摘要
En 中文
When a piece of flint is broken to form an artifact, and then buried in sediment at a site, its outer surface is exposed to a higher beta-particle dose rate than is experienced by the interior of the flint. A layer about 2 mm thick on each freshly broken surface receives an excess P-dose. The difference between the internal accumulated dose and that in the skin can be used to estimate the time elapsed since formation and burial of the artifact. (C) 2000 Elsevier Science Ltd.
