Uranium–uranium dating
Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium-234 (234U) and uranium-238 (238U Other dating techniques using this decay series include uranium–thorium dating and uranium–lead dating. wikipedia.org

Uranium glass - Wikipedia
Uranium glass is used as one of several intermediate glasses in what is known to scientific glass blowers as a 'graded seal'. This is typically used in glass-to-metal seals such as tungsten and molybdenum or nickel based alloys such as Kovar, as an intermediary glass between the metal sealing glass and lower expansion borosilicate glass.

Probability of a disintegration The half-life of Uranium-$238$ is $5×10^9$ years. What is the probability than a uranium atom disintegrates in any one year? I think I have to use Poisson's law but I don't know how t...
the value you are looking for directly, $$\frac{\ln (2)}{5\cdot 10^9} = 1.39\cdot 10^{-10}$$ This is the instantaneous rate of change in the amount of uranium The total amount of uranium is reducing at a rate of $1.39\cdot 10^{-10}$ per year.

How many uranium-238 atoms are left after 1.338 x 10^10 years? The half-life of uranium-238 is about 4.46 x 10^9 years. How many will there be after 1.338 x 10^10 years? How can I figure this out? I know it's exponent...
After every half life, the amount of uranium will halve. So there will be $\frac{1}{2^3}$ as much uranium-238 left.
