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...

pharmaceuticals has increased so rapidly in the past few yearsl) that the production and the supply of 99Mo are one of the most important missions of an organization for radioisotope production. Molybdenum-99 having enough high specific activity for the medical application can be produced by nuclear fission of 235U. For the separation of 99Mo from fission products have been reported various met...
A s my year as president of SNMMI gets underway, a continuing focus for nuclear medicine is development of a reliable, domestic supply of radioisotopes. 99mTc remains the most commonly used radioisotope worldwide— used in 20–40 million diagnostic procedures each year. Shortages of 99Mo (the parent of 99mTc), resulting from reliance in recent years on aging reactors, have led to major efforts ar...
Molybdenum-99 is one of the most important radionuclides for medical diagnostics. In 2015, the International Atomic Energy Agency organized a round-robin exercise where the participants measured and calculated specific saturation activities achievable for the 98Mo(n,γ)99Mo reaction. This reaction is of interest as a means to locally, and on a small scale, produce 99Mo from natural molybdenum. T...
1. To investigate the effects of sulphur intake on molybdenum metabolism in sheep, ewes were given intakes of 0.3 or 3.5 mg Mo and 0.98, 1.33, 1.73 or 3.23 g S/d in a 2x4 factorial experiment with two replicates lasting 35 d. 99Mo with 0.1 mg carrier Mo was infused intravenously for the last 14 d and, when 99Mo concentrations in urine and faeces had attained plateaux (days 11-14), stable Mo and...
after 24h no further increases were noted. Table 1 summarizes the general distribution pattern, and the extent of incorporation of 99Mo into protein in male mice after 2 days of oral administration. In a preliminary survey no sexual dimorphism was found. The duodenum had the highest degree of 99Mo incorporation and enzyme activity. Table 1 also shows the corresponding pattern for Drosophila lar...
