Abstract
Background Radionuclides have important roles in clinical tumor radiotherapy as they are used to kill tumor cells or as imaging agents for drug tracing. The application of radionuclides has been developing as an increasing number of nanomaterials are used to deliver radionuclides to tumor areas to kill tumor cells. However, promoting the efficient combination of radionuclides and nanocarriers (NCs), enhancing radionuclide loading efficiency, and avoiding environmental pollution caused by radionuclide overuse are important challenges that hinder their further development. Methods In the present study, a new small molecule compound (3-[[(2S)-2-hydroxy-3-(4-hydroxyphenyl)-1-carbonyl] amino]-alanine, abbreviation: HN, molecular formula: C12H16N2O5) was synthesized as a linker between radionuclide iodine-125 (125I) and NCs to enable a more efficient binding between NCs and radionuclides. Results In vitro evidence indicated that the linker was able to bind 125I with higher efficiency (labeling efficiency >80%) than that of tyrosine, as well as various NCs, such as cellulose nanofibers, metal oxide NCs, and graphene oxide. Single-photon emission computed tomography/computed tomography imaging demonstrated the biological distribution of 125I-labeled NCs in different organs/tissues after administration in mice. Conclusion These results showed an improvement in radionuclide labeling efficiency for nanocarriers and provided an approach for nanocarrier image tracing.

Abstract
This paper describes the utility of electrodeposition method to prepare (57)Co point sources. A description of the electrolytic cell, the process of (57)Co electrodeposition, encapsulation and quality control of the sealed (57)Co sources is presented. Sources containing ~3.7-4.81 MBq (0.10-0.13 mCi) of (57)Co were prepared, encapsulated in miniature titanium capsules and subjected to quality control tests to ensure compliance with regulatory requirements. The encapsulated (57)Co sources prepared by the reported procedure were found to be effective in routine performance evaluation of nuclear medicine instruments.

Abstract
Abstract
This paper describes the utility of the electrochemical technique for the preparation of a circular planar 204Tl source required for the calibration of beta surface contamination monitors. The electrolytic cell, the experimental set up used and the process of deposition are described. The factors that influence the electrodeposition of 204Tl onto the circular copper substrate were investigated and a careful control has been exercised to ensure an optimum deposition of the 204Tl activity onto the substrate. The morphology of the deposited layer was examined by SEM, AFM and EDS analyses. Sources containing ∼3.7 MBq (∼0.1 mCi) 204Tl on a copper sheet of 20 mm diameter working area were prepared and housed in a holder. Quality control tests on the leachability, distribution of activity and stability of the source were performed to ensure compliance with regulatory safety requirements.

Abstract
Abstract
This paper describes a facile and effective method to prepare 133Ba source exploiting the intrinsic properties of the anodized titanium to electro-deposit 133Ba from an aqueous solution. The process consists of anodization of Ti rod [4.8 mm (∅) × 10 mm (l)] to create a reactive surface to permit cathodic electrodeposition of 133Ba from an aqueous solution. The factors that influence the electrodeposition of 133Ba onto the anodized titanium substrate were identified and a careful control has been exercised to ensure optimum deposition of 133Ba activity onto the substrate. The morphology of the electrodeposited samples were examined by SEM and EDS analyses. Sources containing ∼ 3.7–11.1 MBq (0.1–0.3 mCi) 133Ba were prepared, encapsulated successfully in titanium capsules and subjected to quality control tests to ensure compliance with mandatory regulatory safety requirements.
