All mean values of the health risk indices (Ra_eq, D_ex, D_in, AGDE, and AED) were below the limits recommended by ICRP/UNSCEAR. This result indicates moderate exposure for the population, with no significant short-term impact, but should be monitored in the event of prolonged accumulation. The results of this original study provide new information on the radioactivity of building materials in Côte d'Ivoire and worldwide.]]> Brigui Olkalé Jean-Claude, Gogon Bogbé Douo Louis Huberson, Konaté Issa, El Banni Fadi, Georges Alain Monnehan, Aka Antonin Koua, KOUASSI Gofri Marie Chantal 2026-02-10 Science and Education Publishing 2026-02-10 1 10 1 5 10.12691/pmc-10-1-1
