| pubmed-article:2648245 | pubmed:abstractText | An improved head-and-neck phantom was constructed from a human skull, cervical vertebrae, and Mix D, a mixture of wax, plastic, and metal oxides with x-ray absorbing and scattering properties similar to water and soft tissues. Lithium fluoride thermoluminescent dosimeters were calibrated and then exposed within the phantom. The doses at 17 anatomic sites were calculated for each of the 18 specific area radiographs in a complete intraoral radiographic survey. | lld:pubmed |
