Influence of Absorbing Layers on the Average Dose and Dose Uniformity during Irradiation with 1–3 MeV Electrons
Abstract
Electron beams with energies up to 3 MeV, widely used in technological and research practice, have a relatively low penetration depth into matter, and the inhomogeneity of energy absorption can reach 30% per 1 mm of path. High heterogeneity, as well as the high cost of radiation, requires the researcher to have skills in optimizing the uniformity of irradiation and reducing energy losses. This work presents the dependences of the average absorbed dose and dose heterogeneity for irradiation of liquid with a horizontal beam in test tubes or tubes with different glass wall thicknesses (0.2–2 mm Pyrex). The dependences are applicable to refining, predicting, and analyzing the distribution of absorbed dose in materials.
