DRAC

Dose Rate and Age Calculator

DRAC is designed to calculate environmental dose rates (Ḋ) and ages for trapped charge dating applications. It's applicable to OSL, TL, and some ESR applications, providing standardized calculations with transparent methods.

The Rationale of DRAC

01

Facilitate inter-laboratory comparisons of Ḋ determinations

02

Reduce the potential of mathematical error in the Ḋ calculation process

03

Allow easy and controlled sensitivity testing

04

Represent an ongoing collation of datasets and resources

05

Be a resource for students, teachers, and newcomers to the discipline

DRAC Aims

Comprehensive Calculations

Provide Ḋ calculation for quartz, feldspar, and polymineral samples, over a grain size range of 1 – 1000 μm

User-Friendly Interface

Be easy to use and provide a clear calculation process, with minimum assumptions and maximum user flexibility

Open Access

Be an open access research tool, which is continually updated with the latest datasets and tools

Research Stimulation

Stimulate further Ḋ research and collaboration within the community

DRAC 2.0 is an upgrade of the original DRAC which was designed and developed by Julie Durcan and Georgina King.

We welcome feedback, suggestions, and collaborations from the trapped charge dating community.
