Abstract
Although radiogenic free radicals are widely used as molecular probes in biological calcified tissues, their nature and their location remain controversial. Apatites in which 13CO32- ions substitute hydroxyl or phosphate ions in hydroxylapatite were synthesized and irradiated. The 13C-couplings show that the carbon-centered radicals are CO2--rather than CO33--the locations of which depend on the type of carbonate and the treatment of the sample.This publication has 7 references indexed in Scilit:
