DETERMINATION OF THE LIQUID LEVEL III A STEEL CYLINDER BY GAMMA ABSORPTION

摘要

The experiments and calculations show that the measurement of the water level inside a 5-inch outside diameter by 2-l/2 inch inside diameter steel tank is feasible. The experimental work indicated that a reduction in gamma-ray intensity of approximately 23 per cent, due to the addition of water inside the cylinder, could be achieved, and measurements of water level with a pre¬cision of ±l/4 inch could be attained. The calculations show that a reduction in gamma-ray intensity of 34 per cent due to the addition of water inside the cylinder is theoretically possible;hence, the experimental reduction factor was 68 per cent of the calculated reduction factor.
