From symposium on noble gases; Las Vegas, Nevada, USA (24 Sep 1973). The radioactive noble gas thoron (/sup 220/Rn) was measured in the breath of dogs following intramuscular injection or inhalation of /sup 228/Th-enriched ThO/sub 2/ . With increased ventilation the amount of exhaled thoron increased both in the injected dogs and in artificially ventilated lungs from dogs that had inhaled ThO/ sub 2/. In general thoron was washed from the lung more efficiently by the normal breathing maneuvers of the intact dogs than by artificial ventilation of their excised lungs It was possible, however, to obtain marked variations in the thoron output by imposing rather bizarre ventilation patterns on the artificially ventilated lungs.
