The size of a Mo99/Tc99m generator is expressed as the total activity of -Mo99 on the column -Tc-99 on the column -Tc-99 eluted from the column -a and b - ✔✔A: the size of a Mo99/Tc99 generato... r is expressed as the total Mo99 activity on the column at the time of initial assay After a Mo99/Tc99 gnerator is eluted it takes approx how many hours for the Tc-99m actiivty to build up to a maximum level? - ✔✔24 hours to reach max level If a Mo99/Tc-99m generator is eluted at 0700 and again at 1300, the next days Tc-99m yeild at 0700 will be (increased/decreased/unaffected/unpredicatble)? - ✔✔Decreased because the the amount of time between elutions was shorter If 375 mCi Tc99m are present on the column of a Mo99/Tc99m generator and following elution 342 mCi Tc99m are assayed in the elution vial, the approx elution efficiency of the generator is? - ✔✔Elution efficiency = amount eluted / activity in column 342/375 x 100% = 91% If the elution efficiency of a Mo99/Tc99m generator is 96% and 11.7 MBq Tc99m are present on the column, approx how much activity will be removed during elution? - ✔✔X/11.7 = .96 X = 11.7 x .96 X= 11.2 MBq If 1.2 curies Tc-99m are eluted from a generator in a 5.7 ml volume, what is the concentration of eluate?
