RadTeamSim.Meter

Features

RadTeamSim.Meter turns your phone into a simulated radiation survey instrument for emergency response training. Load a scenario, move through the real world, and receive GPS-driven radiation readings โ€” no kiosk, computer, or special equipment required. FOUR SIMULATED INSTRUMENTS Switch between a personal radiation detector (dosimeter), gamma survey meter (open/closed window), beta survey meter, and alpha survey meter during any mission. Each instrument displays real-time readings as your position changes within the loaded scenario. REAL-WORLD TRAINING Your phone's GPS drives the simulation. Walk or drive through your actual jurisdiction while practicing field survey procedures, instrument switching, and data recording โ€” the same workflow you would follow in a real radiological response. IMMEDIATE MISSION FEEDBACK Every mission ends with a detailed report: total dose received, highest dose rate encountered, a CDC Health Impact assessment placing your exposure into a hazard category with plain-language health effect descriptions, and a dose comparison to familiar reference exposures like common medical procedures. Your route choices and time in the field translate directly to simulated health outcomes. SAVE FIELD DATA Record surveys and observations with GPS coordinates during your mission. Authenticate into Mission Edge or CBRNResponder to transmit field data directly โ€” your simulated team appears identically to a physical-world responder. STANDALONE OR INTEGRATED Use Meter independently with its own subscription, or as part of a full RadTeamSim.Route and RadTeamSim.Flight SaaS subscription at no additional cost. RadTeamSim.Meter includes a Guest mode to explore all features of the app and experience a preloaded scenario without an account. For functionality with custom scenarios, a RadTeamSim account at radteamsim.com is required.
