The mean recovery rates of the gamma-irradiated SARS-CoV-2 from wastewater. Virus material was concentrated from wastewater samples using PEG6000 precipitation, followed by extraction using the NucleoSpin™ RNA Virus kit and detection by either the Luna® Universal Probe One-Step RT-qPCR Kit or the TaqPath™ 1-Step Multiplex Master Mix kit as indicated. Values are means of three triplicates and error bars indicate standard deviation. P values for the paired t-test comparing the RT-qPCR master mixes are also presented.
