The burn up of the absorbing isotopes is another limiting lifespan factor.

The primary decay products of isotopes of protactinium lighter than ( and including ) 231 Pa are actinium isotopes and the primary decay products for the heavier isotopes of protactinium a......

The fallout-fine white flaky dust of calcinated Bikini Island coral, which absorbed highly radioactive fission products and neutron activated isotopes-fell on the ship for three hours.

Large enough Planetesimals were heated by the decay of aluminium isotope. The most common decay mode of the isotopes with mass numbers lower than the three stable isotopes is inverse beta ......

Some rat brains took up a much larger dose of the aluminum isotope, suggesting wide individual variations in susceptibility.

It is the americium isotope used in an americium smoke detector based on an ionization chamber. Initial experiments yielded four americium isotopes : 241 Am, 242 Am, 239 Am and 238 Am. The......

In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas. In the universe, argon-36 is by far ......

"I think the argon isotope ratio measurement is very convincing, " said Dr . Kenneth A . Farley, a professor of geochemistry at the California Institute of Technology. Meanwhile, gases at ......

When the age-dating researchers bombard potassium-40 with neutrons, they can create an artificial isotope of argon called argon-39. Twenty-eight artificial isotopes of zirconium have been ......

Before dying, he confesses to experimenting with an artificial radioactive isotope, " serranium ", which he had bombarded with alpha particles for 200 hours ( 8 days and 8 hours ).

Astatine-218 was the first astatine isotope discovered in nature. Lighter astatine isotopes have quite magic number corresponding to a filled neutron shell. Its alpha decay half-life is in......

USEC's hope is a new technology, called Atomic Vapor Laser Isotope Separation, allows enrichment with one-tenth as much electricity. If atomic vapor laser isotope separation works and USEC......

Band isotope effect

Nuclear reactors produce mostly, among the berkelium isotopes, berkelium-249 . During the storage and before the fuel disposal, most of it beta decays to californium-249 . The latter has a......

The primordial nuclide beryllium-9, the only stable beryllium isotope, is an example of this type of nuclide. Still other possible beryllium isotopes have even more severe mismatches in ne......

Even though only one bismuth isotope is used ( bismuth-209 ), the reaction may occur in three possible ways, producing astatine-209, astatine-210, or astatine-211.

Nationally, he has served as President, Association of Radiation Oncologists of India, Member of the Scientific Advisory Board of the Indian Council of Medical Research, and Member of the ......

The boron isotope 10 B is responsible for the majority of the neutron absorption. He developed the use of boron isotopes for determining the pH of ancient oceans. Like all other elements, ......

The fourth chain has no such long lasting bottleneck isotope, so almost all of the isotopes in that chain have long since decayed down to very near the stability at the bottom.

Bulk isotope composition

The indium isotopes lighter than 115 In predominantly decay through electron capture or positron emission to form cadmium isotopes, while the other indium isotopes from 115 In and greater ......

Calcium isotope fractionation during mineral formation has led to several applications of calcium isotopes. Calcium isotope fractionation during mineral formation has led to several applic......

Californium-249 is formed from the beta decay of berkelium-249, and most other californium isotopes are made by subjecting berkelium to intense neutron radiation in a nuclear reactor.

Those carbon isotopes are part of what we have both looked for. Chemoautotrophic origin of the stable carbon isotope 13 C was confirmed experimentally. This was determined by comparing the......
