NRCDose Release Notes

Code & Graphical User Interface (GUI) Changes:

  • GASPAR – removed the options for “Print cumulative dose reports only” on the GASPAR main screen This feature is applicable for use with multiple source terms, which is not an option available in current version.
  • GASPAR – On GUI screen input, included a check on the number of Special Locations, limiting the entry to 5 or less.
  • GASPAR – Added an “Info” pop-up message for Humidity, clarifying that absolute humidity (g/m3) should be entered in the temperature is entered as zero (0); otherwise, humidity should be entered as relative humidity as a percentage.
  • GASPAR – Changed the format used for entries on “Options” tab to store entered values as decimal numbers. This corrected calculations when entries were incorrectly recognized as integer values.
  • GASPAR – Included a pop-up message on the “Release time for purges” on the Source Term tab identifying that value must be less than 4380 hours. Use of a value greater than 4380 results in incorrect calculations of doses from C-14 releases.
  • LADTAP – Corrected the “Max Individual Hold-up Time and “Avg Individual Hold-up Time” (in the “Usage/Consumption” tab) to be consistent with Regulatory Guide 1.109 specified values as used for individual and population dose calculations for irrigated foods.
  • XOQDOQ – corrected issue when reading XOQDOQ legacy files.
  • Download a printer-friendly version of change log summary

Code & Graphical User Interface (GUI) Change:

  • Fixed various errors with the GASPAR and LADTAP codes, including issues involving Pathway Factors, Transfer Factors, calculation of biota doses, and error message generation.

Code & Graphical User Interface (GUI) Change:

  • Updated the NRCDose3 installer routine with version 1.1.0, where the installer did not always install the most up-to-date versions of the file.

Code & Graphical User Interface (GUI) Change:

  • LADTAP - For the individual ALARA calculations, user input for dilutions were switched between drinking water and “all other” pathways. The drinking water dilution was being assigned to the calculations for all other pathways and the all other pathways dilution was being assigned to the drinking water pathway. Interface change to correctly apply the dilution factors.

Code & Graphical User Interface (GUI) Change:

  • Support for updated Dose Conversion Factors (DCF) values - Previous versions of NRCDose (LADTAP II, GASPAR II and XOQDOQ) only utilized one set of DCF values, largely those contained in RG 1.109 and based on ICRP-2 methodology. NRCDose3 allows the user to select either the ICRP-2 (Default) DCF values, or those from ICRP-30 or ICRP-72.
