Abstract. We present the injectivity and support results of the Radon transform for the double fibrations of semisimple symmetric spaces in the setting of the inclusion incidence relation which generalizes the setting of our previous result in [Ish2]. We also generalize the projection slice theorem which relates the Radon transform with the Fourier transforms on semisimple symmetric spaces.
