Every restoration and cleaning job comes with its own distinct complexities that influence how a project is approached. For odor removal and disinfection jobs, factors such as the type of structure layout, source of the odor, and project timeline all impact what type of device should be utilized and how it should be applied. When it comes to using UV-C for disinfection and odor removal, it is essential to understand what UV-C dosage is and how to apply the correct dose for a successful project outcome.
UV-C light falls between the range of 100-280 nm on the ultraviolet spectrum. UV-C inactivates microorganisms by destroying the DNA and RNA of the organism, rendering it unable to reproduce or carry out necessary cellular functions.
However, understanding the factors affecting UV-C dosage is crucial to effectively using UV-C, as an improper dose can affect the efficacy of the device. The correct term for UV-C dosage, or strength, is fluence. Fluence is the amount of UV irradiation produced by a UV-C device and is expressed as mJ/cm². Fluence can be measured, and the International Ultraviolet Association (IUVA) collects and makes available years of data and underlying scientific publications for known fluences required to inactivate specific pathogens.
Calculating fluence can be complicated and requires the use of special equipment. For this reason, we provide our clients with coverage area recommendations based on the data gathered from the extensive testing done by the IUVA. Following the coverage area recommendations and the operating manual helps ensure projects receive the necessary exposure to remove odors effectively.
The necessary UV-C dose can be impacted by several factors. One of the most important components to remember is that if air cannot get to an object, neither can the oxidants from a UV-C device. Additionally, adding some type of air movement and creating a vortex when possible is recommended to disperse the UV-C oxidants further.
Consider these factors when using a UV-C device on a cleaning or restoration job to ensure you achieve the correct dosage:
