Problem 84E

Radon-222 The decay equation for radon-222 gas is known to be y = y0e-0.18t , with t in days. About how long will it take the radon in a sealed sample of air to fall to 90% of its original value?

Step-by-Step Solution:

Step 1 of 4 :

In this problem, we have to find  how long will it take the radon in a sealed sample of air to fall to 90% of its original value.
