A practical alpha particle irradiator for studying internal alpha particle exposure
Applied Radiation and Isotopes, 2016An alpha particle irradiator has been built in the Radiation Bioengineering Laboratory at Seoul National University (SNU) to investigate the cellular responses to alpha emissions from radon and the progeny. This irradiator is designed to have the energy of alpha particles entering target cells similar to that of alpha emissions from the radon progeny ...

Alpha-particle stripping reactions
Nuclear Physics, 1963Abstract The cross-section for stripping of α-particles from bombarding nuclei, considered according to the α-particle model, has been calculated. The target nucleus is considered to be a black nucleus. The calculations have been carried out with correction for the finite magnitude of the target nucleus and taking the Coulomb repulsion into account.

The Scattering of Alpha Particles by Helium
Proceedings of the Physical Society, 1959Nuclear phase shifts are calculated for the scattering of two alpha particles, using the method of the resonating group structure, and assuming central Gaussian internucleonic potentials and Gaussian wave functions. It is found that a mixture of two-thirds Serber and one-third MHWB exchange force gives good agreement with the experimentally observed ...

The Binding Energy of the Alpha Particle
Proceedings of the Physical Society. Section A, 1954The method of Morpurgo is extended to deal with both central and tensor forces, each having Yukawa-type radial dependence. The method is applied to calculate the binding energy of 4He for one set of Pease-Feshbach force parameters. It is shown that the inclusion of a second D state in the trial wave function leads to a large increase in binding energy.

The Scattering of Alpha-Particles in Helium
Physical Review, 1941Deviations from the scattering to be expected on the basis of an inverse square law of force between alpha-particles receive a satisfactory interpretation in terms of the influence on particles of zero, two and four units of angular momentum of a specific nuclear interaction having a range less than 9\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{

Alpha-particles for targeted therapy
Advanced Drug Delivery Reviews, 2008Alpha-particles are helium nuclei that deposit DNA damaging energy along their track that is 100 to 1000 times greater than that of conventionally used beta-particle emitting radionuclides for targeted therapy; the damage caused by alpha-particles is predominately double-stranded DNA breaks severe enough so as to be almost completely irreparable.

Radiobiological effect of alpha particles. The scientific basis of targeted alpha-particle therapy
Nuclear Medicine and BiologyTargeted alpha therapy (TAT) uses alpha-emitting radionuclides to deliver high-energy radiation directly to a specific biological target. TAT has shown promising results in the treatment of advanced metastatic disease and has demonstrated greater efficacy than beta radiation in inducing apoptosis, mutations, carcinogenesis, chromosomal aberrations, and

Energy Loss of Alpha Particles in Tissue
Radiation Research, 1968Stopping powers of alpha particles have been measured for CO2, O2, N2, and CH4 over an energy range from 0.1 to 5.3 MeV. From these measurements atomic stopping cross sections of alpha particles in tissue (H, 10.1%; C, 12.1%; N, 4.0%; O, 73.6% by weight) have been evaluated.
