Question

A radioactive source with an activity of 0.2 μCi is used to determine the counting efficiency of a radiation detector. (a) If the response of the detector is 66,600 counts per minute (c/m), what is the detector efficiency? (b) What is the efficiency if the source activity is 20 kBq?

Step 1

Detector efficiency is the ratio of the number of particles detected to the number of particles emitted by the source. It is usually expressed as a percentage. The formula to calculate efficiency (\(E\)) is: \[E = \frac{\text{Number of particles Show more…
