regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue...
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4...- recoil nucleus than by the alpha particle itself. In 1931, Failla and Henshaw reported on determination of the relative biological effectiveness (RBE) of...
- Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or "decays"...
Lipoprotein (redirect from Plasma lipoprotein particle)VLDL particles bump with HDL particles; as a result, HDL particles donate apolipoprotein C-II and apolipoprotein E to the nascent VLDL particle. Once...- Radiobiology (redirect from Biological effects of ionizing radiation)relative biological effectiveness of alpha radiation to cause biological damage after alpha-emitting radioisotopes enter living cells. Ingested alpha emitter...
Radiation (section Alpha radiation)ultraviolet, x-rays, and gamma radiation (γ) particle radiation consists of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β),...- Ionizing radiation (category Radiation health effects)33 eV.[citation needed] Typical ionizing subatomic particles include alpha particles, beta particles, and neutrons. These are typically created by radioactive...
Linear energy transfer (category Radiation effects)the Relative Biological Effectiveness of the alpha particle in the cytoplasm, while ignoring the recoil nucleus contribution, which alpha-parent being...

radiation from pitchblende was differentiated into alpha rays (alpha particles) and beta rays (beta particles) by Ernest Rutherford through simple experimentation...
Gamma ray (redirect from Gamma particle)another property making them unlike alpha and beta rays. Gamma rays were first thought to be particles with mass, like alpha and beta rays. Rutherford initially...
Alpha-synuclein (aSyn) is a protein that, in humans, is encoded by the SNCA gene. Alpha-synuclein is a neuronal protein that regulates synaptic vesicle...- Drude particles are model oscillators used to simulate the effects of electronic polarizability in the context of a classical molecular mechanics force...
Radiation burn (redirect from Alpha burn)as beta particles are not able to penetrate deeply into a body; these burns can be similar to sunburn. Alpha particles can cause internal alpha burns if...
Radioactive contamination (section Biological effects)X-rays, neutrons or beta particles pose the greatest risk from an external source. Low penetrating radiation such as alpha particles have a low external risk...
Polonium (section Detection in biological specimens)alive for five months. Polonium-210 may be quantified in biological specimens by alpha particle spectrometry to confirm a diagnosis of poisoning in hospitalized...- Radiation protection (redirect from Biological shield)neutron flux in nuclear reactors. Alpha particles (helium nuclei) are the least penetrating. Even very energetic alpha particles can be stopped by a single sheet...
Neutron radiation (section Effects on materials)reactors or particle accelerators, including the Spallation Neutron Source. Neutron radiation was discovered from observing an alpha particle colliding...- 1 Gy by alpha particles will lead to an equivalent dose of 20 Sv, and an equivalent dose of radiation is estimated to have the same biological effect as...
- possible to quantify tridymite in the presence of alpha-quartz or cristobalite [69]. Matrix effects from interferences with other silicates (such as kaolinite)
- antiparticle "partners" of corresponding "ordinary" matter particles. Antiparticles are generated in particle accelerators (total production of which is a few nanograms)
- three alpha-particles with energies of 5.66, 5.82, 5.89 MeV. Finally it is useful to note that alpha-particles are very damaging biologically and this
