What does A stand for?

It cant be used in weapons or reactors, but as the atoms decay, they emit alpha particles, or helium nuclei, that easily convert their energy to heat.

Occasionally, they are the result of electrical charges from either neutrons from cosmic rays or alpha particles emitted by the breakdown of radioactive materials.

These progeny emit alpha particles (sub-atomic particles with mass and energy), which can strike lung cells and cause physical and/or chemical damage to DNA.

He explores the interactions with matter and energetic particles, including photons, electrons, protons, alpha particles and neutrons with a variety of applications including photon and neutron cross sections, charged particle stopping powers, electron mean ranges and angular distributions, covering photons as they appear in long wavelengths and other configurations and as an element of photoelectric absorption, electrons, including in elastic scattering from and atom and in the case of collision energy loss, protons and heavier ions, including proton and alpha particle stopping powers in selected materials, and a range of topics on neutron interactions.

In an upcoming Physical Review Letters, Taleyarkhan's team presents evidence of fusion in bubbles initiated by a uranium-based trigger that emits alpha particles instead of neutrons.

He energized the national and international fusion communities to focus their attention on stability and transport issues associated with fast particles, and to develop techniques to observe alpha particle related phenomena in present experiments.

The small sizes of the bone and marrow cavities and the short ranges of the alpha particles complicate accurate dose estimates to the red bone marrow and bone endosteum.
