Abstract

Background: Ferrous sulfate solution is the most widely used as an aqueous chemical dosimeter. In this preliminary present study, we applied ferrous sulfate solution in diagnostic radiology.


Objectives: The aim of preliminary present study was to measure absorbance spectrum of ferrous sulfate solution after exposure to diagnostic medical X-rays in the range of 50 keV up to 100 keV of energy.


Materials and methods: Diagnostic medical X-rays were generated by a medical X-ray machine. Radiation exposure was measured by mean of ionization chamber. Ferrous sulfate sulfate solution with saturated O2 gas was irradiated, resulting in ferric ion production in solution. The optical density of irradiated ferrous sulfate solution was determined by spectrophotometer.


Results: A positive correlation was shown in diagnostic medical X-ray energy with radiation exposure. The optical density at a wavelength of 304 nm was increased as a function of X-ray energy.


Conclusion: This preliminary finding suggested that ferrous sulfate solution with saturated O2 gas showed feasibility to measure radiation dose of diagnostic medical X-rays at 50-100 keV of energy.
