The probabilistic version was updated and released including the following features:
Default data distributions for important variables.
Template files for non-radionuclide dependent variables.
A help system to display the input distributions
Feedback on how long the calculation will take
A robust user input screen for setting distributions, input correlations, & sampling characteristics
An estimate of the variability of the end results given the sampling size and characteristics
A set of 4 output results including interactive tables and graphs, a full report, and a structured database with all the raw samplings and intermediate results.
Input-output correlation analysis
Analysis with both the peak-of-the-means and means-of-the-peaks methods
Windows user interface code upgraded from 16-bit VB4 to 32-bit VB6
Quadruple precision used in Bateman calculations for decy/ingrowth source factors. This is important for decay chains of 5 or longer.
Quadruple precision used in Romberg integrations. This shortened calculations times and completely eliminated convergence failure errors.
Improved integrated risk convergence.
Introduced ratio between default DCF and DCF for inorganic C-14
Included occupancy considerations for the inhalation of gaseous C-14 and H-3. Removed consideration of H-3 in particulate form.
Consider evasion losses of C-14 and H-3 for groundwater pathways.
Improved robustness when chain retardation factor ratios widely vary in different zones.
Add ability to perform non-integrated risk (1 point).
Improved radon progeny risk calculation.
