définition de 크립톤-81m dans le dictionnaire coréen
Krypton-81m 81mKr 12 / isotope radioactif du krypton, numéro atomique 35, numéro de masse 81, 81) Les isomères nucléaires de Kr. La transition métaplasique nucléaire (IT) passe à 81Kr (demi-vie 2.1X105 ans). Une demi-vie de 13 secondes, et un rayon gamma (190 keV-100%). Il est fourni sous la forme d'un générateur de 81 mKr adsorbé sur une colonne de résine échangeuse de cations avec un radionucléide parent 81Rb (demi-vie 4,7 heures) et extrait en utilisant de l'air ou de l'oxygène dans un état non chaud ou sec pendant l'utilisation. 크립톤-81m 81mKr 12/크립톤의 방사성동위원소, 원자번호 35, 질량수 81, 81) Kr의 핵이성체(核異性體). 핵이성체전이(核異形體轉移) (IT)에 의해 81Kr(반감기2.1X105년)로 변한다. 반감기 13초, γ선(190keV-100%)을 방사한다. 어버이핵종 81Rb(반감기 4.7시간)를 양이온교환수지칼럼에 흡착시킨 81mKr제네레이터로서 공급되며, 사용시에 비(非)이 온수, 혹은 건조상태에서 공기 또는 산소에 의해 추출해서 사용한다.
