UV-C dose–response (D-values)
A D-value is the UV-C dose (in mJ/cm²) needed for a given log-reduction. D90 = 90 % inactivation = 1-log; D99 = 99 % = 2-log; D99.9 = 99.9 % = 3-log, and so on. Values come from the cited study under its specific test conditions.
Reduction log Dose (mJ/cm²)
D90 90 % 1-log 1.2 mJ/cm²
D99 99 % 2-log 2.5 mJ/cm²
D99.9 99.9 % 3-log 3.7 mJ/cm²
D99.99 99.99 % 4-log 5.0 mJ/cm²
D99.999 99.999 % 5-log 6.2 mJ/cm²
D99.9999 99.9999 % 6-log 7.4 mJ/cm²
