short-lived radioisotope

This energy could have come from accretion, short-lived radioisotopes, and core formation.

Many of the fission products are either non-radioactive or only short-lived radioisotopes.

For the test, the subject drinks a solution of glucose labeled with a short-lived radioisotope, carbon-13.

The decay of the short-lived radioisotopes created in fission continues at high power, for a time after shut down.

The primary fallout hazard is gamma radiation from short-lived radioisotopes, which represent the bulk of activity.

The focus of this shortage is a short-lived radioisotope that most patients have probably never heard of -- technetium-99m, the "m" standing for metastable.

• releases consisting mainly of noble gases (ie., short-lived radioisotopes)

The gamma rays were emitted by a pellet of the short-lived radioisotope Lanthanum-140 positioned in the center of the sphere.

Iodine-131 is a short-lived radioisotope that has a radioactive decay half-life of about eight days, the IAEA said.

In most cases, these short-lived radioisotopes decay to stable elements within minutes, hours, or days, allowing patients to be released from the hospital in a relatively short time.

For most of the ships, reboarding had to wait until the short-lived radioisotopes decayed; ten days elapsed before the last of the targets could be boarded.

The releases from nuclear reactor accidents and bomb detonations will contain a greater amount of the short-lived radioisotopes (when the amounts are expressed in activity Bq)).

MDS Nordion's new cyclotron will meet the current demand for the critical, short-lived radioisotopes that are used in a wide range of diagnostic and therapeutic medical applications.

The experiment used significant amounts of a short-lived radioisotope lanthanum-140, a potent source of gamma radiation; the RaLa is a contraction of Radioactive Lanthanum.

To study the behavior of converging shock waves, Robert Serber devised the RaLa Experiment, which used the short-lived radioisotope lanthanum-140, a potent source of gamma radiation.

Nuclear Medicine Radiographers use gamma rays produced from short-lived radioisotopes that emit radioactive tracers to investigate trauma and disease such as cancer, heart disease and brain disorders.

In 1935 they were awarded the Nobel Prize in Chemistry for their discovery of "artificial radioactivity," resulting from the creation of short-lived radioisotopes from the bombardment of stable nuclides such as boron, magnesium, and aluminum with alpha particles.

The source of the heat was most likely energy coming from the decay of short-lived radioisotopes (half-lives less than a few million years) that were present in the newly formed solar system, especially Al and Fe, although heating may have been caused by impacts onto the asteroids as well.

Some early evidence for nuclear fission was the formation of a short-lived radioisotope of barium which was isolated from neutron irradiated uranium (Ba, with a half-life of 83 minutes and Ba, with a half-life of 12.8 days, are major fission products of uranium).

Because the twin reactors, PLUTO and DIDO, worked on a continuous basis rotating in and out of operation, there was continued flow of short-lived radioisotopes for hospitals.The radioisotopes generated account for 70% of the UK radioisotopes sold on the international markets.
