论文摘要
我们使用Monte Carlo模拟研究了用于扩散α-发射机辐射疗法（DART）的种子中辐射-224子核的释放。计算出的polonium-216（15％）和Lead-212（12％）的解吸概率表明，它们对从种子中的总释放做出了重要贡献。我们还表明，10mm长种子内部腐烂的剂量超过2.9 Gy，初始辐射224活性为111 kBq。
We used Monte Carlo simulations to study release of radium-224 daughter nuclei from the seed used for Diffusing Alpha-Emitters Radiation Therapy (DART). Calculated desorption probabilities for polonium-216 (15%) and lead-212 (12%) show that they make a significant contribution to total release from the seed. We also showed that the dose to tissue from decays inside the 10mm long seed exceeds 2.9 Gy for initial radium-224 activity of 111 kBq.
