How long can radioactivity be on uranium?

Radioactivity can persist on uranium for billions of years, as uranium has a very long half-life. The most common isotope of uranium, uranium-238, has a half-life of about 4.5 billion years. Uranium-235, another isotope, has a shorter half-life of about 700 million years.

700 million years


How much time takes uranium decays into led?

It takes billions of years for uranium to decay into lead. Uranium-238, the most common isotope of uranium, has a half-life of about 4.5 billion years, meaning it takes that long for half of a sample of uranium-238 to decay into lead-206.

Pu-239 has a half-life of 24,110 years.


Does uranium 238 have the shortest half life?

No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.


What is the halflife of Uranium-239?

The half-life of uranium-239 is 23.45 minutes.


What are the half lives for uranium-235 and uranium-238?

The half-life of uranium-235 is approximately 703.8 million years, while the half-life of uranium-238 is approximately 4.5 billion years.


How do you write half life of uranium 238 as a standard number?

The half-life of the isotope uranium-238 is 4 468 000 000 years.


What is the half life of uranium 238?

The half-life of uranium-238 is about 4.5 billion years. This means that it takes 4.5 billion years for half of a sample of uranium-238 to decay into thorium-234.


What does Half-Life of Uranium 235 mean?

The half-life of Uranium 235 refers to the time taken for half of a sample of Uranium 235 atoms to undergo radioactive decay. It is a measure of the stability of the isotope, with Uranium 235 having a half-life of about 700 million years. This property is important in dating geological samples and in nuclear energy applications.
