Year 2008

Aus der IUVA-Malayeri-2016-Fluence-Kompilation. Primärstudie: Bohrerova et al. 2008 (Wirt E. coli), LP-Hg 254 nm — geschwänzter dsDNA-Phage (Myoviridae), klassisches UV-Validierungs-Surrogat; sehr UV-empfindlich.

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 1.1 mJ/cm²

D99 99 % 2-log 2 mJ/cm²

D99.9 99.9 % 3-log 3 mJ/cm²

D99.99 99.99 % 4-log 4 mJ/cm²

D99.999 99.999 % 5-log 6.7 mJ/cm²

Morphology & UV-C resistance

Morphology class Non-enveloped (capsid) virus
