Information about radioactive substance sites
Find out about radioactive substances sites
What is a Radioactive Substances site?
The Environmental Permitting (England and Wales) Regulations 2010 ('the Regulations') were introduced on 6 April 2010, and were amended in 2011 by the Environmental Permitting (England and Wales) (Amendment) Regulations 2011.
You can find detailed guidance on the regulation of radioactive substance on Gov.uk.
Radioactive Substances sites are defined in Schedule 23 to the Regulations and lists radionuclides which are subject to the Regulations. This Schedule also defines the types of use of radionuclides that is covered by the Regulations and the safety standards that should be applied to the handling of these radionuclides. The Schedule was re-issued through the 2011 Amendment Regulations, and it is this version that must now be used.
There are three main categories of radioactive substances dependant on the form in which the radionuclides are used:
- Sealed sources - where the radioactive nuclide is in a solid form enclosed within a container
- Open sources - where the radioactive nuclide is a gas or in solution and is used as a liquid
- HASS - high activity sealed sources
Does your activity require an EPR radioactive substance permit?
Part 2 of the Schedule sets out who needs a permit. You will need a permit if you carry out one or more of the radioactive substances activities listed in the Schedule unless your substances are out of scope or exempt:
The list of activities includes:
- keeping or using radioactive material
- receiving, accumulating or disposing of radioactive waste
- keeping or using mobile radioactive apparatus

Completing the Application Forms
When making an application, you should always fill out three forms:
Form A (About you and your premises)
Form F (Charges and declarations)
And either B1, B2, B3, B4, B5, C2, C3, C4, D2, D3, E2, or E4 - depending on what type of application you are applying for.
Please note that forms B3 and C3 are for nuclear sites.
Regulatory Guidance Notes (RGNs)
The Radioactive Substances Regulation (RSR) Environmental Principles (REPs) provides a standardised framework for the assessments and judgements we make when regulating the use of radioactive substances. They provide guidance that helps underpin the decisions we make, including those about permitting and compliance where we regulate directly and where we are consultees or otherwise have influence.
- RGN RSR1 - Radioactive Substances Regulation - Environmental Principles
- RSR RGN3 provides an overview of the regulation of radioactive substances on non-nuclear sites
Further guidance covering the following topics can be found on the Environment Agency’s website:
- RSR principles of optimisation
- Radiological monitoring technical guidance note 2 - Environmental Radiological Monitoring
- Radiological monitoring technical guidance note 2 - Quick guide
- Criteria for setting limits on the discharges of radioactive waste from nuclear sites
- Principles for the Assessment of Prospective Public Doses arising from Authorised Discharges of Radioactive Waste to the Environment
How to comply
Guidance on how to comply with the main types of radioactive substances regulation (RSR) environmental permits is available on Gov.uk.
You can use guidance to help you understand:
- your permit
- the conditions we consider necessary to regulate your activity
- what you should do to comply with your permit

High Activity Sealed Sources (HASS)
If your permit requires you to submit High Activity Sealed Sources (HASS) reports, you will be sent the form and guidance when you receive your permit. Existing permit holders can request the form from us by emailing email@example.com.

You should consider how climate change could increase flood risk and so pollution risk. To help you assess your flood risk and measures you can take, you can read guidance on the Environment Agency’s website - 'Flood risks for small users of radioactive substances'
No practice involving exposures to radiation should be adopted unless it produces sufficient benefit to the exposed individuals or to society to offset the radiation detriment it causes (the ‘justification’ principle).
We can only issue a permit for a radioactive substances activity that relates to a ‘justified practice’ or work not subject to the requirement for justification. Decisions on whether a practice is justified are made by Government and further information can be found on the GOV.UK website.
