Live ambient radiation readings, on one map. RadMap gathers open data from Korea's national monitoring network (IERNet, operated by KINS), Japan's national network (RAMIS, operated by the Nuclear Regulation Authority), France's Téléray network (operated by ASNR, the French nuclear safety and radiation protection authority), and the Safecast citizen sensor network, and shows the current ambient gamma dose rate. WHAT YOU CAN SEE - Live readings from roughly 490 official Korean monitoring posts - Japan's official network across all 47 prefectures, plus the dense grid around nuclear facilities - France's official Téléray network: about 450 stations across mainland France, its overseas territories and around nuclear sites, updated every 15 minutes - Safecast citizen sensors worldwide - Map, list and per-station detail, with the trend over time BUILT SO THE NUMBERS CAN BE READ - Every dose band carries a text label such as "Normal" or "Slightly high" alongside its colour. Colour is never the only signal. - Readings are compared to familiar amounts: one X-ray, one flight, a year of natural background. - Where many stations overlap, they are grouped and shown as an average dose. - All figures use tabular figures, so the layout never shifts as a value changes. WHAT THIS APP PROMISES - The summary at the top of the screen covers Korea. It is calculated from the live readings of official Korean stations, never a pre-written sentence. If any of them rises above its normal band, it becomes an alert. - Every reading carries a provenance badge. Government networks and citizen sensors are never blended together. - Citizen sensors are not cross-calibrated, so they are never used to judge the picture across Korea. - No ads are shown while any official station is above its normal band. PLEASE NOTE This is an unofficial app that presents publicly available data in a readable form. Do not rely on it for official announcements or emergency decisions; for official information, please consult the relevant regulator. Available in Korean, English, Japanese and French.
