Underground measurements on secondary cosmic rays [PDF]

Measurements made at the Poatina cosmic ray station (41.8 S 149.9 E, 347 m.w.e.) from August 1983 to July 1984 are summarized. The cosmic ray primary particles responsible for events detected at the station have a median primary energy of 1.2 TeV.

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

Cryo‐EM structure of ALC1 in an open conformation bound to a PARylated nucleosome

Acta Crystallographica Section D, Volume 82, Issue 6, Page 683-699, June 2026.
Reanalysis of a publicly available cryo‐EM dataset identifies a new conformation of the oncogenic chromatin remodeler ALC1/CHD1L bound to a PARylated nucleosome. This new structure reveals the position of the macro domain in the complex, and may help to understand the large conformational change leading to the activation of ALC1.Nucleosomes are the ...

Economic impact and effectiveness of radiation protection measures in aviation during a ground level enhancement

Journal of Space Weather and Space Climate, 2015
In addition to the omnipresent irradiation from galactic cosmic rays (GCR) and their secondary products, passengers and aircraft crew may be exposed to radiation from solar cosmic rays during ground level enhancements (GLE).

On the Low Energy Decrease in Galactic Cosmic Ray Secondary/Primary Ratios [PDF]

, 2000
Galactic cosmic ray (GCR) secondary/primary ratios such as B/C and (Sc+Ti+V)/Fe are commonly used to determine the mean amount of interstellar material through which cosmic rays travel before escaping from the Galaxy (Λ_(esc)).

LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...
