영문 초록

The gamma-gamma logging method appplying in geophysical research are presented in this paper. The logging probe assembly was designed which permits changing the source-to-detector spacing while conditions of proceeding γ-γ logging, which a collimated gamma ray source (⁶⁰Co, 0.5mCi and/or 2 mCi) is separated from the scintillation detector as shown in Fig. 2 and 3, size is 6.0 cm in diameter and 120.0 cm in long and the exposed parts are made of stainless steel pipe. The results is confirmed by the experiment performed mainly in granite rock where a slightly constant shape was obtained but sometimes was shown sharpness shape for the measured scattered gamma-ray intensity. Consequently, the experimental results are obtained an adequate intensity of scattered gamma-rays and favourable response to density change, and also very closely correspond to between core samples of the test boring and to used this method of γ-γ logging in the test bore-hole of the strata.
