The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly, it has been employed to sterilize drinking and wastewater since the holding facilities are enclosed and can be circulated to ensure a higher exposure to the UV. UVGI has found renewed application in air purifiers.

Now GMKJ brings our new UVC LED series 265-280nm LED to the LED industry:

Many of the specifications I have read concerning UV dosage ratings are in microwatt seconds/cm2. For example, one such unit is rated at 16,000 microwatt seconds/cm2. I notice a UV dosage in your calculations or 87 mW/cm2. How do you convert this number to microwatt seconds/cm2?

Most scientists and engineers in the UV business now use the units "mJ/cm2" (millijoule per square centimeter) or "J/m2" (joule per square meter) for UV dose (the correct term is "fluence"). The units "J/m2" are used in most parts of the world except for North America, where "mJ/cm2" are used (1 mJ/cm2 = 10 J/m2. The old term "mW-s/cm2" (milliwatt-second per square centimeter) is equivalent to "mJ/cm2", since a "W-s" is the same as a "J" (joule). Note that 1000 microwatt = 1 milliwatt.

Note that the term "dose" ("dosage" is a word that is redundant with "dose" and should be discouraged) is normally applied in situations where the radiation is totally absorbed (e.g., UV in sunlight absorbed by the skin to cause sun tanning or sun burning). Since less than 1% of the UV incident on a microorganism is absorbed, the term "dose" is not appropriate for this situation. This is why the term "fluence" (which is defined in terms of UV "incident" on a tiny sphere from all directions) is more appropriate.

The units "mW/cm2" (for fluence rate or irradiance) are often confused (as you have in your question) with the units "mJ/cm2" (for fluence or UV dose). The "fluence" (UV dose) is obtained by multiplying the "fluence rate" (or irradiance) (units "mW/cm2") by the exposure time in seconds

Is it possible to use UV lamps to protect postal workers from the terrorist threat of Anthrax contamination of mail?

Very little is known about the inactivation of Anthrax spores by ultraviolet light in air. One would have to arrange that the UV irradiance would be high enough so that the spores would receive a sufficient UV dose. If one were to set up such an arrangement, there would have to be safeguards to avoid exposing the workers' eyes to UV and also the workers should wear latex gloves to block UV from exposing the skin of the workers.
