Radiation Toxicology, Ionizing and Nonionizing Physical Characteristics of Ionizing Particulate Radiation Of the various ionizing particulate radiations, the most important in terms of likelihood for human exposure are alpha particles, beta particles, protons, and neutrons. Alpha and beta particles occur ...
which expresses the particle’s velocity relative to the speed of light, γ is the Lorentz factor of the particle, Q equals to its charge, Z is the atomic number of the medium and n is the density of the atoms in the volume. For non-relativistic particles (heavy charged ...
Materials and methods: The toxicity of alpha particles and cigarette smoke extract (CSE) was evaluated in terms of DNA double-strand break (DSB) induction and clonogenic cell death of human lung epithelial cells in vitro. The cells were exposed to alpha particles at doses of up to 0.25 Gy ...
Alpha radiation is a type of ionizing radiation that is emitted during the process of radioactive decay. It produces alpha particles, which consist of two neutrons and two protons. When the atoms within matter attempt to balance and need to get rid of excess atomic energy, thiscreates radioacti...
DNA double-strand break (DSB) induction is one of the phenotypes of cellular damage from radiation exposure and is commonly quantified by γ-H2AX assay with the number of excess fluorescent foci per cell as the main component. However, the number of foci
As ionizing radiation is transmitted through human tissue, energy is transferred to the tissue. This can lead to ionization of the atoms or molecules in the surrounding tissue. Alpha particles, which are relatively heavy and have a double positive charge, readily transfer energy to human tissue, ...
The relationship and risks to different bone cells from ionizing radiation from alpha particles emitted from 239Pu relative to bone modeling and remodeling activities are described. The characteristics of the anatomy of skeletal sites and tissues within those sites that are at risk for radiation-induce...
Fisher7, Kai Vetter1,Youngho Seo1,2 & Brian W. Miller8 Targeted radiopharmaceutical therapy with alpha-particle emitters (αRPT) is advantageous in cancer treatment because the short range and high local energy deposition of alpha particles enable precise radiation delivery and ...

It decays with a half-life of 330 days to californium-249, which is a strong emitter of ionizing alpha particles. This gradual transformation is an important consideration when studying the properties of elemental berkelium and its chemical compounds, since the formation of californium brings not ...
