I would think that such medical investigation would should be done on a number of different islands.

I recommend a horticultural expert who should study the effects of the radiation on the vegetable foodstuffs and a marine biologist to consider the question of concentration of radioisotopes in the bodies of the larger fish. That some of these studies have been done before should not discourage similar studies by experts of your Gesignation.
