HE USE OF DIGITAL IMAGE PROCESSING IN ANALYSIS OF BORON, CADMIUM IN THORIUM OXIDE WITHOUT CARRIER DISTILATION WITH EMISSION SPECTROGRAPH METHOD

THE USE OF DIGITAL IMAGE PROCESSING IN ANALYSIS OF BORON, CADMIUM IN THORIUM OXIDE
WITHOUT CARRIER DISTILLATION EMISSION SPECTROGRAPH METHOD. The use of digital image
processing in direct determination elements of highly absorption cross-section of thermal neutron such as B and
Cd in nuclear fuel ThO2 without carrier distillation was described. Working and counter electrode should be
modified because volume of the sample was larger than the traditional one. Firstly, analysis of B and Cd in ThO2
was recorded by X-ray film for thorax and then was proceeded by mini digital camera. All files in mini digital
camera were transferred to computer and read by digital image processing of Matlab software. It was found that
all line spectra became Gaussian shape. Since couple of camera position and lightening system had not been
done successfully yet, therefore, quantitative analysis could not been done yet, meanwhile qualitative analysis
had already been done by analysis spectra after image processing. It is easier to analysis B and Cd qualitatively
use of image processing than densitometer instrument.
