摘要

在参加CCRI(II)-K2之后。Cd-109国际比较，在ifinh /电离辐射计量实验室对a109Cd放射性溶液进行准确的活度标准化。基于这些结果，测量了109Cd衰变后的低能光子（γ射线和x射线）的发射强度：88.03 keV的γ射线和Kα和Kβ x射线（109Ag）。为此，使用了基于HPGe和Si（Li）探测器的两种光谱系统。利用GESPECOR软件进行蒙特卡罗模拟，将放射性标准源的测量与检测效率转移过程结合起来，对光谱仪进行校准。提供了所获得的结果，包括不确定性预算，并与文献中发表的其他数据集进行了比较。这些新数据对今后的109Cd核数据评价有一定的参考价值。

Determination of emission intensity for low energy photons following the decay of ¹⁰⁹Cd.

Following the participation to the CCRI(II)-K2.Cd-109 international comparison, accurate activity standardization of a¹⁰⁹Cd radioactive solution was performed at IFIN-HH/Ionising Radiation Metrology Laboratory. Based on these results, measurements of the emission intensity for low energy photons (gamma- and X-rays) following the decay of ¹⁰⁹Cd were undertaken: γ-rays of 88.03 keV and K_α and K_β X-rays (¹⁰⁹Ag). For this purpose, two spectrometry systems, based on HPGe and Si(Li) detectors, were used. The calibration of the spectrometers was performed by combining the measurement of radioactive standard sources to a detection efficiency transfer procedure by Monte Carlo simulation with the GESPECOR software. The results obtained, including the uncertainty budgets, are provided and compared to other data sets published in the literature. These new data will be useful for future ¹⁰⁹Cd nuclear data evaluations.

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.
