241Am is one of the most hazardous transuranic nuclides because of its long half-life, alpha- and gamma-emissions, chemical toxicity, and a strong tendency to deposit in human organs and tissues [4,5]. Since the 1940s, 241Am has been continuously released into the marine environment as a...
A re-determination of the half-life of the α-decay nuclide 243Am is reported using the relative activity method. Different synthetic mixtures were prepared by mixing solutions of isotopically pure 241Am and enriched 243Am isotopes, with 241Am/243Am α activity ratios in the range of 0.2–2....

In the present work, we tested the hypothesis of the existence of correlation in the random trajectories of alpha particles emitted from241Am source...

Considering the lower 0.7 g/cm3 density, the half-value layer of the scrap for 241Am is equal to 0.25 cm, which means that the photon fluence is attenuated by a factor 1043 at the truck sideboard. Thus, an unshielded 185 GBq 241Am source could pass undetected from the RPM system. If...
Concentrations of 239Pu, 240Pu, and 241Am, and atomic ratio of 240Pu/239Pu in freshly fallen snow on Mt. Zugspitze collected in 2014, 2015 and 2016 were determined by accelerator mass spectrometry (AMS). For the sub-femtogram (10−15 g) - level of Pu a
