Title: On-Line Prompt Gamma Neutron Activation Analyzers

Abstract

Prompt gamma neutron activation analysis (PGNAA) has become an important method for performing elemental analysis for on-line process control. A major advantage of PGNAA is that neutrons are a very penetrating radiation (200 mm), little influenced by the molecular form, temperature, or physical properties of the process materials being measured. The neutrons reacting with the process materials produce the gamma rays 'promptly' (in picoseconds), and the majority of the gamma rays have good penetrability (300 mm). This offers the advantage of very large analysis volumes, and unlike all other analytical methods, PGNAA has the ability to analyze the entire flow of material. PGNAA analyzers deliver rapid, sampling free, elemental analysis on large top-size, bulk materials moving at many metres per second on conveyor belts or in pipes or chutes. This paper describes some applications of PGNAA, the analysis method, sensitivities, and instrumentation.
