Production scheme for diagnostic-therapeutic radioisotopes by accelerator neutrons
Proceedings of the Japan Academy. Series B, Physical and biological sciences, 2021 Interest has been growing in the development of medical radioisotopes used for noninvasive nuclear medicine imaging of disease and cancer therapy. Especially the development of an alternative production scheme of 99Mo, the mother radioisotope of 99mTc ...

Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. II. Advanced modeling of interstellar 26Al, 53Mn, 60Fe, and 244Pu influxes as traces of past supernovae in the solar neighborhood [PDF]
A&A 680, A39 (2023), 2023 Measurements of long-lived radioisotopes provide a means, completely independent of other observational channels, to draw conclusions about near-Earth supernovae (SNe) and thus the origin of the Local Bubble (LB). First and foremost in this context is 60Fe, which has already been detected across the Earth and on the Moon. Using Gaia EDR3, we identified

Short-lived radioisotopes in meteorites from Galactic-scale correlated star formation [PDF]
Proceedings of the International Astronomical Union, 2018 Meteoritic evidence shows that the Solar system at birth contained significant quantities of short-lived radioisotopes (SLRs) such as 60Fe and 26Al produced in supernova explosions and in the Wolf-Rayet winds.

A new method in the production of Ac-227, Ra-228, Th-228 and U-232 on Thorium target from different perspective for use in Radioisotope Power Systems and Nuclear Batteries [PDF]
, 2021 We recommended a new method from different perspective for the production of Ac-227, Ra-228, Th-228 and U-232 radioisotopes which have an important potential for use in radioisotope power systems (instead of Pu-238) and nuclear batteries, based on long half-life, high power density and low radiation level.

Prevalence of short-lived radioactive isotopes across exoplanetary systems inferred from polluted white dwarfs [PDF]
, 2022 In the Solar System short-lived radioisotopes, such as 26Al, played a crucial role during the formation planetary bodies by providing a significant additional source of heat. Notably, this led to early and large-scale melting and iron core formation in planetesimals and their loss of volatile elements, such as hydrogen and carbon.

Investigation of alpha particle induced reactions on natural silver in the 40-50 MeV energy range [PDF]
Nuclear Instruments and Methods B 436(2018)119-129, 2021 Natural silver targets have been irradiated by using a 50 MeV alpha-particle beam in order to measure the activation cross sections of radioisotopes in the 40-50 MeV energy range. Among the radio-products there are medically important isotopes such as $^{110m}$In and $^{111}$In.

Radioisotopes in Hematology. [PDF]
, 1956 The earliest therapeutic use of artificially produced radioactive isotopes in medicine was in the field of hematology, and dates back to the Summer of 1936 when radiophosphorus was administered to a patient with chronic lymphatic leukemia. This was twenty years ago when radioisotopes first became available for medical investigations from the 37-inch ...

Determination of gamma camera calibration factors for quantitation of therapeutic radioisotopes
EJNMMI Physics, 2018 BackgroundCamera calibration, which translates reconstructed count map into absolute activity map, is a prerequisite procedure for quantitative SPECT imaging. Both planar and tomographic scans using different phantom geometries have been proposed for the

A new production route of Gadolinium-148 for use in Radioisotope Thermoelectric Generators [PDF]
arXiv, 2021 The production of Gd-148 had challenges for available methods in the literature, such as its high cost and low production amount. Therefore, we recommended a new production route of Gd-148 on natural Sm and Eu targets via particle accelerators. For this aim, we calculated and simulated cross-section, activity, the yield of product, and integral yield ...

Radioisotopes and Nanomedicine [PDF]
, 2011 Nanomedicine, the medical application of nanotechnology, is poised to make a major impact on the diagnosis and treatment of many diseases. It is a relatively new branch of science that involves harnessing the unique properties of particles that are nanometers in scale (nanoparticles) for both diagnostic and therapeutic applications. Nanoparticles (NPs)
