cosmogenic

The two most frequently measured cosmogenic nuclides are beryllium-10 and aluminum-26.

Its stated mission is conducting original research in cosmogenic isotopes.

These are cosmogenic isotopes, produced from interaction with cosmic rays.

These cosmogenic nuclides eventually reach the Earth's surface and can be incorporated into living organisms.

Cosmogenic Aluminium-26 was first applied in studies of the Moon and meteorites.

The site has been dated to 4.2 1.9 thousand years ago based on the cosmogenic C terrestrial age of the meteorite.

The most common of these dating techniques is Cosmogenic radionuclide dating.

Cosmogenic nuclides such as these are produced by chains of spallation reactions.

Wells used a method based on cosmogenic helium-3, which forms by cosmic ray bombardment at the ground surface.

Cosmogenic dating suggests that basal sediment entered the cave some 2 million years ago.

There are both radioactive and stable cosmogenic isotopes.

Cosmogenic nuclides may be either stable or radioactive.

Since the cosmic ray spallation route is the only possible source of beryllium-7 and beryllium-10 occurrence naturally in the environment, they are therefore cosmogenic.

The deep underground location reduces unwanted cosmogenic signals ("background") and allows a more sensitive dark matter search.

To measure cosmogenic isotopes produced within solid earth materials, such as rock, samples are generally first put through a process of mechanical separation.

Empedocles' philosophy is best known for being the origin of the cosmogenic theory of the four classical elements.

These are known as "cosmogenic radionuclides."

By measuring cosmogenic isotopes, scientists are able to gain insight into a range of geological and astronomical processes.

Sediment isotope analysis of cosmogenic atoms in the fossil yielded an age of about 7 million years.

The latter, if non-primordial, are called cosmogenic nuclides.

These equations can be combined to give the total concentration of cosmogenic radionuclides in a sample as a function of age.

Cosmogenic production of C, Be and Cl show changes tied to solar activity.

The function of these accelerators is to measure scarce, (cosmogenic) isotopes such as aluminium-26, beryllium-10, iodine-129 and the aforementioned carbon-14.
