Abstract

L'INVENTION PERMET LA MESURE CONTINUE ET SIMULTANEE DE LA POROSITE ET DE LA DENSITE APPARENTE DE DEUX SECTIONS VOISINES DE LA CAROTTE 7. LA SOURCE 10 D'ACTIVITE DE RAYONNEMENT INFERIEUR A 5MILLICURIES EST SUPPORTEE PAR LE CHARIOT 3. LE DETECTEUR 2 CONNECTE A L'INTEGRATEUR 24 PERMET L'ENREGISTREMENT EN 19 DE LA DENSITE APPARENTE. LA MESURE DE LA POROSITE DE LA SECTION VOISINE S'EFFECTUE PAR LA DETECTION EN 31 D'UNE ONDE DE FREQUENCE ELEVEE. L'INVENTION S'APPLIQUE A LA MESURE DE LA DENSITE DE PULPES OU DE LA DENSITE APPARENTE DE CAROTTES SUR LE LIEU D'EXTRACTION.
