How Do You Know The UVC Disinfection Is Effective?
September 15, 2020 | By MedBot
Combating COVID-19:
Ways of transmission of the virus
- Respiratory droplets on surfaces
- Human contact
- Potentially aerosol in closed space
The virus is venerable to UVGI: generally inactivated by UVGI exposure of only 2-8 millijoules/cm2:
SARS-CoV Disinfection UV-C Dosage | Disinfection time needed (UV-C density >=70uW/cm2) |
Log1 (90%) = 2.1 mJ/cm2 | Log1 = 30 s |
Log2 (99%) = 4.2 mJ/cm2 | Log2 = 60 s |
Log 3 (99.9%) = 6.3 mJ/cm2 | Log3 = 90 s |
Log 4 (99.99%) = 8.4 mJ/cm2 | Log4 = 120 s |
Methods to study effectiveness of UVGI disinfection: [VCU guidance needed]
- Radiometry
- Commercial test cards
- Environmental culture tests
