Nucleus content of air in occupied rooms

Geofisica pura e applicata Aims and scope Submit manuscript

Summary

1)Indoor concentration is less than outdoor concentration when precautions are taken to prevent indoor contamination of the air; 2) Nuclei are not produced by breathing. The nucleus content of exhaled air is less than that of the inhaled air; the loss appears to be mainly a diffusion loss; 3) Occupancy does not produce any detectable change in nucleus content; 4) A hypothesis is advanced to explain how occupancy might cause a slight decrease in small ion content without causing any increase in nucleus content.

Zusammenfassung

1)Die Konzentration der Kondensatjionskerne innerhalb eines Hauses ist geriuger als jene im Freien, wenn Vorsichtsmassnahmen gegen Verunreinigung der Luft innerhalb des Hauses getroffen werden; (2) Kerne werden nicht durch Atmen erzeugt. Der Kerngehalt der ausgeatmeten Luft ist geringer als jener der eingeatmeten Luft; der Verlust scheint hauptsächlich durch Diffusion zu erfolgen;

3) Bewohnen der Räume scheint keine nachweisbare Aeuderung im Kerngehalte zu erzeugen; 4) Es wird eine Hypothese aufgestellt, wie das Bewohnen der Räume eine kleine Abnahme des Gehaltes an kleinen Ionen erzeugen kann, ohne eine Vermehrung des Kerngehaltes zu verursachen.
