Details

The Environmental Permitting (England and Wales) Regulations 2016, Part 5 Schedule 23, set out the requirements for the control of high-activity sealed sources (HASS) and other sealed sources. This includes record keeping by source holders and competent authorities. 

Operators are required by their permit to make and maintain HASS records and report those changes to the Environment Agency using this form when they:

• apply for and receive a new permit for HASS sources
• change the equipment in which a HASS source is kept
• intend to keep, use or store a HASS source permitted for mobile use at another location for longer than 3 months
• receive a HASS source
• transfer a HASS source
• lose, have stolen or recover a HASS source
• need to correct information they have reported before
• need to tell the Environment Agency when a source has decayed below a HASS threshold
• submit a confirmatory report (due every 5 years)

If your permit requires you to submit HASS records, you should use this electronic report form.

To submit your HASS record electronically, use the secure HASS record transfer link. 

The link will take you to an Environment Agency approved page for secure transmission of your HASS record using a file transfer system called Quatrix. Complete the short form and follow the instructions to upload your HASS record.

All information about sealed radioactive sources, including waste sealed sources, is subject to national security restrictions. This includes HASS records. The Environment Agency will not put HASS records or related information on the public register.

Contact the International Waste Shipments Team at iws_rsr@environment-agency.gov.uk if:

• you have any questions about electronic submission of HASS records
• you wish to send a printed copy of your HASS record securely in the post
