Abstract
Gafchromic EBT3 films were analyzed for their response towards ultraviolet UV-A and UV-B doses of solar radiation. This work was done to investigate the ambient daytime UV dose through the color changes of external beam therapy films, in other words EBT3 that was quantified using a visible absorbance spectroscopy technique. The experiment was conducted by exposing the EBT3 films to ambient solar radiation at several randomly selected places around Universiti Sains Malaysia. The experiment was conducted at three different times of the day (namely morning, noon and afternoon) and on two consecutive days, named as Day 1 and Day 2. The results from Day 1 were later combined to form a calibration dataset generating UV dose (mJ/cm2) measurement algorithms while data from Day 2 were combined to form a prediction dataset. From the experiment, the most important single wavelength in generating a highly accurate calibration algorithm was 650 nm. The calibration algorithm was developed using wavelengths of 536, 547, 550, 650 and 693 nm, and the coefficient of determination R2 was recorded at 94.12% with a Root Mean Square Error of Prediction (RMSEP) of 685.85 mJ/cm2. All the empirical results presented in this paper show that EBT3 film is capable of giving a good response in quantifying UV dose.
