The artificial radioactivity levels in Brazilian seawater are typical values due to fallout deposition.801-804openAccessseawaterbrazilradioactivitycesium 137strontium 90plutonium 238plutonium 239plutonium 240precipitationgamma spectroscopyalpha spectroscopycontaminationArtigo de periódico324810.1023/A:1010673602722
