The Civil Defence organisation has a nucleur radiation monitoring responsibility in the event of a nucleur accident,a nucleur war or potential terrorist nucleur detonation.to meet this commitment civil defence has trained a network of wardens throughout the country on the operation of two types of radiation detection and monitoring equipment. one is a low level radiation detector which can measure radiation down to normal background levels and would be used primarily to detect and measure radioactive fallout resulting from a nucleur industrial accident ,such as occoured in chernobyl.The second type of instrument would be used to detect and measure the far higher levels of radioactive fallout resulting from nucleur detonations in war. Under the goverments national emergency plan for nucleur accidents,The department of envoirment,heritage and local goverment is the co-ordinating body for the response of all goverment departments and agencies.under the plan a number of important and specific functions have been allocated to civil defence and the warden service would implement these.   * Conducting static radiation monitoring from a number of fixed points around the country * Collecting samples of differant types including soil,water and vegetation,and transporting them to the laboratories of the radiological protection institute of ireland (RPII) and other designated laboratories for analysis * Conducting Mobile monitoring in each of the local authority areas * Assisting,Where required in implementation of control measures   Training in general nucleur radiation topics and in the use of radiation detection instruments is provided for members,Scientific officers,who are members of civil defence supervise and manage this aspect.these officers are generally individuals with an engineering,scientific or other technical background.
