Abstract: (french)
De nos jours, les problèmes de la protection des travailleurs contre les dangers des rayonnements ionisants sont moins maîtrisés dans nos pays africains.Cependant, il est utile d’évaluer le niveau des risques d’expositions aux rayonnements ionisants des personnes travaillants dans des zones minières artisanales ; par la poussière émanant de ces zones minières pouvant contenir des éléments radioactifs naturels en son sein, d’origines tellurique ; et Il se pose par conséquent un problème de radioprotection. Pour bien faire notre étude, nous avons commencé par la prise des mesures d’ambiance de la radioactivité sur tout le site de Twilizembe et sur les cinq remblais des minerais de cobalt entreposés sur ce dernier, puis nous avons échantillonné sur ces remblais pour effectuer des analyses radiochimiques en vue d’évaluer le niveau de radioprotection des personnes travaillant sur ce site en s’appuyant sur la théorie des phénomènes physiques de désintégrations radioactives se passant dans différentes filiations radioactives (famille radioactive naturelle). Partant des résultats obtenus nous remarquons que les valeurs de concentrations en uranium sont trop faibles, mais peuvent avoir de l’impact néfaste sur les personnes dans les futurs (pour les cas des effets stochastiques) et d’où la nécessité d’évaluer les autres aspects d’expositions pour être très précis et donner une conclusion définitive a ce travail.
