AbstractAbstract
[en] This work represents a comparative study of the radiothermoluminescence (R.T.L.) induced by 60Co gamma rays and 238Pu alpha-particles in three R.T.L. materials: lithium fluoride, alumina and dysprosium activated calcium sulphate. The T.L. glow curves induced by the two radiations are very similar. However, for the same absorbed dose, different sensitivity is seen to each form of irradiation. Measurements of the relative R.T.L. efficiency, epsilon, were made in the linear zone (dose<1Gy). These response differences are attributed to the manner in which the energies of the two radiations are distributed in the detection material. Theoretical determination of epsilon can be carried out from calculation of the spatial distribution of the ionization energy density around the α-particle track

Ce travail represente une etude comparative de la radiothermoluminescence (R.T.L.) induite par les rayons γ du 60Co et les particules α du 238Pu sur trois produits R.T.L.: le fluorure de lithium, l'alumine et le sulfate de calcium active au dysprosium. Les courbes de T.L. induites par les deux rayonnements ont des allures tres similaires. Cependant les deux radiations montrent, pour une meme dose absorbee, des sensibilites differentes. Des mesures de l'efficacite relative de R.T.L., epsilon, ont ete effectuees dans la zone lineaire (dose<1Gy). Ces differences de reponse sont attribuees a la maniere dont l'energie des deux rayonnements est distribuee dans le materiau detecteur. Une determination theorique epsilon peut etre faite a partir d'un calcul de la distribution spatiale de la densite d'energie d'ionisation autour de la trajectoire de la particule αOriginal Title
