Excellent book
This is a really good book if you want to learn about scintillation
counting. I do think it is somewhat dated as far as the "newer"
scintillation materials go though. However, since the basics don't
really change there is still much good information in this book
that I have not been able to find any place else.
I have also found the chapter bibliographies very helpful in
identifying additional candidate references. Unfortunately,
many of them are no longer to be found.
I am not a professional in this area.
