An application was made under the Justification of Practices Involving Ionising Radiation Regulations 2004 for a determination as to whether the process of using a radioactive source in a smart gas meter was an existing class or type of practice. This document briefly describes the regulatory background and outlines the application and the process for considering it.
The document then sets out the reasons for the Secretary of State for Energy and Climate Change’s determination, as Justifying Authority, that this use of a radioactive source is not justified as an existing class or type of practice.
