American Samoa's Governor, Togiola Tulafono, has asked the federal government for radiation monitoring equipment for American Samoa to detect any effect from the damaged nuclear power plants in Fukushima, in Japan.
The United States has set up monitoring equipment for Guam, CNMI, Hawaii and Alaska.
Togiola informed federal agencies that ashes from a volcanic eruption in the Philippines some years ago made their way to the territory.
The governor also asked the federal agencies for monitoring and a study of tuna because this is a highly migratory species.
The tuna that is canned in Pago Pago and shipped to the United States could be caught in the area close to the location of the nuclear power plants under threat, and towards the northwest Pacific near the equator.
The governor says the federal agencies responsible have agreed to his request for a study.
