Ionising radiation notifications
When do I need to notify HSE?
You will need to notify or provide information to HSE:
What do I notify about under IRR99?
Starting work with ionising radiation for the first time
If you intend to start work with ionising radiation for the first time you will normally need to let HSE know at least 28 days before you start work unless:
- the notification is in relation to Radon on naturally occurring radioactive (NORM) in which case notification should be made forthwith after work begins
- you are a nursing home receiving a radioactive patient for the first time, in which case notification should be as soon as practicable.
- Note – this form is for the notification of work with ionising radiation only. Please ensure that you retain the automated acknowledgement email you receive as this is confirmation that you have informed HSE
- If you are unsure whether HSE has been previously notified of your work with Ionising Radiation please complete an IRR6 notification form as you will then receive an automated acknowledgement email.
This is a requirement of Regulation 6 of the Ionising Radiations Regulations 1999 (IRR99). Employers working with ionising radiation exclusively on Nuclear sites should notify the Office of Nuclear Regulation (ONR).
To notify HSE of your intention to start work use form IRR6 - Notification of ionising radiation activities for which you will need to provide the following information:
- your name and address
- a contact telephone or fax number
- your email address (if you are notifying online)
- the address of the premises from where the work activity is to be carried out and a telephone / fax number or email address at the premises
- the nature of the business and which one of the following categories your use of ionising radiation falls into:
- sealed source
- unsealed radioactive substance
- electrical equipment (for example, X-ray equipment)
- an atmosphere containing the short-lived daughters of radon-222
- whether any source is to be used at premises other than the address provided
- dates of notification (when the information is sent) and the intended commencement of the work activity
Some work is exempt from notification; details of the work that you do not need to tell HSE about can be found here (see Work not required to be notified).
Making changes to an existing notification under Regulation 6
Radiation employers need to inform HSE when the details of a previous notification are no longer correct, such as when:
- the employer’s details or those of their premises change;
- the source category changes, for example, if an original notification covered the use of an X-ray set but you intend to start using radioactive substances;
- the source is to be used at a different premises, not included in the previous notification; and
- you are stopping work with ionising radiation and vacating all or part of the premises.
To make changes to a previous notification, or if you are unsure that HSE has been notified in the past, for example due to change of ownership - please use form IRR6 - Notification of ionising radiation activities.
Other notifications required under IRR99
- Industrial site radiography, with the exception of work on Nuclear sites or such work by or on behalf of MoD, is subject to an additional requirement to notify HSE 7 days prior to each instance of work. You need to notify HSE of site radiography (notification of intention to carry out site radiography), through HSE’s Ionising Radiations Notification Web Community (IRNWC). To do this you will need to register to join the IRNWC, please read registration guidance. If you have already done so, go to IRNWC. If you have any problems accessing these sites please telephone 0151 951 5856.
- Where a radiation employer suspects or has been informed that an overexposure has occurred (see regulation 25).
- A loss, theft or release of a certain quantity of radioactive material has occurred (see regulation 30).
- Where an employer suspects or has been informed that a person, while undergoing a medical exposure, was exposed to ionising radiation to a much greater extent than intended, as the result of a malfunction or defect in radiation equipment (see regulation 32(6)).
- If you need to notify HSE or gain authorisation for any of these reasons please e-mail: firstname.lastname@example.org.
What information must I provide under REPPIR?
The Radiation Emergency Preparedness and Public Information Regulations 2001 (REPPIR) requires that operators of premises with radioactive substances in excess of the threshold quantities specified in schedule 2 of REPPIR, unless exempted by regulation 3(4), carry out a risk assessment (termed a Hazard Identification and Risk Evaluation, or ‘HIRE’) and send a report of the assessment to HSE. Operators must do this twelve months before the work is to be undertaken – unless a shorter period is agreed beforehand by HSE.
The HIRE’s submitted should contain sufficient information and appropriate cross references for HSE to confirm the outcome of the assessments. The HIRE should be sufficient to demonstrate that:
- all hazards arising from that work with the potential to cause a radiation accident have been identified; and
- the nature and magnitude of the risks to employers and other persons arising from those hazards have been evaluated.
Where there is a significant change to the amount of radioactive material, the conduct of the work or to the premises, a further assessment must be made and a revised HIRE submitted to HSE.
In any case the HIRE should be reviewed every three years, and updated if the work has changed in any way, or if there have not been any changes of circumstances then a declaration signed to that effect. The revised HIRE or Declaration must be submitted to HSE.
If any of the above applies to you then please submit a hire report- REPPIR1 - Provision of an Assessment Report.
What do I notify about under RIDDOR?
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) require certain radiation-related events to be reported to HSE, 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.
For RIDDOR reporting procedures, see RIDDOR website.
Other ways to notify HSE
Radiation incident reports (required under Ionising Radiations Regulation 25, 30 or 32) and HIRE assessment reports (required under Radiation Emergency Preparedness and Public Information Regulations) should be emailed to : email@example.com. Alternatively, if your application and any supporting documentation cannot be sent by email, please inform us by email and we will make arrangements for a postal application.
Site radiography notifications should only be sent through the HSE Web Communities system. However, if there are problems with this system, please contact the radiation notifications administrator on tel. no. (0151) 951 5856.
