For example, uranium-238 is weakly radioactive, but pitchblende, a uranium ore, is 13 times more radioactive than the pure uranium metal because of the radium and other daughter isotopes it contains. Not only are unstable radium isotopes significant radioactivity emitters, but as the next stage in the decay chain they also generate radon , a heavy, inert, naturally occurring radioactive gas.

See what you already know about the radioactive isotope with this interactive quiz and practice trivia.

Notable isotopes. Plutonium-238 has a half-life of 87.74 years and emits alpha particles.Pure 238 Pu for radioisotope thermoelectric generators that power some spacecraft is produced by neutron capture on neptunium-237 but plutonium from spent nuclear fuel can contain as much as a few percent 238 Pu, originating from 237 Np, alpha decay of 242 Cm, or (n,2n) reactions. Using this printable worksheet and interactive quiz, you can test what you know about tracking biological molecules with radioactive isotopes. You The Technical Details: Radioactive Decay Beta Decay. Because 14 C is radioactive, it decays over time–in other words, older artifacts have less 14 C than younger ones.

Start studying Isotopes and Radioisotopes. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Isotopes utilized in nuclear medicine fall into two broad categories: Stable and Unstable. Stable isotopes do not undergo radioactive decay. radioactive decay.

Radioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter). The rate of decay is conveniently expressed in terms of an isotope's half-life, or the time it takes for one-half of a particular radioactive isotope in a sample to decay.

This table contains the elements that have no stable isotopes. Each element is followed by the most stable known isotope and its half-life .

Radioactive isotopes are used to form images of the thyroid, bones, heart, liver, and many other organs. They used also have helped in treating diseased organs and tumors. The most commonly used example of such isotopes is technetium-99, which accounts for 80% of nuclear medicine procedures.

Their nuclei are unstable, so they break down, or decay, and emit radiation. Q: What makes the nucleus of a radioisotope … 2015-08-20 The unstable (radioactive) isotopes are either primordial or postprimordial. Primordial isotopes were a product of stellar nucleosynthesis or another type of nucleosynthesis such as cosmic ray spallation, and have persisted down to the present because their rate of decay is … 2008-05-12 2012-02-23 About This Quiz & Worksheet Radioactive isotopes have a myriad of conventional, everyday uses.
