LabVIEW, ionization chamber, radiation dose


The purpose of this research was to apply the LabVIEW program to control an ionization chamber for the measurement of radiation dose. Radiation dose of Cs-137 was measured at different distances of 1.0, 1.5, 2.0 and 2.5 m. The results obtained from LabVIEW were compared with those of a manual system. The percentage difference of dose rate obtained from LabVIEW and the manual system was found to be less than 3%. This research work indicated that the LabVIEW can be used in assisting the measurement of radiation dose. Furthermore, by using LabVIEW to control the ionization chamber, the time used for each measurement of radiation dose was found to be reduced by about 50-60 min compared with that of the manual system.
