provisions made for protection against health hazards. The plant is made entirely of glass, the safe thickness of which can be calculated. Details are given of the vacuum system employed. Special manipulations described in the article cover the production and purification of tritium, tritiated water preparation, the preparation of tritium-zirconium targets, and the purification of krypton-8 5 and xenon-133
摘要 描述了放射性同位素气体,特别是氚、
氪 8 5 和
氙 I33 的特性,并给出了对预期放射性的估计。AERE Harwell 中可用于处理这些气体的设备进行了详细描述,并特别参考了为防止健康危害而制定的规定。植物完全由
玻璃制成,其安全厚度可以计算。详细介绍了所采用的真空系统。文章中描述的特殊操作包括氚的生产和提纯、氚化
水的制备、氚-
锆靶的制备以及
氪 8 5 和
氙 133 的提纯。除了用作研究工具外,这三种核素也越来越多地用于工业。
