Japanese Nuclear Emergency: Radiation Monitoring
RadNet Deployable Monitoring Data
This site contains information and data from March 11, 2011 to June 30, 2011. EPA has returned to routine RadNet operations. This site will continue to be available for historical and informative purposes.
EPA has 40 deployable radiation air monitors that can be sent anywhere in the United States to gather additional data. The RadNet deployable monitors have built-in weather stations and measure gamma radiation. Like all RadNet radiation air monitors, the RadNet deployable monitors send both weather and gamma radiation readings to EPAs National Air and Radiation Environmental Laboratory, hourly.
