LA-1721，第4版，《放射化学程序集》的修订，反映了洛斯阿拉莫斯国家实验室同位素和核化学部门的两个小组的活动：INC-11，核和放射化学；c -7，同位素地球化学。程序分为五类：1 .从铀、裂变产物溶液和核碎片中分离放射性核素；2。辐照产物与靶物的分离3。质谱分析用样品的制备四、解散程序；五、地球化学程序。除了一个例外，第一类程序是根据元素周期表中元素的位置排序的，代表元素（A族）上有单独的部分；d-过渡元（B群和过渡三联）；以及镧系元素（稀土）和锕系元素（4f和5f过渡元素）。IIIB族的成员——钪、钇和镧——被包括在镧系元素中，它们在化学上非常相似，并且在自然界中与它们一起存在。处理从辐照目标中分离产物的程序按目标元件排列。
This revision of LA-1721, 4th Ed., Collected Radiochemical Procedures, reflects the activities of two groups in the Isotope and Nuclear Chemistry Division of the Los Alamos National Laboratory: INC-11, Nuclear and radiochemistry; and INC-7, Isotope Geochemistry. The procedures fall into five categories: I. Separation of Radionuclides from Uranium, Fission-Product Solutions, and Nuclear Debris; II. Separation of Products from Irradiated Targets; III. Preparation of Samples for Mass Spectrometric Analysis; IV. Dissolution Procedures; and V. Geochemical Procedures. With one exception, the first category of procedures is ordered by the positions of the elements in the Periodic Table, with separate parts on the Representative Elements (the A groups); the d-Transition Elements (the B groups and the Transition Triads); and the Lanthanides (Rare Earths) and Actinides (the 4f- and 5f-Transition Elements). The members of Group IIIB-- scandium, yttrium, and lanthanum--are included with the lanthanides, elements they resemble closely in chemistry and with which they occur in nature. The procedures dealing with the isolation of products from irradiated targets are arranged by target element.
