PURPOSE:To improve sensitivity for X-rays by sandwiching a self-supportable sensitizing sheet prepd. by dispersing phosphor for X-rays in a binder between two sheets of X-ray films sealed in a baglike holder made of a resilient light shielding material. CONSTITUTION:A metallic foil 4 of a size slightly larger than an X-ray film is stuck to the surface on one side of a holder rear surface member 1a consisting of a resilient light shielding material colored white on the outer side and black on the inner side. Then, the metallic foil 4 surface of this member 1a and a holder front surface member 1b are superposed, and the three sides other than the B-B' line are melt-stuck, whereby a holder 1 having an opening part 7 connected to a cover part 6 is obtained. Thence, two sheets of X-ray films 3, 3' are housed in this holder 1, and a self-supportable sensitizing sheet 2 prepd. by dispersing phosphor for X-rays in a binder is sandwiched between these films 3, 3' and the opening part 7 is melt-stuck along the B-B' line, whereby the film pack is obtained. |
