IAEA to help monitor plastic pollution in the Galapagos Islands
The International Atomic Energy Agency announced that its Nuclear Technology for Controlling Plastic Pollution (NUTEC Plastics) initiative has partnered with Ecuador’s Oceanographic Institute of the Navy (INOCAR) and Polytechnic School of the Coast (ESPOL) to build microplastic monitoring and analytical capacity to address the growing threat of marine microplastic pollution in the Galapagos Islands.

In this work, the full energy peak efficiency for a system of two NaI gamma detectors using spherical radioactive sources is evaluated by applying a new numerical algorithm method, since experimental calibration using volumetric sources is a dominant problem of practical gamma spectrometry. The new method is based on the efficiency transfer technique, where the effective solid angles, the effect of self-absorption of the source matrix, and absorption by the source container and the detector housing materials on detector efficiency are considered. The experimental calibration procedure was done using radioactive spherical sources containing aqueous 152Eu radionuclide, which produces photons with a wide range of energies from 121.78 up to 1408.03 keV. The comparison shows good agreement between the measured and calculated efficiencies for the detector using spherical sources.
