Abstract This paper has analyzed the theoretical basis of applying media interchange to determining air attenuation coefficients, dealt with the scope and condition of its application and formulated a revised formula for the calculation of air gamma attenuation coefficients. The calculation results show that the technique is effective and can play a guiding role in the correct measurement of air gamma attenuation coefficients in airborne gamma survey.
