Abstract  

A very slow extraction of radiosodium with water from the ashed rabbit bone was observed (T=375 h). Thus, the ashing procedure does not facilitate the sodium release from the bone mineral. The mineral is even modified in such a way that sodium ions are then fixed more strongly than in the native bone (formed experiments with native bone yielded a two-exponential curve with T values of 4.36 and 167 h).
