Statutory guidance

High-activity sealed radioactive sources and orphan sources directive

Guidance to the Environment Agency



Applications to hold, accumulate or dispose of high-activity sealed sources (HASS) are made by a prospective user to the relevant environmental regulator under section 12 of the Environmental Permitting Regulations 2010 (EPR2010) in England and Wales. The Environment Agency then carries out a determination of the application in advance of either granting a permit, or withholding permission. The Environment Agency also has the power to vary permits, whether on application by the person holding such a permit or on its own volition.
