ResumoAbstract The Mururoa lagoon was sampled immediately after a nuclear test. 131I was found in sediments and plankton. Official French sources explain its occurrence by an accidental release during a control operation. Long‐lived nuclides (137Cs, Pu isotopes, etc) are ascribed to past local atmospheric tests. Their total flux to the Pacific Ocean is markedly low as compared to discharges by major reprocessing plants. Radionuclides short‐term impact on Pacific ecosystems and man is insignificant. Long‐term processes could not be assessed.
