Abstract: | Radioactive Labelling of Chlorofluorohydrocarbons by Gamma Radiation Chlorofluorohydrocarbons were irradiated with high-energy gamma radiation in an electron linear accellerator. The (γ, n) reaction and the recoil of the hot 18F atoms led to the production of labelled compounds which could be used in pharmacokinetic investigations and as diagnostic agents for lung scintigraphy. |
