![Radiogenic dose and the benefit of drilling. (a) GCR dose versus depth for constant-depth and steadily exhuming horizons, compared with the depth-independent radiogenic dose. Shading spans the radiogenic dose of the baseline composition at 3 Ga (0.9 MGy) and that of the regional GRS abundances at 3.9 Ga (5.6 MGy). Where a curve crosses the radiogenic level, the two doses are equal. (b) Total-dose reduction at 100–101 and 199–200 cm versus exposure age; dashed lines are the GCR-only shielding factors. Dotted lines mark effective ages for 10 and 100 nm yr−1 exhumation. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Radiation.png?resize=1200%2C720&ssl=1)

Radiation Limits On Amino Acid Preservation And Chiral Measurement At Oxia Planum
[astro-ph.EP] Amino acid enantiomeric excess (EE) is a potential biosignature, but its measurement requires sufficient surviving material as well as preserved chirality.
