How much do Ga-, Lu- and I-based radiopharmaceuticals contribute to the global radiation exposure of nuclear medicine staff?
EJNMMI Phys
November 2024
Department of Diagnostic Sciences, University Hospital Ghent and Ghent University, Ghent, Belgium.
Background: The radiation exposure of nuclear medicine personnel, especially concerning extremity doses, has been a significant focus over the past two decades. This study addresses the evolving practice of NM, particularly with the rise of radionuclide therapy and theranostic procedures, which involve a variety of radionuclides such as Ga, Lu, and I. Traditional studies have concentrated on common radioisotopes like Tc, F, and Y, but there is limited data on these radionuclides, which are more and more frequently used.

Article Synopsis
- Copper is a versatile transition metal with two stable isotopes that have applications in various fields, including geology for tracing ore formation and environmental pollution.
- In biology, copper is essential for plants and animals, contributing to critical functions like photosynthesis, growth, immune response, and enzyme activity.
- Despite its importance, excessive copper can be harmful, leading to health issues in humans and detrimental effects on plant growth and function.
Validation of an automated dispensing system for subsequent dose dispensing of different radionuclides.
EJNMMI Radiopharm Chem
February 2024
Department of Nuclear Medicine, Antoni van Leeuwenhoek, Amsterdam, The Netherlands.
Background: Automated dispensing systems (ADSs) for radiopharmaceuticals have been developed to reduce the radiation exposure of personnel, to improve the accuracy of the dispensed dose and to limit the microbiological contamination. However, before implementing such systems, validation according to various applicable guidelines is necessary to ensure safety and quality. Here we present the selection, validation and implementation of the PT459R2 from manufacturer Lynax s.

November 2023
Facultad de ingeniería, Universidad de América, Avenida Carrera 1 No.20-53, 111711, Bogotá, Colombia.
An integral sampling methodology was applied to the sewerage network of Bogotá by inspecting wells that carry sanitary water from institutions that use I in nuclear medicine treatments to determine the areas of the city with activity of this radioisotope, which may reach the Salitre wastewater treatment plant and are subsequently discharged into the Bogotá river. The areas evaluated included the location of authorized institutions that use I in nuclear medicine and their patients. A total of 13 wells were sampled in the city, each with three samples, and the characterization of the samples was performed using the technique of high-resolution gamma spectrometry with Ge-HP detector and covered the relevant aspects that must be considered to make a complete characterization of the presence of the isotope studied.
