Influence of absorbing layers on the average dose and dose uniformity during irradiation with 1–3 MEV electrons

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 nonuniformity of energy absorption can reach 30% per 1 mm of path. High nonuniformity, 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 dependence of the average absorbed dose and dose nonuniformity when irradiating a liquid with a horizontal beam in test tubes or pipes with different glass wall thicknesses (0.2–2 mm Pyrex). The dependencies are applicable to clarify, predict and analyze the distribution of absorbed dose in materials.
