<span style="font-weight: bold">Background: </span>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. <span style="font-weight: bold">Materials and Methods:
</span>The radionuclide impurity of the 99mTc elute were
studied in two types of radionuclide generators (A:
produced in Iran and B: Imported from other country).
<span style="font-style: italic">In-vitro</span> measurements were performed using dose
calibrator. Direct measurements were made, using a
standard canister at the time of milking of the
generators and also in subsequent hours after
milking. <span style="font-weight: bold">Results:</span> The results showed a mean of 99Mo
impurity in generators A and B to be
0.00932±0.0043 and 0.0170±0.0127 respectively.
Although the results showed that the 99Mo
contamination in 99mTc elute was lesser than the
maximum accepted activity limit of 0.015%, the
difference in these two types may reflect different
methods of productions of generator, as well as the
quality control procedures. <span style="font-weight: bold">Conclusion: </span>The mean of
99Mo contamination in generators produced in Iran
Atomic Energy Organization was lesser than
generators imported from foreign origin. Iran. J.
