Abstract
The present invention provides a radiation transmission-suppressing film that can protect an imaging apparatus from a radiation without adversely affecting the imaging performance of the imaging apparatus. The radiation transmission-suppressing film of the present invention includes a polyvinyl alcohol-based resin film containing boric acid, wherein a product of a boric acid content (wt %) in the polyvinyl alcohol-based resin film and a thickness (μm) of the polyvinyl alcohol-based resin film is 500 or more.
