Abstract: This dental intra-oral film packet configuration includes a film chip and a non-lead radiation shielding member insertable in the light-tight envelope or integral to a wall of the light-tight envelope. The film chip has two sides sensitive to radiation exposure, and the packet protecting the film chip incorporates the radiation shielding fiber powder element on one side of the film chip to provide backscatter radiation equal to the lead (Pb) foil embodiment when the film packet is exposed to radiation. The radiation shielding embodiment is a compounded material of thermoplastic and non-lead metal which couples as the light-shielding member of the envelope or as an insertable shield.

Abstract: There is disclosed an intra-oral x-ray envelope blank for a silver-based x-ray film chip formed of a light opaque front panel member comprised of a base panel portion and an upper enclosure panel portion and a back radiation opaque panel member heat sealed to the base panel portion of the front panel member thereby forming an x-ray receiving film pocket and wherein the upper enclosure panel portion is subsequently folded over the back panel member and sealed thereto and wherein said outer surface of the upper enclosure panel portion include debossed or material relieved slits providing tear directions for accessing the x-ray receiving film chip pocket.
