Because of the cascade of secondary particles, including neutrons, produced in the shielding of large spacecraft, it is important to test the reliability of electronic devices exposed to energetic (fast) neutrons. Additionally, devices located near a

The CRONUS-Earth and CRONUS-EU Projects have recently examined the reproducibility of cosmogenic nuclide measurements and the ability of cosmogenic-production models to fit high-quality global calibration data sets. In both cases, although results ar

Geological surface-exposure dating using cosmogenic-nuclide accumulation became a practical geochronological endeavor in 1986, when the utility of 10Be, 26Al, 36Cl, and 3He were all demonstrated. In response to the lack of a common basis for quantify

To account for particle interactions in the extracellular (physical) environment, information from the cell-level Monte Carlo damage simulation (MCDS) for DNA double strand break (DSB) induction has been integrated into the general purpose Monte Carl

We present a comprehensive, nuclear-physics-based cosmogenic nuclide production rate model combining radiation transport modeling with excitation functions for commonly measured nuclides. This model allows investigation of factors influencing nuclide

Characteristics of the spallogenic component of nuclide production are investigated through the use of a physics-based model. Calculated production rates for commonly used nuclides indicate differences in scaling up to 15% at very high altitude. Angu

Some potential applications of the isotopes 36 Cl and 236 U require higher sensitivity than is normally required or achieved. For 36 Cl, one such application is the measurement of the 36 Cl/Cl ratio of seawater. We show that, with appropriate precaut

In this study, we use physics based cross sections and the radiation transport code MCNPX to develop a purely physics based global model of cosmogenic nuclide production. Modeling the earth as a series of concentric, spherical shells of various media
