Homework Statement
A sample of radioactive isotope is found to
have an activity of 120 Bq imediately after it
is pulled from the reactor that formed the iso-
tope. Its activity 1 h 55 min later is measured
to be 85.8 Bq.
Find the decay constant of the sample. An-
swer in units of h^-1.
Homework Equations
1Bq= 1 decay/sec ln(2)/k= t(half-life)
The Attempt at a Solution
120-85.8/(115*60)?
