DIAGRAPHY OF NATURAL RADIOACTIVITY IN SURVEYS

摘要

P THE INVENTION RELATES TO A METHOD AND DEVICE FOR DIAGRAPHING NATURAL GAMMA RADIOACTIVITY IN WHICH THE RADIATION DETECTED IN FIVE WINDOWS OF ENERGY IS CONVERTED INTO A DIAGRAPH OF THORIUM, URANIUM AND POTASSIUM TH, U, K CONTENTS FORMATIONS. THESE CONTENTS ARE CORRECTED FOR THE PRESENCE OF GAMMA RADIATION EMITTING MATERIALS (FOR EXAMPLE POTASSIUM) OR GAMMA RADIATION ATTENUATORS (FOR EXAMPLE BARITE OR HEMATITE) IN THE SURVEY FLUIDS. /P
