Promethium
Promethium (symbol Pm) is an expensive, rare and invaluable element on the periodic table. It is a radioactive metal of the lanthanide series and is considered to be a fissile material, meaning it can be split through a process called fission. This element is difficult to find and as such, relatively few are known. A great deal of research and experimentation is being conducted to evaluate the potential uses of this metal.
Promethium’s most common isotope, Pm-145, has a half-life of about 2.6 years. This makes it an ideal fuel for nuclear studies and power production. Its main application is in nuclear reactors, where the nucleus is split through a process called fission. This splitting of the atom releases energy, which is then used to generate electricity. This is the same process that occurs in a bomb, but without the explosive yield.
Promethium has been used in space exploration to power probes. Its advantage is that it is light, inert and has a long half-life, meaning it can safely be used in space with minimal risk. In addition, it can be safely stored at relatively low temperatures. Promethium is also notably used in pacemakers, as its radiation is directed to specific parts of their human body to stimulate their hearts.
Promethium-147 has been used in medical studies over the years to assess the effects of radiation to the human body. Radiobiological studies have specifically looked at the role of Promethium in radiological processes.
Finally, Promethium may be used as a battery. The battery works through the use of the radiation from the element’s decay process, which is directed to a conductive system that stores potential energy. Although not yet a commercially viable option, research continues to investigate the potential for a Pm-battery in the future.
In conclusion, Promethium’s applications span many disciplines and many, beneficial areas. Although high in cost and difficult to find, the unique properties of this rare and valuable element make it invaluable to the science and technology. With research, who knows what potential use of Promethium is yet to be discovered?
