准确计算环境辐射剂量率（（D）/点）是陷阱电荷定年方法（如发光法和电子自旋共振法）的重要组成部分。虽然（D）在点上的计算在数学上并不复杂，但多个变量的合并和不确定性的传播可能具有挑战性。剂量率和年龄计算器（Dose Rate and Age Calculator，缩写为DRE）是一个开放访问的基于网络的程序，可用于捕获电荷测年应用的快速（（D）过点）计算。用户可以从最近发布的衰减和转换因子中进行选择，以进行数学上可靠的、可重复的（（D）过点）计算。将来自32项研究的422个样品的实际计算（（D）超过点）值与公布的（（D）超过点）测定值进行比较，结果重现性比为1.01 +/- 0.05。预计，该系统将有助于更容易地进行实验室间比较，并将为（D）计算提供更大的透明度。将更新该表，以反映（（D）过点）计算的最新进展，并可在www. aber上免费访问。ac.uk/alrl/drac.

Accurate calculation of the environmental radiation dose rate ((D) over dot) is an essential part of trapped charge dating methods, such as luminescence and electron spin resonance dating. Although the calculation of ((D) over dot) is not mathematically complex, the incorporation of multiple variables and the propagation of uncertainties can be challenging. The Dose Rate and Age Calculator (DRAC) is an open access, web-based program which enables rapid ((D) over dot) calculation for trapped charge dating applications. Users can select from recently published attenuation and conversion factors to make mathematically robust, reproducible ((D) over dot) calculations. comparison of DRAC calculated ((D) over dot) values against the published ((D) over dot) determinations of 422 samples from 32 studies results in a reproducibility ratio of 1.01 +/- 0.05. It is anticipated that DRAC will facilitate easier inter-laboratory comparisons and will provide greater transparency for ((D) over dot) calculations. DRAC will be updated to reflect the latest advances in ((D) over dot) calculation and is freely accessible at www.aber. ac.uk/alrl/drac. The code for DRAC is available from github at https://github.com/DRAC-calculator/DRAC-calculator. (C) 2015 Elsevier B.V. All rights reserved.
