Environmental guidance for your business in Northern Ireland & Scotland
Radioactive substances include radioactive material and radioactive waste. In Northern Ireland different legal controls apply to handling radioactive material and dealing with radioactive waste. In Scotland radioactive materials and radioactive waste are covered by the same regulations.
Radioactive material includes substances or articles that are radioactive, or have become radioactive through non-natural processes, for example at a nuclear reactor.
The regulations will not apply to your business if the concentration of radioactivity in the materials that you keep or use is below the levels set out in:
Northern Ireland: Schedule 1 of the Radioactive Substances Act 1993.
This applies both when the materials are naturally occurring radioactive materials (NORM) and when they have been man made.
If the concentration of radioactivity in the materials you keep or use is below the levels set out in the regulations, then you are “out of scope” of the regulations and you do not need to contact your environmental regulator. You should still make sure you comply with your Duty of Care when dealing with wastes.
If you keep or use radioactive materials that are above the levels set out in Schedules listed above, or they are not naturally occurring radioactive materials, you will need:
Radioactive materials are used by many organisations. For example, hospitals, research organisations, radiographers and process industries use radioactive materials for:
Different types of radioactive material, including open and sealed radioactive sources, are used for different activities.
Open radioactive sources are radioactive materials that you can easily divide, disperse or dilute. They can be in a liquid, gaseous or sometimes solid form. Open sources include radioactive laboratory chemicals and radiopharmaceuticals.
Open radioactive sources can potentially contaminate other material through leakage or leaching. You must store all open radioactive sources securely.
Sealed radioactive sources have a structure which prevents radioactive material from leaking during normal use. If you use sealed sources incorrectly you could cause radioactive contamination.
Mobile radioactive apparatus includes equipment, appliances or other things that are portable and classed as radioactive material. They may be used for:
Mobile radioactive apparatus may contain sealed or open radioactive sources.
In Northern Ireland you must have a certificate of registration if you keep or use mobile radioactive apparatus, unless you are covered by an exemption.
In Scotland you must have the correct authorisation if you manage mobile radioactive apparatus.
Radioactive waste includes certain substances which would be radioactive material if they were not waste, or substances which have been contaminated by radioactive material or other radioactive waste. It can be in a solid, liquid or gaseous form.
Radioactive waste may include contaminated clothing that needs to be disposed of, laboratory wastes from the use of open radioactive material or a sealed source which is scrap.
There are four types of radioactive waste:
Radioactive substances users at non-nuclear sites are only likely to produce very low-level or low-level radioactive waste.
What are radioactive substances?
My Year at NetRegs, A reflection on my time as an intern with the NetRegs team at SEPA. An overview of all the activities and projects I had the opportunity to participate in during my Bright Green Environmental Placement.
A day with Hydrology, SEPA's hydrometry unit is responsible for around 400 gauging stations and 350 rainfall monitoring sites. River gauging stations are important as they allow river levels to be monitored so flood events can be predicted and flood warnings sent out.
