Alpha particle is very dangerous inside the human body, so the study of its interaction parameters for alpha is very important. The Solid-State Nuclear track detector (SSNTD) CR39 can be used to study the different parameters for alpha. In this research, the bulk etch rate (V) measured by using two different methods. The results showed that the measured of V values by the L method is very close to the values measured by the weight method. The average value of V by L method and weight method were 1.26 ± 0.02 μm h - 1.28 ± 0.13 μm h respectively. Also, the results for the range of alpha particles changed from 13.21 ± 0.05 μm for alpha energy 3 MeV to 34.58 ± 0.19 μm for alpha energy 5.48 MeV. The measurement of alpha particles range by the L method for all energies of alpha were very closes to the theoretical range of values. The L method is useful for determining all the different parameters of the path.

使用核径迹轮廓测量 CR-39 探测器中的 α 粒子范围

α粒子在人体内是非常危险的,因此研究其与α的相互作用参数非常重要。固态核径迹探测器 (SSNTD) CR39 可用于研究 α 的不同参数。在本研究中,使用两种不同的方法测量体蚀刻速率 (V)。结果表明,L法测得的V值与重量法测得的值非常接近。 L法和重量法的V平均值分别为1.26±0.02μm·h~1.28±0.13μm·h。此外,α 粒子射程的结果从 α 能量 3 MeV 的 13.21 ± 0.05 μm 变为 α 能量 5.48 MeV 的 34.58 ± 0.19 μm。 L法对所有α能量的α粒子射程测量结果非常接近理论值范围。 L 方法对于确定路径的所有不同参数非常有用。
