摘要

The test of production of the 198Au radioisotope by means of Varianmedical linear accelerators used in teleradiotherapy was carried out. Thetargets made of the natural gold (100% of the 197Au isotope) were irradiatedwith high-energy therapeutic 20 MV X-ray beam. 198Au was producedin the simple capture reaction 197Au(n; )198Au. The obtained specific activitiesin the saturation state are relatively low, not exceeding the value of510.4 kBq/g, because only the high-energy part of the spectrum of 20 MVX-ray beam covers the energy range of the neutron production cross section.Low activity of the 198Au radioisotope produced by medical linearaccelerators makes this technique not suitable for a massive production of198Au for nuclear medicine, but the produced amount of 198Au is sufficientfor laboratory tests of new drugs for possible clinical applications.
