MSP demands answer over clean up plans.
The UK Defence Secretary is being urged to clarify when the MOD will accept responsibility for radioactive contamination at Dalgety Bay.
Last month, a Comare report said contamination on the foreshore posed a potential risk to public health and could get worse unless action is taken.
Mid Scotland and Fife MSP Annabel Ewing has written to Philip Hammond.
In a statement, the UK Government says it is committed to making sure the local community at Dalgety Bay receives the best possible advice on the radiation leak.
