Abstract

PARA SUPRIMIR LA INFLUENCIA DE RADIACION EXTRAÑA EN PROCESOS DE MEDIDA RADIACTIVA, SE DETERMINA EL PRINCIPIO Y EL FINAL DE LA RADIACION EXTRAÑA, ASI COMO EL MOMENTO CUANDO ALCANZA UN ESTADO ESTABLE. SE DETERMINA LA DIFERENCIA ENTRE LOS RESULTADOS DE MEDIDA ANTES DE QUE COMIENCE LA RADIACION EXTRAÑA Y LOS RESULTADOS DE MEDIDA DESPUES DE QUE LA RADIACION EXTRAÑA ALCANZA SU ESTADO ESTABLE, Y LA DIFERENCIA ASI DETERMINADA ES DEDUCIDA A PARTIR DE LOS RESULTADOS DE MEDIDA TANTO COMO LA RADIACION EXTRAÑA ESTE PRESENTE. DADO QUE LA DIFERENCIA ASI DETERMINADA CORRESPONDE A LA MODIFICACION DE LOS RESULTADOS DE MEDIDA ORIGINADOS MEDIANTE LA RADIACION EXTRAÑA, LOS RESULTADOS DE MEDIDA OBTENIDOS MEDIANTE DEDUCCION DE LA REFERENCIA INDICADA SON IGUALES A LOS RESULTADOS DE MEDIDA QUE SE OBTENDRIAN SI LA RADIACION EXTRAÑA ESTUVIERA AUSENTE.
