Abstract

METODO PARA DETERMINAR EL VALOR DE UMBRAL DE RADIACION DE UN MATERIAL NO METALICO. COMPRENDE: A) IRRADIAR CADA MUESTRA DE UNA PLURALIDAD DE MUESTRAS CON DOSIS DIFERENTES DE RADIACION; B) PIROLIZAR LAS MUESTRAS DE A); C) CALCULAR LA ENERGIA DE ACTIVACION (EA) MEDIANTE LA EXPRESION EA = -BR; D) REALIZAR UN GRAFICO DE LOS VALORES CALCULADOS DE EA PARA TODAS LAS MUESTRAS EN FUNCION DE LAS DOSIS DE RADIACION DE LAS MUESTRAS; Y E) DETERMINAR EL NIVEL DE RADIACION EN EL CODO DE LA CURVA QUE REPRESENTA EL UMBRAL DE RADIACION DEL MATERIAL. SIENDO: R, CONSTANTE UNIVERSAL DE LOS GASES; Y B, LA PENDIENTE DE LA GRAFICA QUE SE CALCULA MEDIANTE EL ALGORITMO DE MINIMO CUADRATICOS DE AJUSTE DE CURVA. SE UTILIZA PARA FABRICAR EQUIPOS EMPLEADOS EN CENTRALES NUCLEARES TAL COMO RELES Y CONMUTADORES.
