🌍 Where does radon actually come from? It is a question I get asked more often than you would think.Pages 19 and 20 of the UNSCEAR 2024 Report lay it out clearly: the main sources are natural, rooted in the radioactive decay of uranium and radium present in rocks and soil. But building materials, groundwater, and ventilation all play a role too.

Morning run done — 8.5 km — and straight into ERA Workshop recap mode 🏃🎙️
Yesterday in Bergamo: four talks on radon in water, RadonNet instruments, gamma spectrometry + indoor air risk assessment, and soil gas by Matej Neznal. Roundtable with ~40–45 on site and ~20 online. ERA AGM, Executive Committee meeting, rooftop dinner. ☀️ 25 degrees in Bergamo.
Science doesn't stop. Neither does the training.

The UNSCEAR 2024 Report is out.
This is the most comprehensive review of natural radiation sources available — and radon and thoron are at its core. Updated dose assessments, new epidemiological evidence, and findings that will inform regulation and practice globally.
If you work in radiation protection, environmental radioactivity, or public health, pages 18 onwards are essential reading.

How confident can we really be in radiation risk estimates?
UNSCEAR 2024 Vol. II, Annex B p.17 applies a Bayesian framework to show how exposure and dose measurement uncertainties feed into cancer risk models. Honest science about what we know — and what we don't.
Essential for radiation protection, dosimetry, and public health professionals.

The UNSCEAR 2024 Report Vol. II is the most comprehensive global assessment of public radiation doses to date — covering radon, thoron, cosmic radiation, NORM industries, and human-made sources.
Start at page 16 for an overview of the measurement data behind the entire analysis.
Rigorous data. Global scale. Worth reading.

📘 The 2024 UNSCEAR report draws on a wide range of scientific sources — but the criteria used to select those publications matter enormously for how we interpret its conclusions.
Pages 13–14 detail the methodology. Essential reading for anyone working in radiation protection, environmental health, or public health policy.

When is dose assessment necessary—and how should it be expressed?
Clarity in quantities and units is essential for meaningful radiation protection.
Page 10 of this UNSCEAR report is a concise and useful reference:

In 1986, I was 9 and only vaguely aware of Chernobyl.
Now, working in radiation, I recognise how deeply that event shaped scientific priorities, public perception, and professional paths.
A reminder of the long shadow of major technological events.

The first evaluation of public exposure to radiation dates back to 1958.
Decades later, this foundational work still informs how we assess risks such as radon and protect public health.
A good example of how long-term science shapes policy and practice.

The UNSCEAR 2024 Scientific Report (Vol. II) has been published.
An essential resource on public exposure to ionizing radiation, including radon’s contribution. I’ll share key insights over the coming weeks.

Los niveles de radón pueden variar varios órdenes de magnitud en periodos muy cortos.
Esto hace que las mediciones en continuo sean especialmente útiles para entender su comportamiento y mejorar el control del radón en interiores.

Canada is often highlighted as a strong example of national radon testing efforts.
Yet the Cross-Canada Radon Survey shows that some regions have still never been tested — illustrating why continued measurement remains essential for understanding exposure risks.
