MICROBIAL CONTAMINATION IN CLEAN ROOMS
Abstract
A study to determine the level of microbial contamination in an industrial clean room was undertaken as part of the over-all study of spacecraft sterilization. The level of microbial contamination obtained on a steel surface after exposure to aerial fallout for 52 weeks was essentially the same as the level obtained after the first week. Microbial contamination in the clean room was about one-tenth of that in the adjacent factory area. The airborne microbial contamination in a clean room increased when it was occupied by personnel and rapidly decreased when the room was vacated. Personnel appeared to have little or no effect on the level of inanimate particulate contamination present in the clean room.
