A radioactive isotope has a decay constant of 10\(^{-6}\)s\(^{-1}\). Calculate its half-life.
A
5.93 x 106s
B
6.93 x 105s
C
6.93 x 109s
D
5.93 x 107s
Verified Correct Answer: B.
Physical Principles & Numerical Solution
t\(_{1/2}\) = \(\frac{0.693}{\gamma}\) = \(\frac{0.693}{10^{-6}}\)
= 6.93 x 10\(^5\)
