Radiation chemistry deals with chemical processes initiated by the interaction of high-energy photons (X-rays) or charged particles (electrons, protons, alpha heavy ions) matter [...]

background: alpha particle irradiation from radon progeny is one of the major natural sources of effective dose in the public population. oncogenic transformation is a biological effectiveness of radon progeny alpha particle hits. the biological effects which has caused by exposure to radon, were the main result of a complex series of physical, chemical, biological and physiological interaction...

The cellular response to ionizing radiation is not limited to cells irradiated directly but can be demonstrated in neighboring "bystander" populations. The ability of mouse embryonic stem (ES) cells to express a bystander effect and the role of the radioresistance gene Rad9 were tested. Mouse ES cells differing in Rad9 status were exposed to broad-beam 125 keV/ microm 3He alpha particles. All p...

There is strong evidence that biological response to ionizing radiation has a contribution from unirradiated "bystander" cells that respond to signals emitted by irradiated cells. We discuss here an approach incorporating a radiobiological bystander response, superimposed on a direct response due to direct energy deposition in cell nuclei. A quantitative model based on this approach is describe...

Hydrogen emission lines can provide extensive information about star-forming galaxies in both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC), Lyman-alpha (Ly{\alpha}), Balmer line (H{\alpha} H\b{eta}) radiative transfer study of high-resolution isolated Milky-Way simulation using Arepo-RT radiation hydrodynamics code with SMUGGLE galaxy formation model. The re...
