| Peak summing occurs under close geometry conditions and is a
result of true coincidence summing. To identify these peaks, add the main
peak (highest intensity) to the next most intense peak energy and look to
see if such a peak exists in the spectrum; if this peak does not occur
then try the next most intense peak, and so on.
Summation effects are caused by the coincident detection of two or more
gamma ray photons. |
