====== Home Decontamination ======

There are many different ways to decontaminate at home. This a non-exhaustive place to document things found on the net.
 
==== Ultraviolet (UV) Germicidal Irradiation ====

Read up on the basics on Wikipedia:

Claims:

253nm wavelength is optiminal. Lamps that are 11-13 watt will cover a distance of 15-20 sq for a duration of about 45-60 minutes. There are low pressure bulbs and medium pressure bulbs[3]. Many UVC lamps form an ozone which will smell, this is in the range of 185nm [2].
