Overview Guide: Know all about Radioactivity Analysis in Drinking Water as per regulatory guidelines

European council's new directives on gross a/ß-measurement in drinking water have been the focus of many laboratories throughout Europe and another part of the worlds. The change in requirements such as sampling rate, detection limits, and more which have forced many labs to upgrade instrumentation and adjust their previous methods. This guide has been developed to do just that and provides a fast, gross a/ß–screening method as a reference for those looking to establish a new method. Should you find yourself needing additional support, PerkinElmer can also provide online or on-site training to help you set up new methods on PerkinElmer liquid scintillation counters.
