In this 3-minute deep dive, I explore a beautiful boutique hotel in Vila Real, Portugal, where schist walls appear to create a distinctive radiological signature. Using a Radiacode device, I measured indoor dose rates of around 0.4 μSv/h. Is this dangerous? For a guest staying a couple of nights, not at all. However, for permanent residency, it offers a compelling case study of how 4π geometry and natural building materials contribute to elevated indoor external exposure.

A 64-hour gamma spectrometry acquisition reveals the isotopic fingerprint of this moderately high-background environment. The primary contributor appears to be the thorium-232 decay series, as evidenced by a prominent thallium-208 photopeak at 2614 keV.
