Radium-226 and Lead 210 in Human Teeth and Bones

Morphological features of the microdistribution of naturally occurring 210Pb/210Po and 226Ra in the teeth of children and juveniles

“…Thus, Manea-Krichton et al (1991) showed a correlation between stable lead in permanent teeth and that in the rib and ulna of adults. Similarly, Lovaas and Hursh (1968) found that in adults 226 Ra and 210 Pb levels in permanent teeth correlated well with those in various bones.…”

“…A summary of these is given in table 6. Note that Czeglédi (1987) Po simultaneously, while Hunt et al (1963Hunt et al ( , 1970 and Lovaas and Hursh (1968) measured 226 Ra and 210 Pb. As in the present work, some workers inferred the level of 210 Pb by measuring a-emission from 210 Po (Lovaas andHursh 1968, Clemente et al 1984).…”

“…Finally, given the association between stable lead in teeth and in bone (Lovaas andHursh 1968, ManeaKrichton et al 1991), and the presence of enhanced 210 Po concentrations at bone surfaces described by Salmon et al (1994Salmon et al ( , 1995, measurements in outer tooth enamel may be of relevance to the dose to bone marrow from this important natural a-emitter.…”
