Abstract

Dose falls-off faster than the inverse square law (ISL) for orthovoltage beams with closed-ended applicators. This work investigates the discrepancy for 30 cm FSD applicators. When using the ISL alone, the maximum dosimetric error would be 3% and 5% at 10 mm and 20 mm from the applicator, respectively, and increases with larger distances. The effective source position was found to be 22.5 cm and reduces the dosimetric error to less than 1.6% for distances less than 20 mm.

评估使用闭端涂抹器的正交电压束偏离平方反比定律的情况第二部分：30 厘米 FSD 涂抹器

对于使用闭端涂抹器的正电压光束，剂量的下降速度比平方反比定律（ISL）更快。这项工作研究了 30 厘米 FSD 施用器的差异。当单独使用 ISL 时，距离涂抹器 10 毫米和 20 毫米处的最大剂量测定误差分别为 3% 和 5%，并且随着距离的增大而增大。有效光源位置为 22.5 厘米，在距离小于 20 毫米时，可将剂量测定误差降至 1.6% 以下。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
