Particle spread studies (confirming one metre rule)

[teederkee]

Greetings all,

I am looking for a study that illustrates the oft quoted standard that droplet borne particles fall within one metre of their source. This is quoted regularly, but I have not been able to find the study that it is based on.

I regulary show a video that illustrates that the spread can be much higher (http://www.isocapnia.com/SHORT%20Dec...3%20MPEG4.avi). The video uses a low flow oxygen source in order to visualize the particles. Its not high quality, but gets to the point.

Cheers,
Ted

Maybe this will provide a lead:

I think there are more posts on transmission and droplet dispersion in the FT collection.

Particle spread studies confirming 2 metre safety rule ?
