99Tc and 129I are two long-lived, highly soluble and mobile fission products that pose a long-term hazard. A proposed wasteform for the disposal of radio-iodine is iodovanadinite (Pb5(VO4)3I), an apatite-structured vanadate. In this investigation, a

Abstract New modes of production and supply of short-lived radioisotopes using accelerators are becoming attractive alternatives to the use of nuclear reactors. In this study, the use of a compact accelerator neutron source (CANS) was implemented to

101Tc is a lesser studied technetium isotope, but its unique nuclear properties and varying routes of production make it interesting for an array of applications where its shorter half-life can be exploited. Here, the authors review the discovery, nu

Presented are the results of 99mTc and 101Tc production via neutron irradiation of natural isotopic molybdenum (Mo) with epithermal/resonance neutrons. Neutrons were produced using a deuterium-deuterium (D-D) neutron generator with an output of 2 ×

Technetium (Tc) retention on gamma alumina nanoparticles (γ-Al2O3 NPs) has been studied in the absence (binary system) and presence (ternary system) of previously sorbed Fe2+ as a reducing agent. In the binary system, γ-Al2O3 NPs sorb up to 6.5% of

Long half-life biologically active fission products, such as technetium-99, present particular problems for the disposal of spent nuclear fuel (SNF). Technetium is present in relatively high concentrations in fuel (approx. 1kg tonne−1 SNF) and has

The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of
