N2 - Accurate calculation of the environmental radiation dose rate (D˙) is an essential part of trapped charge dating methods, such as luminescence and electron spin resonance dating. Although the calculation of D˙ 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˙ calculation for trapped charge dating applications. Users can select from recently published attenuation and conversion factors to make mathematically robust, reproducible D˙ calculations. Comparison of DRAC calculated D˙ values against the published D˙ 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˙ calculations. DRAC will be updated to reflect the latest advances in D˙ 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. Embargo until 31/03/2017
