In recent years, radium has attracted considerable attention primarily because of the rapid increase in unconventional (fracking) drilling technology in the United States and around the world. One of the major radionuclides of interest in unconventional drilling wastes is radium isotopes (²²⁴Ra, ²²⁶Ra, ²²⁸Ra). To access long-term risks associated with radium isotopes entering into the environment, accurate measurements of radium isotopes in environmental and biological samples are crucial. This article reviews many aspects of radium chemistry, which includes recent developments in radiochemical separations methods, advancements in analytical techniques followed by a more detailed discussion on the recent trends in radium determination.

近年来，镭引起了相当大的关注，这主要是由于美国和世界范围内非常规（压裂）钻探技术的迅速增长。非常规钻井废料中感兴趣的主要放射性核素之一是镭同位素（²²⁴ Ra，²²⁶ Ra，²²⁸ Ra）。为了获得与镭同位素进入环境有关的长期风险，准确测量环境和生物样品中的镭同位素至关重要。本文回顾了镭化学的许多方面，包括放射化学分离方法的最新发展，分析技术的发展，然后对镭测定的最新趋势进行了更详细的讨论。
