| Popis: | Using Low Level Gamma Spectrometry it has been evaluated the activity (Bq/kg) of 40K, the gamma emisor daugthers of 238U and 232Th and the presence of artificial isotopes due to anthropogenic contamination. The probes used are coral as biodynamic captors. The results show a presence between low and mittel of natural isotopes compared to o!her accumulation processes like sedimentation in soil and agricultural production. The Caribbean side show a higher activity than Pacific for 40K and a similar for 226Ra. Results show low activity for artificial radionuclides with short life (137Cs). |
