This dialog allows you to setup the isotope ratios for the Depleted or Enriched Uranium (DU or EU) Series. After setting up the series, you access the Uranium DCGLw Entry dialog for the series by clicking the OK button.
The appropriate setup of radionuclides is discussed in Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (EPA 2000). This document is currently available at: https://www.epa.gov/radiation/multi-agency-radiation-survey-and-site-investigation-manual-marssim
The dialog contains the following controls:
Enter U-235 Weight radio button |
Select to enter the % (by weight) of the U-235 isotope and VSP will concentration values for each of the 3 isotopes in pCi/g. |
Calculate from Sample Data radio button |
Enter the actual sample concentration values of the 3 isotopes in pCi/g, and VSP will compute % (by weight) of the U-235 isotope. |
U-234 Concentration |
Enter the concentration of the U-234 isotope in pCi/g. |
U-235 Concentration |
Enter the concentration of the U-235 isotope in pCi/g. |
U-238 Concentration |
Enter the concentration of the U-238 isotope in pCi/g. |
U-235 Percentage by Weight |
Enter the % (by weight) of the U-235 isotope. Note: a maximum of 3% is allowed for this input. Entering individual concentrations can calculate Highly Enriched Uranium (>3%). |
