Abstract
A comparison between neutron capture gamma (n-gamma), compton backscatterin g gamma ray (gamma-gamma) and natural radioactivity techniques was performe d to measure the ash content of coal samples from coal mines in the north o f Iran. The results proved that the neutron-gamma technique is superior to the other two techniques. The standard deviation between the chemical assay s and the neutron-gamma, gamma-gamma and natural gamma predictions are 1.44 , 5.68 and 1.71% ash, respectively. (C) 1999 Elsevier Science Ltd.
