AbstractAbstract
[en] This work shows the monitoring interval, which can be implemented in the Laboratorio de Contaminacion Interna del Centro de Proteccion e Higiene de las Radiaciones, for direct measurement in the thyroid gland of radionuclides 125I and 129I . Were used two measuring systems, one employing a scintillating detector and the other detector Phoswich. Both detectors were placed inside a depth camera, 2.5 x 2.5 x 2.5m of dimension covered with 15 cm of steel, 3 mm lead, 1.8 mm tin and 1.5 mm of copper. Was calculated for each system, the minimum detectable activity, and based on this, the monitoring interval is determined. Was obtained, for 125, all tested intervals, 120, 90,60,30 , 14, and 7 days may be implemented with both systems. In the case of the radionuclide 129 I, with the installation of scintillating detector can only be implemented the intervals 120, 90, and 60 days , and for installation with Phoswich, all evaluated
