Japan Materials Testing Reactor (JMTR) of the Japan Atomic Energy Agency (JAEA) has a plan to produce
Mo, which is the parent nuclide of radiopharmaceutical
Tc, by (n,
) method. The
Mo adsorption and
Tc elution characteristics of molybdenum adsorbents should be evaluated since the specific activity of
Mo obtained by (n,
) method is low. Therefore,
Mo adsorption and
Tc elution tests with molybdenum adsorbents for the (n,
) method such as poly-zirconium compound (PZC) and molybdate zirconium gel were carried out under cooperation with the Kazakhstan National Nuclear Energy Center (NNC). As a result, the
Mo adsorption performance of the adsorbents was the same level as conventional data, whereas the
Tc elution performance of the adsorbents was lower than conventional data. The
Mo adsorption and
Tc elution performance will be investigated again in future.
