The distribution of lead in human teeth, using charged particle activation analysis.
A technique has been developed to measure lead content in teeth using 3He2+ activation analysis. The alpha-activity produced in the teeth is recorded on plastic film alpha-track detectors (LR-115) and compared to the activity produced by the lead contained in standard glass. The concentration in teeth from three areas of the United Kingdom has been determined as a function of age. The lead content is found to increase with age in dentine and pulpal dentine, but not in enamel.
