Comprehensive Radiation Monitoring Plan and Spatiotemporal - PowerPoint PPT Presentation

Comprehensive Radiation Monitoring Plan and Spatiotemporal Distribution of Information Disclosure Ambient Dose Rates Radiation Dose Map Readings of nationwide radiation monitoring are shown in maps. With location search function and location memory function * Select a prefecture. Airborne monitoring Sea area monitoring Real‐time Dose Measurement System Monitoring using airplanes is conducted Relevant ministries and agencies Ambient dose rates measured at mobile on a regular basis, centered on conduct monitoring of seawater, marine monitoring posts nationwide and by the Fukushima Prefecture. The results are soil and marine organisms and release Real‐time Dose Measurement System are compiled into ambient dose rate maps measurement results. shown in a map. and released.
