A 3-D Dosimeter for Complex-Shaped Foods Using Electron-Beam Irradiation

摘要

A chemical solution composed of paraffin wax, chloroform, and methyl yellow was shaped into a solid 3-D apple-phantom to determine absorbed dose from e-beams. The purpose of this study was to develop a 3-D dosimeter to visualize 3-D dose distribution in complex-shaped food products. Intensity data of an apple-phantom irradiated at 45° with a Van de Graaff accelerator was generated by slicing the phantom into 16 slices, each with 3.175 mm thickness. Three-dimensional representations were produced using the individual data for each phantom slice. The main advantage of using the apple-phantom is that the absorbed dose distribution can be visually seen in 3-D. It clearly helps to demonstrate that the dose distribution and dose depth profiles may be different depending on the reference plane chosen for the dosimetry analysis
