In this exercise you are to do an efficiency calibration of a Ge-detector. The efficiency to any
detector is dependent on quantities such as the
To calibrate a ã detector we must also take into consideration that a ray will not necessarily be
emitted every time the source disintegrate. The frequency rays are emitted can be found in tables
and is given as the ã intensity, usually symbolised with I . The formula we use to calculate the
efficiency then looks like this:
