What is the half life equation?
You could use this formula:
Where Th = half-life.
M. = the beginning amount
M = the ending amount
One example of how to use the equation:
One of the Nuclides in spent nuclear fuel is U-234, an alpha emitter with a half-life of 2.44 x10^5 years. If a spent fuel assembly contains 5.60 kg of U-234, how long would it take for the amount of U-234 to decay to 0.35? First, break down the complicated equation:
Th= 2.44 x10^5 or 244000
Then plug the number into the equation:
T= 244000 xlog(5.60/0.35)/log(2)
So the Answer is: T= 9.76x10^5 min.
Note: The example was a question from my quiz I took three weeks ago!
