Detector comparison
Previous Up Next

 

Semiconductor detectors have become the main type of detector for gamma spectroscopy but there are still circumstances where the scintillation detector is used e.g. where there is limited space. Hence, scintillation detectors should still be considered and the advantages of each should be weighed up. The table below compares both types of detectors:
Scintillation Semiconductor
Older  
Cheaper (10)  
More efficient (10)  
Larger volumes  
Room temp. operation Low temp (77 K)
Large temp. stability Insensitive to temperature
Very sensitive to bias voltage Insensitive to bias voltage
Poor energy resolution (~ 9%) Good energy resolution (~ 0.15%)
