Updates to DRAC
March 2026 - update to DRAC v 1.3
Revisions to DRAC:
- Restriction on the largest grain size parameter possible (TI:32-33) changed from 1 000 μm to 10 000 μm
- The conversion factors of Cresswell et al. (2018) have been added and are available for use.
- The alpha grain size attenuation factors of Martin et al. (2014) have been added and are available for use.
- The data tables page has been updated to include the data of Cresswell et al. (2018) and Martin et al. (2014)
- Calculation of the cosmic dose rate and scaled gamma is now allowed for a depth of zero.
- Minor aesthetic modifications to the website have been made.
Revisions to the Supplementary Information
- Updated contents page
- Addition of Cresswell et al and Martin et al datasets
- Extension of grain size attenuation datasets (alpha and beta)
- Updated worked examples for quartz and feldspar to incorporate new datasets (polymineral example remains the same as v1.2)
- DRAC input and output table updated
- References updated
Version 1.2 of DRAC is still available at this link.
August 2016 – update to DRAC v 1.2
Revisions:
- The gamma scaling function was not operational in v1.1. This has been corrected and tested.
- Restrictions on the input of cosmic dose rate parameters (TI:43-49) in the presence of user cosmic dose rate (TI:50-51) has been removed.
- DRAC Input and Output templates are now available in .csv format.
- Aesthetic modifications have been made to the DRAC input and output templates.
