yes, missing word or jargon 18:49 Nov 27, 2011
I can visualise what it is, I've worked in radiochemical labs that have had this sort of floor covering. Unfortunately, they weren't in English-speaking countries, so I never asked myself what I'd call it in English!
The basic idea, for both radiochemistry and pharmaceutical work, is that you must be able to clean up any spills *completely* without having to demolish the whole building. So you lay in a watertight covering over the floor and the lower part of the wall (about 20cm, if my memory serves me right) that is easy to clean. If you still can't get the contamination off, you take the covering out and replace it, but at least the structure of the lab is OK. |
