Some Unique and Interesting Facts about Uranium – Part 1

Uranium is a naturally occurring element with the atomic number 92 and the symbol U. It is a silvery-grey metal that is slightly radioactive and has been used for various purposes throughout history. It was first discovered in the late 18th century, and since then, scientists have studied its unique properties and applications. In this article, we will explore some of the most interesting facts about uranium and why it is a significant component.

1. Radioactivity and Half-Life

Radioactivity is the process by which a nucleus of an atom emits radiation, and uranium was the first element discovered to be naturally radioactive. In 1896, French physicist Henri Becquerel discovered that it emits radiation, leading to radioactivity’s discovery. The term radioactivity was coined by Marie Curie, who discovered two new radioactive elements, polonium and radium, in the early 20th century.

Uranium has several isotopes, with uranium-238 being the most abundant. Uranium-238 has a half-life of 4.5 billion years, which means it takes 4.5 billion years for half of the atoms in a sample of uranium-238 to decay. Uranium-235, another isotope of uranium, has a shorter half-life of 700 million years.  

2. Abundance and Mining

It is one of the most abundant elements in the Earth’s crust. To be more specific, it is estimated that there are about 40 trillion tons of uranium in the Earth’s crust, with concentrations ranging from 0.2 to 25 parts per million. There are several types of uranium deposits, including sandstone, vein, and unconformity deposits. Sandstone deposits are the most common, and they are extracted using an in-situ recovery (which enCore Energy officials co-developed and utilize to this day) method. In this process, a benign solution is injected into the deposit to dissolve the uranium, which is then pumped to the surface. Vein deposits are mined using underground methods, while unconformity deposits are mined using open-pit methods.


Uranium is a fascinating element with unique properties and applications. Its discovery and study have led to significant advancements in science and technology, particularly in the field of nuclear energy.
