Radioactive gas mixtures

Various 18F-labelled N—F compounds have been obtained175 by reaction of [18F]F2 diluted to 1-2% in Ne with substrates shown in equations 81-86. The radioactive gas mixture has been bubbled through a solution of the substrate, or [18F]F2 produced by the 20Ne(d, a) 18F nuclear reaction has been condensed from the target gas into a Ni autoclave which contained the dry substrate. 

Radioactive gas mixtures. Tritium and carbon-14, usually mixed with inert gases, are commonly used as tracer gases. Krypton-85 mixed with air is used for diagnosing heart and brain disorders.
