Efficiency simulation and coincidence-summing correction for HPGe detector

He jishu
BackgroundIn order to enhance the detection sensitivity of HPGe detectors for measuring the low-level activity of radionuclides, samples are usually measured as close to the detector as possible to improve the detection efficiency, which inevitably leads

In-situ quantification of gamma-ray and beta-only emitting radionuclides [PDF]

arXiv, 2023
The prompt and in-situ assessment of non-gamma ray emitting radionuclides such as Sr-90 remains an outstanding challenge, particularly in radiological emergency response and consequence management situations. We have developed a new concept to quantitatively assess a wide range of radionuclides, including beta-only emitters, using coplanar-grid CdZnTe ...

Urease-powered nanobots for radionuclide bladder cancer therapy

Nature Nanotechnology
Bladder cancer treatment suffers from low therapeutic efficacy. Here the authors present radioactive ^131I-labelled urease-powered nanobots that exhibit enhanced accumulation at the tumour site, enabling effective radionuclide therapy at low doses as an ...

Current outlook on radionuclide delivery systems: from design consideration to translation into clinics

Journal of Nanobiotechnology, 2019
Radiopharmaceuticals have proven to be effective agents, since they can be successfully applied for both diagnostics and therapy. Effective application of relevant radionuclides in pre-clinical and clinical studies depends on the choice of a sufficient ...
