Signs warning of radioactive contamination risks should be set up at a Fife beach, a watchdog has said.
The study examined whether warning signs should be displayed
The Scottish Environment Protection Agency (Sepa) made the recommendations after a study of the foreshore at Dalgety Bay.
The agency spent £50,000 examining the extent and implications of possible contamination from WWII aircraft parts.
NHS Fife said the health risks were low but advised anyone touching material from the beach to wash their hands.
Sepa has been discovering more radioactive items at Dalgety Bay than at Sandside Beach, near the Dounreay nuclear plant in Caithness.
More than 90 radioactive items were found at Dalgety Bay during monitoring of the area last year.
This compared with more than 50 particles discovered during monitoring of Sandside Beach.
However, Sepa said a different kind of radioactivity had been found in Fife.
The study aimed to assess the chances of people swallowing or breathing in the particles and whether warning signs should be displayed.
A spokesman said: "This is a precautionary measure based on a draft screening assessment of the contamination.
"This recommendation will be reviewed following the completion of the screening report.
"Sepa considers that signage would allow the public to be informed of the potential hazard on the beach."
In addition to public signs, it has also been recommended that two further stages of work be undertaken to identify and quantify the source of the
contamination, and to investigate how it can be remedied.
The radioactivity is believed to have come from the luminous dials of wartime aircraft, which are thought to have been dumped there after the war.
