Description

Determination of ash content in lignite samples using beta back-scattering technique was investigated. A 37 kBq 90Sr/90Y source and lignite samples from Mae Moh Mine in Lampang Province were used in this study. It was found that the intensity of backscattered beta was directly proportional to the ash content for 35 lignite samples used for calibration with the correlation coefficient of >0.97. Then the ash contents of 31 lignite samples were determined using the standard chemical method for comparison. It was found that there were only 10 out of 31 samples with discrepancies greater than 5%. The results indicated the feasibility of developing a low-cost device for quick estimate of ash content in lignite
