Radiation: honest talk about exposure and hotspots

📖 Lesson ──▶ 🎯 Quiz — pick the translation ──▶ ✅ Lesson done

Radiation is not just "Chernobyl" — natural background exists everywhere. In Germany the average is ~2 mSv per year — safe. Higher: in the Erzgebirge (old GDR uranium mines, up to 5–10 mSv); in Bavaria near granite rocks (Fichtelgebirge); while flying (+0.1 mSv per transatlantic flight). Chernobyl traces lie in Bavaria and Thuringia — mushroom picking there is officially discouraged.

●Radon in cellars: uplands need ventilation
●Medicine: CT ≈ 10 mSv = 5 years of background, X-ray ≈ 0.1 mSv
●The BfS site maps background radiation by district

⚡ Germany measures with "Messstationen" — a nationwide sensor network. Anyone can check online: background in your city, in real time.
