Radioactive particle tracking (RPT) has emerged as a promising and versatile technique that can provide rich information about a variety of multiphase flow systems. However, RPT is not an off-the-shelf technique, and thus, users must customize RPT for their applications. This paper presents a simple procedure for preparing radioactive tracer particles created via irradiation with neutrons from the TRIGA Mark II research reactor. The present study focuses on the performance evaluation of encapsulated gold and scandium particles for applications as individual radioactive tracer particles using qualitative and quantitative neutron activation analysis (NAA) and an X-ray microcomputed tomography (X-ray Micro-CT) scanner installed at the Malaysian Nuclear Agency.

The potential release of radionuclides threatens marine ecosystems with the rapid development of coastal nuclear power plants in China. However, transport, dispersion, and final budget of anthropogenic radionuclides remain unclear, especially in the Bohai and North Yellow Seas, which are semi-enclosed marginal seas with poor water exchange. This study analyzed anthropogenic I concentration (a typical product of nuclear power plant operations) in seawater samples from this area.

Article Synopsis
- A new theranostic radiopharmaceutical, [Ga]Ga/[Lu]Lu-NYM032, was developed to target prostate-specific membrane antigen (PSMA) for diagnosing and treating prostate cancer (PCa).
- In preclinical studies, [Ga]Ga-NYM032 showed high specificity and uptake in PSMA-positive tumors, outperforming a comparator in detecting bone and lymph node metastases.
- The therapeutic component, [Lu]Lu-NYM032, demonstrated effectiveness in inhibiting tumor growth in animal models, with larger doses leading to significantly smaller tumor sizes.
cutaneous melanoma has often unpredictable lymphatic drainage patterns, especially at the level of the trunk, head and neck regions. Sentinel lymph node biopsy (SLNB) is an important prognostic tool that accurately assesses regional lymph node involvement and guides therapeutic decisions. Material and this prospective study involved 104 patients diagnosed with cutaneous melanoma who underwent SLNB using a radioactive tracer.
