THOUSANDS of Portland residents are to be given information packs telling them what to do in a nuclear emergency.
The Ministry of Defence is taking a range of measures in response to the reinstatement of visits by Royal Navy nuclear-powered submarines to Portland Port.
Tomorrow it will start the distribution of the booklets to around 4,300 people living within a 2km radius of the Portland berth.
The guides will inform them of the relevant hazards and contingency plans in the very unlikely' event of an accident involving a nuclear-powered vessel.
The MoD teamed up with Portland Port, Dorset County Council and Weymouth and Portland Borough Council to draw up the emergency response plans in accordance with the Radiation (Emergency Prepared-ness and Public Information) Regulations 2001.
The contingency plan will be similar to one already in existence for Southampton that covers areas such as media warning strategies, inter-agency response and the distribution of potassium iodate tablets (PITs).
The Southampton plan, Soton-Safe, also gives residents advice on what to do if the worst should happen. It says: 'Those residents living within an area up to 2km downwind from the berth will be advised to take shelter indoors and take the tablets if/when directed. Those working or in transit within the 2km zone downwind should self evacuate the area'.
