Radioactive monitoring of beaches on the Scottish side of the Solway Firth is to be stepped up.
There is currently no evidence of particles moving into the firth
The move followed an increase in the number of radioactive particles being found on the Cumbrian shore.
They were identified as having come from the Sellafield nuclear plant and concerns have been raised they could be carried over by the tide.
The Scottish Environment Protection Agency said there was no evidence of particles moving into the firth.
However spokesman Paul Dale said there was a risk that it could happen, adding that the agency would commission a programme of monitoring beaches on the Scottish coast to see if any contamination was present.
Sepa was alerted by its English counterpart about an increase in the number of radioactive particles on beaches in North Cumbria.
Dumfries and Galloway's director of public health Derek Cox said current evidence suggested that the risk to human health was exceedingly small.
He said there was no need to reduce access to, or use of, any of the region's beaches.
The Scottish Food Standards Agency will also carry out a risk assessment.
