Contribution to the cyclotron targetry

The radionuclide18F is of considerable interest for biochemical and physiological studies using positron emission tomography (PET). Of all methods used for its production only two have found wide application since their yield is high enough and the chemical form of the product is suitable for fluorination of organic compounds. Proton irradiation of enriched water using18O(p,n)18F reaction and deuteron bombardment of gaseous neon20Ne(d,α)18F process are the commonly used effective cyclotron production procedures. In our previous papers1,2 the different reactions and target parameters of the deuteron irradiation of neon gas were reported. In the present work, the production yields for the (d,α), (d,n) and (d,p) reactions were determined.
