable radioactive isotopes that either occur naturally or are produced by bombarding small amounts of particular elements with neutrons (usually emitted from a nuclear reactor).
		Environmentally, radioisotopes are used to trace and analyse pollutants, to study the movement of surface water, and to measure water runoffs from rain and snow, as well as the flow rates of streams and rivers.
		Trace radioisotopes are those that occur in minute amounts in nature either due to inherent rarity or to half-lifes that are significantly shorter than the age of the earth.

	Synthetic radioisotope - Wikipedia, the free encyclopedia
		Some synthetic radioisotope are extracted from spent nuclear reactor fuel rods, which contain various fission products.
		For example, it is estimated that up to 1994, about 49,000 TBq (78 metric ton) of technetium was produced in nuclear reactors, which is by far the dominant source of terrestrial technetium.
		Other synthetic isotopes are produced in significant quantities by fission but are not yet being reclaimed.

		Synthetic nuclide work on ship must be undertaken only in designated radioisotope laboratory vans that should be able to contain spills of radioisotopes under adverse weather conditions.
		If natural abundance radioisotope work is to be done on a voyage then the CTD room is to be designated as a 'clean room' for that voyage, with restricted access to personnel and clothing changes required on entry etc.
		Therefore natural abundance radioisotope work is to be done at a station in a designated 'clean-room' container laboratory, with restricted access to personnel and clothing changes required on entry etc. Synthetic nuclide work is to be done as per existing procedures in the designated laboratories at each base.

	Mars Exploration Rover Mission: Technology
		Each radioisotope heater unit produces about one watt of heat and contains about 2.7 grams (0.1 ounce) of plutonium dioxide as a pellet about the size and shape of the eraser on a standard pencil.
		This design of multiple protective layers had been tested extensively, and the heater units are expected to contain their plutonium dioxide under a wide range of launch and orbital-reentry accident conditions.
		The batwings are made of silicon-coated Vectran, the same synthetic material out of which the airbags were fashioned.

	Platinum auction - an AuKT.net auctions page
		Naturally occurring platinum is composed of five stable isotopes and one radioisotope, Pt-190, which has a very long half-life (over 6 billion years).
		There are also many other radioisotopes with the most stable being Pt-193 with a half-life of 50 years.
		This metal doesn't normally cause health problems due to its unreactive nature but all compounds of platinum should be considered to be highly toxic.

	SRI International's Biosciences Division provides radioisotope and stable isotope labeling services
		Whether one is interested in radioisotopes or stable isotopes, only a limited number and variety of isotopically enriched intermediates are readily available.
		The intermediates used in the synthesis route for your desired target compound may not exist as labeled compounds; thus, a whole new synthesis will be needed for incorporation of the isotope of interest.
