近年来,重核裂变产物钷-147在工业上已替代镭-226作为夜光涂料的激发能源而得到广泛应用,用于表面描绘和彩色电视屏等尤为普遍。由于钷-147为纯β辐射体,释放的是软β粒子,又具有适宜的物理半衰期,其主要优点是放射毒性效应远远低于镭,从而可以在使用中减少电离辐射对职业工作者的危害。
In recent years, the heavy nuclear fission product 钷 -147 has been widely used as an exciting energy source for luminous paint instead of radium-226 in the industry. It is particularly popular for surface rendering and color television screens. Because 钷 -147 is a pure beta radiation, the release of soft beta particles, but also has the appropriate physical half-life, its main advantage is that the radiotoxic effect is much lower than radium, which can reduce the use of ionizing radiation on occupational workers harm.
