The identification of the EPR spectra of the body and shell parts of the control and irradiated grape snails separately showed that more iron oxide magnetic nanoparticles are generated in the body part of the grape snail compared to the shells. A linear increase in free radical signals (g = 2.0023) in the body and shell parts of grape snails, and a non-monotonic change in the broad EPR signal (g = 2.32) characterizing iron oxide magnetic nanoparticles was determined depending on the dose of ionizing gamma radiation. Additionally, the obtained results showed that grape snails can be used as bioindicators for examining the ecological state of the environment. At the same time, the radionuclide composition of the body and shell parts of the grape snails and their specific activities were determined by CANBERRA gamma spectroscopy. The FTIR spectra of mucin, a liquid secreted by snails, were recorded.<\/jats:p>","DOI":"10.3390\/molecules28041872","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T04:01:52Z","timestamp":1676520112000},"page":"1872","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Electron Paramagnetic Resonance Studies of Irradiated Grape Snails (Helix pomatia) and Investigation of Biophysical Parameters"],"prefix":"10.3390","volume":"28","author":[{"given":"Aygun","family":"Nasibova","sequence":"first","affiliation":[{"name":"Institute of Radiation Problems, Ministry of Science and Education Republic of Azerbaijan, AZ1143 Baku, Azerbaijan"},{"name":"Department of Biophysics and Biochemistry, Baku State University, AZ1148 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rovshan","family":"Khalilov","sequence":"additional","affiliation":[{"name":"Institute of Radiation Problems, Ministry of Science and Education Republic of Azerbaijan, AZ1143 Baku, Azerbaijan"},{"name":"Department of Biophysics and Biochemistry, Baku State University, AZ1148 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahammad","family":"Bayramov","sequence":"additional","affiliation":[{"name":"Institute of Radiation Problems, Ministry of Science and Education Republic of Azerbaijan, AZ1143 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u0130slam","family":"Mustafayev","sequence":"additional","affiliation":[{"name":"Institute of Radiation Problems, Ministry of Science and Education Republic of Azerbaijan, AZ1143 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aziz","family":"Eftekhari","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Science, Ege University, Izmir 35040, Turkey"},{"name":"Institute of Molecular Biology & Biotechnologies, Ministry of Science and Education Republic of Azerbaijan, 11 Izzat Nabiyev, AZ1073 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mirheydar","family":"Abbasov","sequence":"additional","affiliation":[{"name":"Institute of Catalysis and Inorganic Chemistry, Ministry of Science and Education Republic of Azerbaijan, AZ1143 Baku, Azerbaijan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4782-1602","authenticated-orcid":false,"given":"Taras","family":"Kavetskyy","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Drohobych Ivan Franko State Pedagogical University, 82100 Drohobych, Ukraine"},{"name":"Department of Materials Engineering, The John Paul II Catholic University of Lublin, 20-950 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gvozden","family":"Rosi\u0107","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Medical Sciences, University of Kragujevac, 34000 Kragujevac, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8264-2477","authenticated-orcid":false,"given":"Dragica","family":"Selakovic","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Medical Sciences, University of Kragujevac, 34000 Kragujevac, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","first-page":"382","article-title":"Response of soybean plants to gamma radiation: Biochemical analyses and expression patterns of trichome development","volume":"7","author":"Chelik","year":"2014","journal-title":"Plant Omics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1016\/j.jenvrad.2019.02.001","article-title":"Effect of ionizing radiation on physiological and molecular processes in plants","volume":"202","author":"Gudkov","year":"2019","journal-title":"J.
