Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE DE FABRICATION D'UNE SOURCE RADIOACTIVE. SELON CE PROCEDE, ON DEPOSE SUR UN SUBSTRAT EN UN METAL SUSCEPTIBLE DE RESISTER A LA CORROSION PAR DES SOLUTIONS NITRIQUES, CHOISI DANS LE GROUPE COMPRENANT LE TITANE, LE ZIRCONIUM, UNE COUCHE MINCE ACTIVE D'UN RADIOELEMENT PAR MISE EN CONTACT D'UNE SOLUTION NITRIQUE DUDIT RADIOELEMENT AVEC LEDIT SUBSTRAT ET EVAPORATION A SEC DE LADITE SOLUTION, ON FAIT SUBIR AU SUBSTRAT AINSI REVETU UN TRAITEMENT THERMIQUE DE FACON A OBTENIR UNE COUCHE D'UN REVETEMENT INACTIF CONSTITUE D'UN OXYDE DU METAL CONSTITUANT LEDITSUBSTRAT, PUIS ON DEPOSE UN MATERIAU REFRACTAIRE PAR PULVERISATIONS CATHODIQUES. APPLICATION DES SOURCES RADIOACTIVES AINSI OBTENUES A LA REALISATION DE DETECTEURS D'INCENDIE, PARATONNERRES OU D'ELIMINATEURS D'ELECTRICITE STATIQUE.
