Design criteria and performance parameters of an alpha irradiation device for cell studies [PDF]
An alpha irradiation device is described that utilises a commercially available disc-shaped americium-241 source of 8 cm diameter. The alpha particles traverse a moving collimator and the source is rotated to reduce the influence of source ...

Determination of Radionuclide Concentration in Human Teeth in Najaf Governorate, Iraq [PDF]
Introduction: 238U decays with alpha particles emission into 234Th and the series ends with 206Pb. The unstable nucleus loses the energy with emitting ionizing alpha particles for reaching a stable state. It is undergoing alpha decay with decay energy (4.

Fire Hose instability driven by alpha particle temperature anisotropy [PDF]
We investigate properties of a solar wind-like plasma including a secondary alpha particle population exhibiting a parallel temperature anisotropy with respect to the background magnetic field, using linear and quasi-linear predictions and by means of ...

On a Diffuse Reflection of the $ \alpha $-Particles
When β -particles fall on a plate, a strong radiation emerges from the same side of the plate as that on which the β -particles fall. This radiation is regarded by many observers as a secondary radiation, but more recent experiments seem to show that it ...

Breit Hamiltonian and QED Effects for Spinless Particles [PDF]
We describe a simplified derivation for the relativistic corrections of order $\alpha^4$ for a bound system consisting of two spinless particles. We devote special attention to pionium, the bound system of two oppositely charged pions.

Gamma-H2AX foci in cells exposed to a mixed beam of X-rays and alpha particles
BackgroundLittle is known about the cellular effects of exposure to mixed beams of high and low linear energy transfer radiation. So far, the effects of combined exposures have mainly been assessed with clonogenic survival or cytogenetic methods, and the

Influence of Different Types of Radiation on the Crystal Structure of Silicon Monocrystals n-Si
In this work, the influence of alpha particles, protons and gamma rays on the crystal structure and structural characteristics of n-type silicon (n-Si) single crystals was studied using X-ray diffraction.

Two- and three-alpha systems with nonlocal potential
Two body data alone cannot determine the potential uniquely, one needs three-body data as well. A method is presented here which simultaneously fits local or nonlocal potentials to two-body and three-body observables.
