ERT: Radiological Support

The Environmental Response Team (ERT) provides on-site health physics, technical advice, and support related to radiological contamination in all EPA regions. Support can include federal workers and contractor reach-back support for a wide variety of health physics needs at emergency response and remedial sites for exposure rate, contamination and airborne concentration measurements. ERT can provide nuclide-specific airborne concentration limits for on-site worker protection for respiratory protection and site boundary monitoring. The team has additional caches of standardized radiological instrumentation that regions can use for larger site needs. ERT also houses specialized equipment for remote exposure rate monitoring with the SkyLink and ShortLink systems, swipe and air filter concentration screening, gas flow proportional gross alpha/beta floor monitors, and gamma contour mapping that is compatible with ESRI ArcGIS software tools.
