Dental x-ray packets having non-lead radiation shielding
View Patent ↗An intraoral x-ray film packet having non-lead radiation shielding for shielding scattered radiation. The packet includes a film chip and a radiation shielding member. The film chip has two sides and the radiation shielding element is disposed on one side of the film chip to provide radiation shielding when the film packet is exposed to radiation. The radiation shielding element is made of a material including a thermoplastic and a non-lead metal powder and/or non-lead metal compound. In one configuration, the film chip and the radiation shielding element are disposed within a light-tight envelope. In another configuration, the radiation shielding element is one side of the envelope, wherein the envelope has two opposing sides, and the chip is disposed within the envelope.
1. An intraoral x-ray film packet, comprising:
an outer envelope including two opposing sheets wherein one of the sheets is comprised of a material including a thermoplastic and a non-lead metal powder and/or non-lead metal compound;
a film chip disposed within the outer envelope; and
a radiation shielding member disposed within the outer envelope, wherein the member is comprised of a material including a thermoplastic and a non-lead metal powder and/or non-lead metal compound.
2. The intraoral x-ray film packet of claim 1 , wherein the film chip and the radiation shielding element are disposed within a light-tight envelope.
3. The intraoral x-ray film packet of claim 1 , wherein the radiation shielding element is a foil thermoplastic laminate.
4. The intraoral x-ray film packet of claim 1 , further comprising a protective covering configured such that the film packet can be disposed within the protective covering.
5. The intraoral x-ray film packet according to claim 1 , wherein the radiation shielding element is comprised of at least 20 percent non-lead metal powder.
6. The intraoral x-ray film packet according to claim 1 , wherein the radiation shielding element is comprised of at least 20 percent non-lead metal compounds.
7. The intraoral x-ray film packet according to claim 1 , wherein the non-lead metal powder and/or metal compound absorbs between about 60 kVp to about 80 kVp of radiation energy.
8. The intraoral x-ray film packet according to claim 1 , wherein the non-lead metal powder is tin, tungsten, zinc, iron, magnesium, titanium, bismuth, copper, aluminum or silver.
9. The intraoral x-ray film packet according to claim 1 , wherein the non-lead metal compound is bromide, sulfide, oxide, chloride, phosphate, phosphite, iodide or nitride.
10. The intraoral x-ray film packet according to claim 1 , wherein the thermoplastic is a polyester, polyethylene terphthalate (PET), PETG, PCTG, polyvinyl chloride, ethylenevinyl acetate, polyurethane, polyamdies, polycarbonates, polyethers, polystyrenes, ABS terpolymers, polymethylmethacrylate, styrene acrylonitrile copolymers, cyclic olefin coplymers, polyethylene, LDPE, LLDPE, HDPE, polypropylene, polysulfone, polyetherether ketone, or polyimide.
