This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically\n                    <jats:sup>222<\/jats:sup>\n                    Rn,\n                    <jats:sup>238<\/jats:sup>\n                    U,\n                    <jats:sup>232<\/jats:sup>\n                    Th, and\n                    <jats:sup>40<\/jats:sup>\n                    K, in cement and gypsum samples from regional production facilities. Radionuclide activity concentrations were measured using alpha counting techniques and gamma spectrometry. The air concentrations of radon gas ranged from 76.14 to 285.98\u2009Bq\/m\n                    <jats:sup>3<\/jats:sup>\n                    , with an average of 169.42\u2009Bq\/m\n                    <jats:sup>3<\/jats:sup>\n                    . Although the activity concentrations of gamma\u2010emitting radionuclides were within internationally acceptable limits, they still contributed to cumulative radiation exposure. The risk of lung cancer was estimated for workers with occupational exposure durations of 5, 10, 20, and 30\u2009years, considering both alpha particle exhalation and gamma radiation exposure. The results indicated an average lung cancer risk of 0.03% for individual workers, with a progressive increase corresponding to the duration of employment. For long\u2010term exposure (30\u2009years), this risk increased to between 0.029% and 0.04% per individual. While most radiological parameters fall within Health Canada Guidelines, the cumulative effects of radiation exposure suggest the need for strict radiation protection protocols. This research establishes essential baseline data for occupational health standards in the construction materials industry of Iraqi Kurdistan and highlights the importance of continuous radiological monitoring and safety measures for workers in cement and gypsum production facilities.\n                  <\/jats:p>","DOI":"10.1002\/tox.70192","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T10:53:36Z","timestamp":1787828016000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Integrated Alpha\u2013Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6655-7077","authenticated-orcid":false,"given":"Adil M.","family":"Hussien","sequence":"first","affiliation":[{"name":"Department of Physics College of Science, University of Sulaimani  Sulaymaniyah Kurdistan Region Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0968-6617","authenticated-orcid":false,"given":"Kardo O.","family":"Mamand","sequence":"additional","affiliation":[{"name":"Department of Physics College of Science, University of Sulaimani  Sulaymaniyah Kurdistan Region Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5585-3260","authenticated-orcid":false,"given":"Hiwa M.","family":"Qadir","sequence":"additional","affiliation":[{"name":"Department of Physics College of Science, University of Raparin  Sulaymaniyah Kurdistan Region Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0450-3919","authenticated-orcid":false,"given":"Berun N.","family":"Ghafoor","sequence":"additional","affiliation":[{"name":"Department of Physics College of Education, University of Sulaimani  Sulaymaniyah Kurdistan Region Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4822-1497","authenticated-orcid":false,"given":"Goran H.","family":"Mohammad","sequence":"additional","affiliation":[{"name":"Centre for Translational Medicine and Therapeutics, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London  London UK"},{"name":"Chemistry Department College of Science, University of Sulaimani  Sulaymaniyah Kurdistan Region Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/B978-0-443-26643-0.00003-0","volume-title":"New Perspectives in Indoor Air Quality","author":"Carriera F.","year":"2026"},{"issue":"1","key":"e_1_2_10_3_1","doi-asserted-by":"crossref","first-page":"549","DOI":"10.1007\/s11600-024-01480-7","article-title":"Radiological Hazard Assessment due to Natural Radioactivity Content in Cement Material Used in Iraqi Kurdistan Region","volume":"73","author":"Qadr H.
