Traitement du cancer<\/h3>\n

Les isotopes radioactifs peuvent \u00eatre transform\u00e9s en m\u00e9dicaments. Une fois inject\u00e9 dans un patient, le m\u00e9dicament s\u2019accumule dans la partie du corps o\u00f9 se trouve une tumeur. Lorsque les isotopes se d\u00e9sint\u00e8grent et lib\u00e8rent de l\u2019\u00e9nergie, cette \u00e9nergie d\u00e9truit la tumeur.<\/p>\n
