Initial study of regolith exposure ages and burial conditions on Ryugu: Cosmogenic nuclides score in two touchdowns

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Surface processes on the asteroid Ryugu have been investigated using cosmic‐ray‐produced radionuclides, 10Be, 26Al, and 36Cl, and stable noble gases, on eight samples returned by the Hayabusa2 spacecraft. The 10Be and 26Al along with 21Ne measurements indicate that the two Chamber A samples A0105 collected during the first touchdown (TD) were ...

Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

A critical review of radiocarbon in environment

open access: yesDiscover Environment
Radiocarbon is a radionuclide of considerable interest due to its long half-life and high environmental mobility. Since carbon is the biological backbone of the biosphere, radiocarbon can incorporate very quickly into the natural carbon cycle ...

Pesticide prioritization based on risk and model diet proposals for assessing cumulative exposure to pesticide residues in the Brazilian population through food consumption

open access: yesPest Management Science, Volume 82, Issue 4, Page 3853-3873, April 2026.
A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...
