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.

吸收层对 1-3 MeV 电子辐照期间平均剂量和剂量均匀性的影响
摘要 能量高达 3 MeV 的电子束被广泛应用于技术和研究实践中,但其对物质的穿透深度相对较低,每 1 毫米路径上能量吸收的不均匀性可达 30%。高异质性和高辐射成本要求研究人员掌握优化辐照均匀性和减少能量损失的技能。本研究介绍了在试管或不同壁厚的玻璃管(0.2-2 毫米 Pyrex)中用水平光束辐照液体时,平均吸收剂量和剂量异质性的相关性。这些相关性适用于完善、预测和分析材料中吸收剂量的分布。

期刊介绍: High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
