Description

After a recall of the factors affecting the response of the soil moisture neutron probe, some results referring to the calibration of several types of apparatus in various soils are presented. Then, the relationships between count rates given by different neutron probes are studied, in order to deduct indirectly their calibration equations. Finally, an order of magnitude of the error, in terms of moisture content, due to the random distribution of the radioactive emission is presented

Abstract (French)

Apres un rappel des facteurs influant sur la reponse de l'humidimetre a neutrons, on presente quelques resultats de l'etalonnage de plusieurs appareils dans des sols differents. On etudie ensuite les relations existant entre les comptages des differentes sondes pour en deduire indirectement des equations d'etalonnage. Enfin on donne un ordre de grandeur, exprime en humidite, de l'erreur sur le comptage brut liee aux fluctuations aleatoires de l'emission radioactive
