When do I report an incident to HSENI?
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (NI) 1997 (RIDDOR) require certain radiation-related events to be reported to HSENI, including:
- the malfunction of a radiation generator or its ancillary equipment – during industrial radiography and irradiation of food, or the processing of products by irradiation – causing it to fail to de-energise at the end of the intended exposure period
- the malfunction of equipment used in industrial radiography or gamma irradiation, causing a radioactive source to fail to return to its safe position by normal means at the end of the intended exposure period

Information on reporting incidents to HSENI
You must report certain incidents to HSENI under:
- The Ionising Radiations Regulations (Northern Ireland) 2017 (IRRNI17)
- The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR)
- IRR17
If any of the following incidents occur, you will need to email a report to HSENI:
- where you suspect or have been informed that an overexposure has occurred
- where an accident or other occurrence takes place which is likely to result in a person receiving an effective dose of ionising radiation greater than the following you must arrange a dose assessment and report the results:
- dose greater than 6mSv or an equivalent dose greater than 15mSv for the lens of an eye
- dose greater than 150mSv for the skin or the extremities
- where there has been a loss, theft or release of a certain quantity of radioactive material
You can find full details of the above incidents that need to be reported in the Approved Code of Practice and guidance (L21).

RIDDOR
If either of the following incidents occur, you will need to report them to HSE:
- the malfunction of a radiation generator or its ancillary equipment – during industrial radiography and irradiation of food, or the processing of products by irradiation – causing it to fail to de-energise at the end of the intended exposure period
- the malfunction of equipment used in industrial radiography or gamma irradiation, causing a radioactive source to fail to return to its safe position by normal means at the end of the intended exposure period
