Land is defined as radioactive when a person could be harmed by spending time on land where radioactivity is present.
Some types of contaminated land are classed as special sites. This includes land that:
- seriously affects drinking waters, surface waters (for example lakes and rivers) and important groundwater sources
- has been, or is being, used for certain industrial activities, such as oil refining or making explosives
- is being or has been regulated using a permit issued under the integrated pollution control or pollution prevention and control regimes
- has been used to get rid of waste acid tars
- is owned or occupied by the Ministry of Defence
- is contaminated by radioactivity
- is a nuclear site
The Environment Agency has technical guidance on special sites.
Once a local council has decided that an area is a special site, it is regulated by the Scottish Environment Protection Agency (SEPA).
