Replies: Cosmic rays are charged nuclear fragments, usually protons, traveling at almost the speed of light.

The steel armor effectively blocked all the protons, neutrons, nuclear fragments, mesons and other flotsam produced by the collision cascade, passing only the neutrinos.

The pattern of radiation and nuclear fragments from the decaying atom matched the pattern predicted by theory for the decay of Element 114, the scientists said.

Necrotic cells release nuclear fragments as potential autoantigens, as well as internal danger signals, inducing maturation of dendritic cells (DCs), since they have lost their membranes' integrity.

As they undergo fission, they break into nuclear fragments, nuclei of lighter elements, and emit various combinations of electrons, neutrons, helium nuclei (called alpha particles) and gamma rays.

Surgical causes of endothelial failure include both acute intraoperative trauma as well as chronic postoperative trauma, such as from a malpositioned intraocular lens or retained nuclear fragment in the anterior chamber.

But in the somewhat weaker gravity at the surface of the star, scientists theorize, nuclear fragments with positively charged protons might survive and combine with neutrons to create forms of matter inconceivable in a terrestrial environment.

By operating fast ionization chambers within a cloud chamber, Herbert Bridge showed that the bursts of ionization they recorded were primarily produced by relatively low energy cosmic rays, whose nuclear interactions typically involve the ejection of several heavily ionizing nuclear fragments.

We restricted our flow cytometric analysis to the determination of DNA ploidy because increased amounts of nuclear fragments after enzymatic digestion reduce the accuracy of cell cycle analysis accounting for the relatively poor correlation between proliferative activity in unfixed compared with paraffin embedded material.

Ken Mellendorf Math, Science, Engineering Illinois Central College A radioactive substance is one that EMITS some sort of "elementary" particle (electron, proton, neutron, or an atomic nuclear fragment such as an alpha particle), or some high energy electromagnetic radiation (X-rays, gamma rays, etc.).
