摘要： 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.
