The average human generates when sitting about 100,000 particles per cubic foot. The acto of sitting down or standing up generates a further 2,500,000 particles per cubic foot. Walking generates about 10,000,000 particles per cubic foot.

Everyone that enters the cleanroom must wear an all over bunny suit - to protect the cleanroom environment from them!
