The United States Environmental Protection Agency does not yet see a need to locate monitoring equipment in American Samoa to detect radioactive material from Japan.
Governor Togiola Tulafono had requested monitoring equipment a few days after the Japanese nuclear crisis began.
But a spokesperson for the EPA, Dean Higuchi, says after the tsunami it sent out monitors to locations closer to Japan including Hawaii, Guam and Saipan, which would provide an early warning of radio active material.
"Given that the monitoring that's happening thus far has detected very very low levels of radioactive materials far below levels of public health concern, we'll continue to monitor at the current locations and EPA is confident that the current monitoring locations are providing a good network of coverage and monitoring for all areas including American Samoa."
