Notices warning of radioactivity have been put up on a beach in Fife after the discovery of dozens of contaminated items.
Traces of radiation have been turning up along the foreshore
The move follows foreshore monitoring at Dalgety Bay on the Firth of Forth.
The Scottish Environment Protection Agency (Sepa) believes the risk is low but warned people to take precautions.
The contamination is believed to have come from the luminous dials of wartime aircraft thought to have been dumped there after World War II.
Sepa has been carrying out a risk assessment at the bay and now wants a detailed investigation to be carried out.
It concluded warning signs should be erected at the beach, which has been carried out by Fife Council.
More than 90 radioactive items were discovered during monitoring.
The notices advise that radioactive material has been found on the beach, that people should wash their hands after handling any material and that nothing should be removed, including fish or shellfish.
However, the risks from coming into contact with radioactive material were said to be low, with the likely effect being a skin burn.
More radioactive items have been found at Dalgety Bay than at Sandside Beach, near the Dounreay nuclear plant in Caithness.
