Abstract

¹⁴⁷Pm is used in industry in sealed radioactive sources for measuring the thickness or density of materials and as a power source in radioisotope thermoelectric generators for space research. Traditionally, ¹⁴⁷Pm is isolated from a mixture of fission fragments of heavy nuclei. An alternative method for producing the radionuclide is irradiation of neodymium with neutrons from a nuclear reactor. At the Research Institute of Atomic Reactors, reactor irradiation of neodymium oxide of natural isotopic composition was carried out and a pilot batch of ¹⁴⁷Pm was obtained.

反应堆生产147Pm

147Pm在工业中用于密封放射源，用于测量材料的厚度或密度，并作为空间研究的放射性同位素热电发电机的动力源。传统上，147Pm是从重核裂变碎片的混合物中分离出来的。另一种生产放射性核素的方法是用核反应堆中的中子照射钕。在原子反应堆研究所，进行了天然同位素组成氧化钕的反应堆辐照，获得了147Pm的中试批次。
