Bedrock radioactivity influences the rate and spectrum of mutation

open access: yeseLife, 2020
All organisms on Earth are exposed to low doses of natural radioactivity but some habitats are more radioactive than others. Yet, documenting the influence of natural radioactivity on the evolution of biodiversity is challenging.

Empirical evidence that mean soil contaminant concentration is not a conservative indicator of external exposure to wildlife

open access: yesEcological Indicators, 2023
Adequate information on external exposure is often a limiting factor in ecological risk assessments because of a lack of exposure data for free-ranging animals as they interact with a heterogeneous distribution of contaminants.
