Promethium (Pm), element #61, got its name from the Greek Titan Prometheus, who stole fire from Zeus and passed it to people. The only element in the lanthanide series of the periodic table with no stable isotopes, Pm has found an impressive number of applications since its announcement in 1947 after World War II. Despite promethium having 38 known isotopes, ¹⁴⁷Pm is by far the most utilized and useful one. Promethium is used in long-life atomic batteries for satellites or space probes, satellite-to-submarine laser communication systems, “cosmic clocks” for the measurement of cosmic rays lifetime, monitoring of the changes in water content of citrus leaves caused by wetting and drying cycles in the soil, radiotherapy, and even for prevention of dandruff, to name but a few applications. During the Moon expeditions, Pm was used to illuminate instruments in the Apollo landing modules; currently it is used during preparations for long-term interplanetary missions (e.g., Mars) to simulate space conditions on Earth. This mini review offers a comprehensive illustration of promethium's history, synthesis techniques, properties, and its major applications in science, technology, and everyday life.

meth（Pm），元素＃61，得自希腊泰坦·普罗米修斯（Prometheus），他从宙斯（Zeus）偷火并将其传递给人们。Pm是元素周期表中镧系元素中唯一没有稳定同位素的元素，自二战后的1947年宣布以来，Pm已经发现了令人印象深刻的应用。尽管pro具有38种已知同位素，但^147种到目前为止，Pm是使用最广泛和最有用的一种。meth用于卫星或太空探测器的长寿命原子电池，卫星到海底的激光通信系统，“宇宙钟”，用于测量宇宙射线的寿命，监测由湿润和湿润引起的柑橘叶片水分含量的变化。在土壤中的干燥循环，放射疗法，甚至用于预防头皮屑，仅举几例。在月球探险期间，Pm用于照亮阿波罗着陆舱中的仪器；目前，它用于长期的行星际飞行（例如火星）的准备工作，以模拟地球上的太空状况。这篇迷你评论全面介绍了meth的历史，合成技术，性质及其在科学，技术和日常生活中的主要应用。
