Naturally Occurring Radioactive Materials (NORM)
We are responsible for regulating the keeping and use of radioactive substances and the accumulation and disposal of radioactive wastes. These pages describe the development of the UK strategy for managing wastes containing naturally occurring radioactive material (NORM).

These pages describe the development of the UK strategy for managing wastes containing naturally occurring radioactive material (NORM).
Naturally occurring radioactive materials exist in the earth’s crust as a result of the decay of heavy elements produced by cosmic processes. In their natural state they are not considered waste. NORM waste is produced when activities including mining and the processing of minerals and contaminated earth concentrate NORM. It is also produced as a result of maintenance and decommissioning of equipm
Radioactive waste advisers
There is a requirement under European law for people who keep or use radioactive material, or who accumulate or dispose of radioactive waste, to appoint advisers, known as ‘radiation protection experts’ to advise them on radiological protection.

Previous classification schemes
Before the introduction of the Water Framework Directive, SEPA had a number of classification schemes which we used to report the status of Scotland's water environment.

SEPA confirms Dalgety Bay remediation work is complete
SEPA is satisfied that the remediation work carried out by the Defence Infrastructure Organisation (DIO) and its contractor Balfour Beatty, alongside future monitoring plans and agreed maintenance of rock armour by Fife Council, means the public will be able to enjoy access again for the first time since 2011.
SEPA has been able to work with p
Modelling
Marine aquaculture modelling
Computer modelling is used as a guide to determining licensed discharge quantities of anti-parasitic chemicals and organic waste arising from marine fish-farm operations.
The modelling tools promoted by SEPA provide robust predictions in most cases, requiring relatively little site-specific information. Nevertheless, the quality of the model outputs is dependent upon g
Strategic Environmental Assessment
Strategic Environmental Assessment (SEA) is a systematic process for identifying, reporting, proposing mitigation measures and monitoring environmental effects of plans, programmes and strategies. It aims to ensure that environmental issues are taken into account at every stage in the preparation, implementation, monitoring and review of plans, programmes and strategies of a public nature.

Emergency response planning
In the event of an incident involving the release of radioactivity to the environment, it’s our role to assess the impacts of the incident and advise on clean-up.
You can report an incident involving radioactive material or radioactive waste by calling SEPA's 24 hour pollution hotline on 0800 807 060
The extent of our involvement in a radioactive incident depends on the nature and scale of the inc
