N2 - A positron-sensitive, large window single-wire proportional counter was used for measurements of [11C]CO2 in exhaled air after i.v. injection of [11C] acetate. The performance of the proportional counter was studied using Geant4 and Garfield simulation tools as well as experimentally by injections of known amounts of radioactive gas into measuring volume. The proportional counter was found to be sensitive enough for measuring the low concentrations of [11C]CO2 in the air exhaled by patients after i.v. injection of an 11C-labelled radiopharmaceutical. The limit of detection was 200 Bq/L for [11C]CO2.
