Indoor Air Monitoring

Radon Study


Naval Support Activity Souda Bay began a scheduled one-year study of indoor radon gas concentrations in September 2014.  The study is part of an ongoing Navy-wide radon monitoring program.  Radon detectors were installed in Navy facilities at NSA Souda Bay and Navy-managed buildings at Marathi Pier and NAMFI.
These detectors were placed in basements and ground-level indoor spaces inhabited, or that could be inhabited in the future, at least four hours daily.  Of the 433 pairs of detectors collected and analyzed, 12 were just above the U.S. Environmental Protection Agency (EPA) action level and require mitigation. No housing units tested exceeded mitigation action limits.

Mitigation measures are being taken for the 12 sites above EPA action levels and will be re-tested once mitigation is complete to verify radon levels are below the EPA threshold.  Approximately 80 radon detectors from the year-long study were not found and are being re-tested for six months.  Those sites are currently being re-tested and will also be mitigated and re-tested if found to be above the EPA radon threshold.
