1. A radiation image processing device comprising:
a processor configured to:
acquire a first radiation image that is taken from a subject by detecting radiation transmitted through the subject by a radiation detector in a state where an element is interposed between the subject and the radiation detector;
estimate a component of the radiation at a position between the subject and the element, which has passed through the subject, using the first radiation image;
estimate a component of the radiation, which has passed through the element through which the radiation further passes after passing through the subject, using an estimation result of the component of the radiation transmitted through the subject and scattering characteristics of the element; and
generate a second radiation image, in which an image of the subject is formed by the radiation transmitted through the subject and the element, using an estimation result of the component of the radiation transmitted through the element.
