Abstract

High-resolution CT scanning of teeth with a resolution on the 20 to 30 μm scale introduces doses in the range of 250 to 420 Gy in the tooth enamel. If the induced doses cannot be precisely estimated, subsequent ESR dating analysis becomes impossible. Considering the increased availability of portable, high-resolution CT scanners, curators of valuable human dental fossils have to make an informed decision whether they want to preclude ESR analysis, one of the few dating methods that can be applied to older fossils.
