Abstract�� The aircraft fuel density measuring system by utilizing the radioactive isotope was introduced. A method of correcting the measuring data and a scheme of twin-detectors measuring system were led by efforts to solve the initial intensity fluctuation of the radioactive source in the measuring procedure. Then the principles of these two solutions were discussed in detail.
