Far-uvc-light-222nm-irradiance-time-distance-power-calculation-tool

When mounting an overhead Far-UVC ceiling light with a ceiling height of 10 feet, there’s a 75% drop in light power from 1 Foot to 2 Feet, but only a 5% drop in light from 4 feet to 10 feet with only 1% of the light power available at floor level.

For those without an intense knowledge of advanced mathematics (or even very basic mathematics for that matter), something such as the inverse-square law can seem incredibly daunting.

There are equations with numbers and variables, references to physics, and many more things which quite frankly seem very boring. For that reason, we’re going to try to cover this in a very practical way, rather than a technical one, and offer tools and charts that will make it even easier for everyone.  It can not be underscored enough how important it is to familiarize yourself with this basic mathematic principle to use the most cutting-edge bio-agent suppression method ever devised in human history – Far-UVC lighting.

The law itself, in AP-UVGI applications, using FAR-UVC light, applies to all lighting in general. It applies to any sort of electromagnetic radiation really. Its most relevant application here is germicidal irradiation using light wavelengths of between 207nm-230nm. This very narrow 23nm band of UV light was discovered as a small UV exposure window much safer for humans yet deadly to pathogens responsible for the current pandemic!

In a nutshell, it teaches how to use UV light as a weapon in the War on Flu! The inverse-square law teaches us how Far-UVC light works over distance and why the distance between your Far-UVC light source and your target area is so important when the amounts of Far-UV light reaching areas are paramount to the safety of people and the effectiveness of UVGI (Ultraviolet germicidal irradiation), or if adding Active Personal into the UV zone than, AP-UVGI, however just think of it as invisible light to keep things simple.

Let’s say we have a light source that is on full power and our bio-agent target is 1 foot away from it.  If our target moves double the distance away from the light (2 feet), how much of the light’s power will reach it? The natural reaction is to think “half power” – but unfortunately that’s now how light works, all light, including germicidal Far-UVC light all follow the inverse-square law of distance.

According to the law, the power of the light will be inversely proportional to the square of the distance. So if we take a distance of 2 and square it, we get 4, the inverse of which would be 1/4 or rather, a quarter of the original light power – not half.

Moving our target 3 feet from the Far-UVC light source (3 * 3 = 9, so 1/9) the power of our Far-UVC light on the target now becomes 1/9th of what it originally was, and this is where time becomes a very important factor for effective germicidal irradiation and for the safety of active personnel in the Far-UV light disinfection zone over extended periods of time.

The below chart shows how the drops in light power work from one Far-UVC light mounted at a ceiling height of 300cm to the floor using a 20-watt 222nm excimer KrCl lamp properly bandpass filtered for a human-safe AP-UVGI application.

The statements made within this website have not been evaluated by the U.S. Food and Drug Administration.  However, the FDA has recognized from its website here that FAR-UVC irradiation is less harmful than legacy UVC and an alternative to hazards low-pressure mercury gas tubes.   Any statements or claims made on this website and the consumer electronic chemical-free UV sanitization products offered by this company are not intended to diagnose, treat, cure or prevent any disease.  Additional UVC light regulation requirements may be needed for sale or distribution in Hawaii, Indiana, New Mexico, Wyoming, and the US Territory of Puerto Rico.

CAUTION: Far-UVC sources have not been tested for photosensitive individuals or those exposed to photo-sensitizing agents.
CAUTION: Far-UVC may help to reduce the number of germs and microbes, but it will not eliminate them.
NOTE: Far-UVC is designed to sanitize air and surfaces using far ultraviolet C (Far-UVC). Research has shown Far-UVC light to be as or more effective in inactivating microbes than UVC light. Unlike conventional UVC, Far-UVC does not require the use of UV protective equipment when UVC wavelengths greater than 230nm are filtered from the Far-UVC light source. [1] [2] [3]
NOTE: The actual inactivation rate of microbes on surfaces and air will vary based on the type of microorganisms and the length of exposure time irradiated.
NOTE: QuantaDose issued a press release that offers an easy spreadsheet calculator tool to help Far-UVC light designers determine time allowance with a known power and distance to help figure out the time necessary to be effective and when the maximum levels of safe 222nm exposure levels are reached under current international standards.

NOTE: Far-UVC is to be used combined with all safety measures and is not intended as a replacement or modification to an existing cleaning and sanitization program.
NOTE: Far-UVC a KrCl emitter has a nominal operational life of >3000 hours.   If the visible dim violet glow is no longer detected, the Far-UVC lamp must be replaced.  A QuantaDose UVC test card is included for Far-UVC light testing as well.
