本工作目的是试图利用~(60)Co γ射线辐照朝鲜的硝酸纤维素片,以提高相对灵敏度。在本文中,相对灵敏度定为同样蚀刻时间内,蚀刻终了时,分别以3、4和5MeV的α粒子径迹直径和1MeV α粒子径迹直径之比称之为3、4和5MeV α粒子相对灵敏度。我们对朝鲜硝酸纤维素片,进行了温度范围分别为27、35、40、50、60和70℃的条件实验。在固定温度下,蚀刻剂NaOH的浓度分别为4、5和6N。LiOH浓度分别为4和5N。在每种蚀刻温度和蚀刻剂浓度
The purpose of this work is to try to use ~ (60) Co γ-ray radiation North Korea’s cellulose nitrate tablets, in order to improve the relative sensitivity. In this paper, the relative sensitivities are given for the same etching time. At the end of the etch, the ratio of the diameters of the alpha particle tracks of 3, 4 and 5 MeV to the diameter track diameter of 1 MeV alpha particles is called the 3,4 and 5 MeV alpha particles Sensitivity. We conducted North Korea cellulose nitrate tablets, the temperature range were 27,35,40,50,60 and 70 ℃ conditions experiment. At a fixed temperature, the etchant NaOH concentrations were 4, 5, and 6 N, respectively. LiOH concentrations were 4 and 5 N, respectively. At each etch temperature and etchant concentration
