At present this contamination is negligible but the maximum tolerable level of radioactivity in food is not known. Research on this problem is, therefore, vital, The study committees of the National Academy of Sciences have accordingly recommended that: We should develop improved techniques to monitor worldwide fall-out from atomic radiation, | The national agency should control and keep records of all dumping of radioactive material in the ocean. fn international body should set up safe standards without delay, based on present knowledge, for the marine disposal of radioactive materials, Research tn marine disposal of radioactive waste products should be carried out on a cooperative international basis, Until advances in reactor technology lessen hazards substantially, reactors located near populated areas should be sealed against the release of radioactive materials in the event of an accident, - -3- OFFICIAL USE ONLY eines
