Abstract

ES CONOCIDO EN UNA CORRIENTE DE POLVO-GAS LA DETERMINACION DE LA PORCION DE POLVO CON LA AYUDA DE UN EQUIPO DE MEDICION DE RADIACION. PARA EVITAR QUE EN LA ZONA DEL DISPOSITIVO DE MEDICION SE DEPOSITEN PARTICULAS DE POLVO EN LA VIA DE RADIACION, QUE PUEDEN FALSEAR LOS RESULTADOS DE MEDICION, SE PROPONE DE ACUERDO CON LA INVENCION, QUE SE GUIE LA CORRIENTE DE POLVO-GAS EN UNA APLICACION, QUE ESTA REVESTIDA POR UNA CORRIENTE DE AIRE PURO Y DE FORMA QUE SE APANTALLA EL LIMITE A TRAVES DE UN TUBO DE VIDRIO EN CONTRA DEL CONTORNO.
