The radioisotope Technetium-99m (99mTc) is used in 85% of all nuclear medicine procedures. 99mTc is produced from its precursor Molybdenum-99 (99Mo), whose production is nearly all from one of only five ageing research reactors. Recently a number of accelerator-based methods have been proposed to fill this gap and to diversify this supply chain. In this paper we present a compact (4 m) 10 mA, 3...

this radionuclide is almost exclusively produced from the decay of its parent 99mo. 99mtc is themost available and important nuclide used as a diagnostic agent in nuclear medicine. to develop anewly practical 99mtc generator using ( n,y ) 99mo, an inorganic polymer adsorbent has beendeveloped framed with oxygen-zirconium-chlorine bonds with a high adsorption of mo, thepolyzirconium adsorbent wa...

background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

Background: 99mTc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either supplied by the Iran Atomic Energy Agency or by private companies from foreign countries. In this study we have measured 99Mo contamination in 99mTc elute from different generators in a period of one year. Materials and...
