The dose imparted, as well as doses to the thyroid, breast, lung, bone-marrow, ovary and testis have been calculated for many types of radiographic examinations. Collective doses have been calculated as well as risk

On exprime dans ce travail des conditions ntcessaires et suffkantes pour que mM (resp. T+mM) soit A-entier, lorsque M est un point A-entier, T un point de 2-torsion sur Q de la courbe, et m un entier rationnel. Ces conditions portent sur les polynhmes 4, et I), qui permettent d'exprimer l'abscisse de mM. Nous donnons des exemples d'application qui montrent que ces conditions peuvent &tre utiliskes dans la pratique. Si la courbe est de rang 1 sur Q avec Cventuellement des points de 2-torsion rationnels, on peut espkrer trouver tous les points A-entiers de la courbe.
