There are many different detectors for different radiation,such as NaI,HpGe,CsI for $\gamma$ detection,and ionization chamber,proportional counter,Geiger counter for $\alpha$, $\beta$ detection,but how to select a suitable detector for different radiation?I mean compare between them,what is the advantages and defects of them?
In some sense the question is simple too big. I mean, it always comes down to a balance between your ultimate goal, your budget and any engineering constraints imposed by the goal.
Consider the differences between
all the way up to things like
Like any other engineering situation we trade things off in order to get what we need (and maybe some of what we want) as easily as possible. In each case we consider things like
Generally scintillation detector is used in the detection and measurement of gamma, beta and alpha activity. However, scintillator kept above the photomultiplier tube within the sealed detector differs in each case.
