an intraoral outer envelope;

a film chip disposed within the intraoral outer envelope; and

a non-lead shielding sheet disposed within the intraoral outer envelope adapted to absorb backscatter radiation when exposed to a source of radiation, the non-lead sheet being comprised substantially of tin, the non-lead sheet being comprised of at least 99.95 percent tin.

7. The intraoral x-ray film packet according to claim 6 , wherein the non-lead sheet is disposed on one side of the film chip such that, when the film chip is exposed to a source of radiation to capture the intraoral image, the film chip is intermediate the source of radiation and non-lead shielding sheet.

8. The intraoral x-ray film packet according to claim 6 , wherein the non-lead sheet is comprised of about 99.975 percent tin.
