Some Unique and Interesting Facts about Uranium – Part 2

In the previous article, we explored four unique and interesting facts about uranium: its radioactivity and half-life, its use in nuclear energy and weapons, its abundance and mining, and its benefits when used in medicine. In this sequel, we will continue to delve into other fascinating aspects of uranium.

5. Color and Fluorescence

Uranium has a unique color and fluorescence under UV light. It is a silvery-grey metal, but when it is finely divided, it appears black. Uranium also has a greenish or yellowish tint due to its oxidation state. When exposed to UV light, uranium fluoresces with a bright green or blue glow, making it easy to detect in low concentrations.

Uranium glass, also known as Vaseline glass, was popular in the late 19th and early 20th centuries. It was made by adding small amounts of uranium to molten glass, giving it a bright green or yellow color. Uranium glass was used to make decorative objects such as vases, bowls, and cups. Today, it is still collected and admired by enthusiasts.

6. Astrobiology

Uranium plays a significant role in astrobiology and the search for extraterrestrial life. Uranium isotopes can be used to determine the age of rocks and meteorites, providing valuable information about the formation of the solar system and the early Earth.

In addition, uranium is a potential energy source for microbial life in extreme environments, such as deep-sea sediments and the subsurface of Mars. Some bacteria can use uranium as an electron acceptor in their metabolism, allowing them to survive and thrive in environments where other organisms cannot.

7. Nuclear Medicine

Radiation therapy and nuclear medicine both employ uranium. Its isotopes have their uses in the diagnosis and treatment of a variety of ailments, including thyroid conditions and cancer. For instance, uranium-235 can be utilized in the production of radioactive isotopes such as technetium-99m, which is frequently utilized in diagnostic imaging procedures in the medical field.

Uranium ions with a high level of energy are typically utilized in radiation therapy to kill cancer cells. This treatment is extremely targeted, and in some instances, it can be more effective than more conventional forms of chemotherapy.


Indeed, uranium is a fascinating element with many unique properties and applications. From its color and fluorescence to its role in astrobiology and nuclear medicine, uranium has played a significant role in science and technology. However, the environmental and health risks associated with uranium mining and nuclear energy cannot be ignored. We must continue to study and understand the impact of uranium on society and the environment while exploring alternative energy sources and waste management solutions.
