“…Biological samples were kept at the liquid nitrogen temperature and then were taken for probe graphitization followed by AMS analysis. A simplified way of tissue probe graphitization was developed by our Laboratory of radiocarbon methods of analyses (LRMA), which is a joint laboratory between Novosibirsk State University and Institutes of Russian Academy of Sciences, and it was described earlier …”

“…Then, 14 C‐aerosol was obtained and tested on mice in low‐dose inhalation. To detect ultra‐low doses of 14 C in different organs, we used an accelerator mass spectrometer (AMS) with the simplified way of preliminary tissue probe graphitization . We have reported the results of investigation of the penetration of 225 ± 25‐nm particles, inhaled at low dose by mice, to different organs.…”

Experimental results of the second series of experiments on the penetration of monodisperse polymeric particles, inhaled at low dose by mice, to different organs using direct way of particle registration, based on the ultra‐sensitive accelerator mass spectrometer (AMS), are presented. Polystyrene (PS) beads, composed of radiocarbon‐labeled styrene, were produced for testing them as model organic aerosols. Mice inhaled 14C‐PS aerosol of 3·105 ultrafine particles per 1 cm3 for 30 minutes every day during 5 days. Long‐term investigation showed that PS ultrafine particles have been effectively accumulated in lungs with the maximum content in the fifth day of postexposure, and have also appeared in liver on the fifth day of exposure and in the brain on the 30th day of experiments. No particles have been detected in kidneys, spleen, and excrements. Thirty‐five millions of particles remained in the lungs after half a year of postexposure showing extremely slow removal of such particles from the organ.

“…Depth-age model based on AMS-technic was performed in Budker Institute of Nuclear Physics (Novosibirsk, Russia). Chemical pre-treatment and graphitization of samples were carried out in Laboratory of Radiocarbon Methods of Analysis at Novosibirsk State University using laboratory installation (Lysikov et al, 2018). Six sediment layers were dated.…”

This paper studies the formation of the sediment cover in Lake Gusinoye. For this purpose, we used high-resolution seismic data. Depression of Lake Gusinoye has a tectonic origin; however, there is no evidence of recent tectonic activity. Sediment thickness in Lake Gusinoye is less than 9 m, and its history is short (<35-45 ka). In addition, seismic stratigraphy records contain three contrasting episodes when the lake level dramatically decreased. It is very likely that there were also other shorter episodes of low-level stands. Thus, seismic structures of lakes Gusinoye and Kotokel have a strong resemblance, and it is most likely that their history began at the same time, ca. 40 ka BP.

In the course of studies conducted by IAET SB RAS in the Lower Ob in 2016–2019, the understanding of the conditions for settlement of the Paleolithic population in the north of Western Siberia was significantly supplemented. Dating of a series of paleontological finds was carried out at the "Accelerated mass spectrometer of the Budker Institute of Nucle- ar Physics of SB RAS". The dates obtained show the distribution of the main representatives of the Upper Pleistocene fauna of Subarctica: Mammuthus primigenius – 50,000–15,000 BP, Coelodonta antiquitatis – 43,000–38,000 BP and 27,000–25,000 BP, Rangifer tarandus, Equus ferus – 40,000–10,000 BP, Bison sp. – 50,000–40,000 BP, Ovibos moschatus – 41,000–32,000 BP.
