Salting out of americium-241 in the sorption process using a solid-phase extractant based on TODGA

Глобальная ядерная безопасность, 2023
Today, the «Proryv» project is developing effective methods of reprocessing irradiated nuclear fuel (SNF) to return long-lived radionuclides to the fuel cycle to close it.

Uptake of Radionuclides by Bryophytes in the Chornobyl Exclusion Zone

Toxics, 2023
The “Chernobyl nuclear disaster” released huge amounts of radionuclides, which are still detectable in plants and sediments today. Bryophytes (mosses) are primitive land plants lacking roots and protective cuticles and therefore readily accumulate ...

Rapid determination of gross alpha/beta activity in milk using liquid scintilation counter technique [PDF]

Nuclear Technology and Radiation Protection, 2016
Rapid determination of gross alpha and beta emitters in milk by liquid scintillation counter is discussed. This method is based on direct addition of different types of milk into scintillation cocktail and therefore it is very promising for fast

Flowsheets for the Validation of the Reference AmSEL System [PDF]

EPJ Web of Conferences
Recycling americium (Am) from spent nuclear fuels is an important option considered for the future nuclear fuel cycle as americium is the main contributor to the long-term radiotoxicity and heat power of the ultimate waste.

Formation of Complexes of f-Elements with Electron-Withdrawing N-Heterocyclic Diamides: Extraction and Solution Photophysics

Metals, 2023
To examine the scope of the abnormal aryl strengthening effect (an increase in the extraction of metal ions when an aromatic substituent is introduced into the amide group) on f-metal extraction, a series of tetradentate diamide-type extragents bearing ...

The Isotopes of Americium [PDF]

Physical Review, 1950
Three new americium activities (Am{sup 238}?, Am{sup 243}, and Am{sup 244?}, the latter two formed by n,{gamma} reactions) are described and some additional information is given on previously reported americium isotopes.
