A radiochemical neutron activation technique for Mo determination in high purity tungsten, based on some specific properties of Mo and W radionuclides has been developed. Al2O3 powder has been used as a sorbent. An estimation of the Mo content was carried out via the selectively separated99mTc daughter radionuclide. Limit of detection was 10 ng g–1.
