To calculate the depth distribution of radioactive decays in bone by fitting a calculated alpha-particle energy spectrum to a measured spectrum. The dose to bone surface cells is then calculated from the depth distribution.
The spectra are calculated using Monte Carlo methods and a numerical depth distribution obtained by trial and error.
Alpha spectra for 210Po and 226Ra (plus decay products) in bone were calculated and fitted to experimental spectra. The dose to bone surface cells was calculated using the numerical technique and compared to previously published data.
Alpha-particle spectra can be successful fitted using this method, which gives a more realistic distribution of decays with depth than simple surface and volume models.
通过将计算出的α粒子能谱拟合到测量谱，计算骨中放射性衰变的深度分布。然后根据深度分布计算骨表面细胞的剂量。
使用蒙特卡罗方法计算能谱，并通过反复试验获得数值深度分布。
计算了骨中²¹⁰Po和²²⁶Ra（及其衰变产物）的α能谱，并将其拟合到实验谱。使用数值技术计算了骨表面细胞的剂量，并与先前发表的数据进行了比较。
使用该方法可以成功拟合α粒子能谱，与简单的表面和体积模型相比，该方法能给出更符合实际的衰变深度分布。
