Total Concentration:

a Relative fraction = average concentration divided by the total concentration.

Decay constant = 0.693 divided by half-life.

Sum of DCGL Fractions = .

/ 0 a DCGL fraction = average residual concentration in survey unit (from Section B) divided by the DCGL.

10. Comparison of the sum of the DCGL fractions (D.9) to ALARA AL (C.7):

Check one: Sum of the DCGL Fractions < ALARA AL / Sum of the DCGL Fractions > ALARA AL DPF-8867.1 Rev. Original Page 2 of 3

12. Decision Criteria: If the sum of the DCGL fractions < AL, then additional remediation is not cost beneficial. If the sum of the DCGL fractions > AL, then additional remediation is cost beneficial.

Check one: Additional remediation IS NOT cost beneficial ,/
