Development versions

Developmental versions: These versions are in active development, are very likely to contain errors, may not work at all, and may be offline for changes at any time. On the other hand, they have more features than the stable versions. The only reason to use these is if you're participating in the development or if you want to use a particular feature that's not in the stable versions. The stable versions appear on the main index page.

10Be - version 2.2 - in development
Two major changes in version 2.2. First, this version moves to the revised Be-10 standardization and half-life of Nishiizumi (2007). This requires users to enter the normalization standard used for their AMS measurements. Second, there is the option to use a production rate calibration data set of your choice rather than the default production rate calibration data set from Balco et al. (2008).
Calculate exposure ages
Establish a production rate calibration
Go directly to exposure age calculations using default production rate calibration
Go directly to erosion rate calculations using default production rate calibration

36Cl - development:
Proto-Cl-36 calculator from 2002
(Not at all updated. Doesn't do much. Almost manages to calculate the complete production/depth profile. Uses an interesting numerical diffusion scheme.)
Calculate exposure ages:
Single sample: long form
Multiple samples
Calculate surface erosion rates:
Single sample: long form
Multiple samples
