74 I. If multiple sources of the same radionuclide and/or multiple radionuclides are aggregated at a location, the sum of the 75 ratios of the total activity of each of the radionuclides must be determined to verify whether the activity at the location is less than the 76 category 1 or category 2 thresholds of Table 1, as appropriate. If the calculated sum of the ratios, using the equation below, is 77 greater than or equal to 1.0, then the applicable requirements of this Part apply.
78 II. First determine the total activity for each radionuclide from Table 1. This is done by adding the activity of each individual 79 source, material in any device, and any loose or bulk material that contains the radionuclide. Then use the equation below to 80 calculate the sum of the ratios by inserting the total activity of the applicable radionuclides from Table 1 in the numerator of the 81 equation and the corresponding threshold activity from Table 1 in the denominator of the equation. Calculations must be performed 82 in metric values (i.e., TBq) and the numerator and denominator values must be in the same units.
83 84 R 1 = total activity for radionuclide 1 85 R 2 = total activity for radionuclide 2 86 R N = total activity for radionuclide n 87 AR 1 = activity threshold for radionuclide 1 88 AR 2 = activity threshold for radionuclide 2 89 AR N = activity threshold for radionuclide n 90 Commented [JSJ51]:
The current sum of fractions equation is deleted and replaced with an updated sum of fractions equation. The correction is 91 necessary to make the expression mathematically reflect that an indefinite number of nuclides may be included in the calculation. The change is consistent with the December 2021 92 _________________________________________________________________________ updates to federal rule in 10 CFR Part 37.
