Global real-time dose measurements using the Automated Radiation Measurements for Aerospace Safety (ARMAS) system

Publikováno v: Space Weather. 14:1053-1080

The Automated Radiation Measurements for Aerospace Safety (ARMAS) program has successfully deployed a fleet of six instruments measuring the ambient radiation environment at commercial aircraft altitudes. ARMAS transmits real-time data to the ground

Advances in Atmospheric Radiation Measurements and Modeling Needed to Improve Air Safety

Publikováno v: Space Weather. 13:202-210

Air safety is tied to the phenomenon of ionizing radiation from space weather, primarily from galactic cosmic rays but also from solar energetic particles. A global framework for addressing radiation issues in this environment has been constructed, b

U.S. Government shutdown degrades aviation radiation monitoring during solar radiation storm

Autor: W. Kent Tobiska, Chris Mertens, Justin J. Bailey, Brad Gersey, Richard Wilkins, William Atwell

Publikováno v: Space Weather. 12:41-45

The U.S. Government shutdown from 1 to 17 October 2013 significantly affected U.S. and global aviation radiation monitoring. The closure occurred just as a S2 radiation storm was in progress with an average dose rate of 20 μSv h-1. We estimate that

mBAND analysis of chromosome aberrations in human epithelial cells induced by γ-rays and secondary neutrons of low dose rate

Autor: Premkumar B. Saganti, Francis A. Cucinotta, H. Wu, Megumi Hada, Brad Gersey, Richard Wilkins

Publikováno v: Mutation Research/Genetic Toxicology and Environmental Mutagenesis. 701:67-74

Human risks from chronic exposures to both low- and high-LET radiation are of intensive research interest in recent years. In the present study, human epithelial cells were exposed in vitro to gamma-rays at a dose rate of 17 mGy/h or secondary neutro

Biological Effects of High-Energy Neutrons MeasuredIn VivoUsing a Vertebrate Model

Autor: William S. Dynan, Wendy W. Kuhne, Varghese George, Honglu Wu, Richard Wilkins, Brad Gersey, Stephen A. Wender

Publikováno v: Radiation Research. 172:473-480

Interaction of solar protons and galactic cosmic radiation with the atmosphere and other materials produces high-energy secondary neutrons from below 1 to 1000 MeV and higher. Although secondary neutrons may provide an appreciable component of the ra
