Uranium Isotope Characterization in Volcanic Deposits in a High Natural Background Radiation Area, Mamuju, Indonesia

Geosciences, 2023
Mamuju is an area of high natural radiation in Indonesia with high natural radiation levels (average 613 nSv h−1). Mamuju is anomalous due to its high average 238U and 232Th concentrations of 22,882 and 33,549 Bq kg−1, respectively, in laterite and rock.

Investigation of the Segregation of Radiocesium from Contaminated Aqueous Waste Using AMP-PAN Extraction Chromatography

Energies, 2023
Removing the hazardous and unstable radioactive isotopes has been considered an arduous task, though they are in minimal concentrations. Cesium-137 (137Cs+) is a primary fission product produced by nuclear processes.

Recovery of ¹⁷⁷Lu from Irradiated HfO₂ Targets for Nuclear Medicine Purposes

Molecules, 2022
A new method of production of one of the most widely used isotopes in nuclear medicine, 177Lu, with high chemical purity was developed; this method includes irradiation of the HfO2 target with bremsstrahlung photons.

On the interference of 210Pb in the determination of 90Sr using a strontium specific resin [PDF]

Nuclear Technology and Radiation Protection, 2013
We investigated the interference of radiolead in the isolation of radiostrontium using a strontium-specific resin by means of 85Sr and 212Pb radiotracers. The resin was found to be almost equally specific for lead ions as well.

A modified method to eliminate 210Bi interference in the analysis of 90Sr by extractive chromatography

He jishu, 2022
Background210Bi is one of the most important interferences in the analysis of 90Sr by extractive chromatography. It is verified by the leaching curve that bismuth and yttrium are completely adsorbed on the chromatographic column in the bis(2-ethylhexyl ...

Rapid Elution of ²²⁶Th from a Two-Column ²³⁰U/²²⁶Th Generator with Diluted and Buffer Solutions

Molecules, 2023
A radionuclide generator of the short-lived alpha emitter 226Th was proposed. An original scheme consisting of two in-series chromatographic columns was developed for rapidly producing a neutral citric-buffered eluate of high purity 226Th.

A Radionuclide Generator of High-Purity Bi-213 for Instant Labeling

Pharmaceutics, 2021
A new two-column 225Ac/213Bi generator was developed specifically for using 225Ac containing an impurity of long lived 227Ac. The parent 225Ac was retained on the first Actinide Resin column, while 213Bi was accumulated on the second column filled with ...
