| 摘要 |
<p>The invention relates to a method of preparing a liquid for radiopharmaceutical application comprising a radioisotope by eluting a radioactive daughter isotope from a parent isotope which is adsorbed on an adsorbent by means of a physiological solution, in which a fissionproduced parent isotope is used and the eluate comprising a daughter isotope is purified with a cationexchange material. By using the method according to the invention a liquid containing a radioisotope having an exceptionally high chemical, radiochemical and radionuclidic purity is obtained in a high yield. The invention also relates to an isotope generator system suitable for use of the said method and to a reservoir for said generator system.</p> |
