Natural radioactivity in European drinking water: A review

Critical reviews in environmental science and technology, 2022
More than three quarters of the dose from ionizing radiation is caused by natural radiation sources. In most European countries, groundwater is used as a source of drinking water, what can be an additional source of radiation since naturally occurring ...

Bedrock radioactivity influences the rate and spectrum of mutation

eLife, 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

Ecological 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.
