Sometimes such flares ☀️ are accompanied by outbursts of high-energy radiation ☢️ particles, which can travel near the speed of light and would easily penetrate space vehicle shielding 🛡️. High energy #radiation particles can be a cause of malfunctions in computers and electronics, and they also pose #health risks for #astronauts 🧑🚀 https://www.surrey.ac.uk/news/solar-flare-prompts-close-monitoring-space-weather-ahead-artemis-ii-launch

The 2024 UNSCEAR report (Annex B, Vol. II) outlines key priorities shaping radiation protection 📘
Pages 5–6 offer a concise overview relevant for research, policy, and practice.

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 Report Volume II is comprised of the main text of the 2024 report to the General Assembly (A/79/46) and one scientific annex. Annex B: Evaluation of public exposure to ionizing radiation
#NASA says the #Artemis II crew can ... move equipment 🛍️ around within the capsule to effectively thicken its walls in the direction from which the #SolarStorm is coming
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.
