Abstract
DETECTOR DE RADIACIONES GAMMA PARA EL CONTROL DE AGUJAS DE COMBUSTIBLE NUCLEAR. COMPRENDE UN ESCINTILOMETRO ANULAR (1) DE YODURO DE SODIO ACTIVADO CON TALIO, DIVIDIDO EN TRES SECTORES (10, 11, 12) AISLADOS OPTICAMENTE ENTRE SI POR CAPAS DE ALUMINA (13, 14, 15), ASOCIADO A UNOS FOTOMULTIPLICADORES (2, 3, 4) CONECTADOS A UNOS MEDIOS DE MEDIDA (7). TAMBIEN COMPRENDE UN DIAFRAGMA ANULAR (6) DE ABERTURA REGULABLE, CAPAZ DE COLIMAR LA RADIACION PROCEDENTE DE CADA PASTILLA CONTENIDA EN LA AGUJA COMBUSTIBLE QUE ESTA SIENDO CONTROLADA, ESTANDO EL ESCINTILOMETRO Y EL DIAFRAGMA DENTRO DE UN RECINTO BLINDADO PARA PROTEGERSE DE RADIACIONES GAMMA EXTERIORES AL DETECTOR.
