Abstract

PARA MEDIR LA RADIACION SE UTILIZA LA LUMINISCENCIA M-CENTRO. SE EXCITA UN CRISTAL LIF (20) CON UN LASER DE 442 NM HE-CD YA QUE LAS MEDICIONES DE ABSORCION EN LIF INDICAN EL PICO DE LA ABSORCION M-CENTRO QUE SE PRODUCE A 443 NM. LA ESTIMULACION DE LASER PRODUCE UN ESTADO EXCITADO DEL M-CENTRO, QUE SUFRE UN CAMBIO DE STOKES MUY BRUSCO. EL PICO DEL ESPECTRO DE LA EMISION M-CENTRO SE PRODUCE A 665 NM CON UN ANCHO-MITAD DE 0,36 EV. COMO LA LONGITUD DE ONDA DE LA EXCITACION DIFIERE SIGNIFICATIVAMENTE DE LA LONGITUD DE ONDA, LA MEDICION DE LA EMISION ROJA PROFUNDA SE PUEDE EFECTUAR SIMULTANEAMENTE CON LA EXCITACION. LA POBLACION DE LOS M-CENTROS AUMENTA CON EL INCREMENTO EN EL DAÑO POR RADIACION, Y POR LO TANTO LA LUMINISCENCIA M-CENTRO PROPORCIONA UNA BASE PARA LA DOSIMETRIA DE LA RADIACION.
