The present report contains three main parts; (I) Droplet nuclei, (II) CFD and (III) Particle distribution. Part I is split up in three minor part. The first part is with one thermal breathing exhaling under different conditions in a ventilated room. It is looked at the exhalation jets trajectory is in the room. In the second part is two manikins located opposite each other. they are located different places in a room ventilated with downward ventilation. it is looked upon how the distance between the manikins effect the personal exposure index. In the third part is two hospitalized manikins investigated. It is looked at how the location in the room, the influence of changed ACH and location of exhaust influence the personal exposure index. Part II is about CFD. CFD predictions are made of the hospital ward to see how CDF fits with measurements and to get a understanding of what happens in the room that is not measured. Part III is about particle deposition, the particle distribution of deposited particles on the floor are found for a single manikin exhaling particles and with two manikins opposite each other where only one of them exhales particles.
