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 (Ra, Ra, Ra). 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，镭受到了相当大的关注，主要是因为美国和世界各地非常规（水力压裂）钻井技术的快速发展。非常规钻井废物中感兴趣的主要放射性核素之一是镭同位素（Ra、Ra、Ra）。为了了解与镭同位素进入环境相关的长期风险，对环境和生物样本中镭同位素进行准确测量至关重要。本文综述了镭化学的许多方面，包括放射化学分离方法的最新进展，分析技术的进步，以及对镭测定的最新趋势的更详细讨论。
