France will send half a million iodine tablets to French Polynesia in response to the nuclear accident in Japan.
The French high commission in Papeete says the measure is being taken despite the absence of any risk to the territory at this stage.
The iodine tablets will be sent by plane and stored by the French military.
The nuclear test veterans association in Tahiti has meanwhile criticised the authorities for alleged misinformation.
It notes their silence on reports about the risks emanating from the former nuclear weapons test site on Moruroa atoll which experts say could collapse because of the impact of the 147 underground tests.
The group says the French atmospheric test produced radioactive fallout 1,000 times higher than the safe limit.
Last year, Paris adopted a compensation law that for the first time acknowledged that the French weapons tests were not clean.
