(b) In an experiment with 51.80 MBq 99mTc, 5.88×105 counts are
measured in 2 minutes. According to the manufacturer the
sensitivity is 202 cnts/(min⋅μCi) (American manufacturers still use
Ci instead of Bq, 1μCi = 37 kBq). What is the difference between
the sensitivity of the measurement and the factory
specification?
