Accumulation of strontium-90 in dental tissues.

摘要: WEANLING rabbits given single injections of 500–1,000 µc. strontium-90 per kgm. showed a high frequency tumours the jaw1, and preliminary histological studies suggest that they arose in close relation to teeth. The amount accumulated individual teeth all one upper quadrant jaw after intravenous injection 100 is Table 1. seen increase with time for at least thirty days then fall abruptly. rabbit grow continuously, lost because layers which strontium initially deposited erupt into occlusion are later worn away mastication. A similar sudden loss from rat may be autoradiographically2.
