Non-destructive techniques in activation analysis

Phosphorus determination by derivative activation analysis: A multifaceted radiochemical application

However, in order to expedite matters and avoid cluttering the procedure with needless details, a minimal amount of groundwork is done by the instructor prior to the laboratory period.…”
