Preliminary investigations were recently made in laboratory on the effects of low-levelradioactivity contaminated by radioisotopes using embryonic of mussel (Mytilus edulis) andsea-urchin (Hemicentrotus pulcherrimus) as the material. The gametes and various stagesof fertilized eggs of mussel and sea-urchin were maintained in seawater contaminated with~(137)Cs (~(131)I or ~(32)P) over the concentration range 10~(-10)Ci/L to 10~(-2) Ci/L. The effects
