OK guys... way to much info to post, but i'll do 1 snip...
this is a thesis about biological radiation by Dr Rosalie Bertell.....

... it is an excellent in-depth (very long read)...

The Seed


The future of humankind is present today within the bodies of living people, animals and plants -- the whole seedbearing biosphere. This living biosystem which we take so much for granted has evolved slowly into a relatively stable dynamic equilibrium, with predictable interactions between plants and animals, between microscopic and macroscopic life, between environmental pollutants and human health. Changes in the environment disturb this balance in two ways: first, by altering the carefully evolved seed by randomly damaging it, and second, by altering the habitat, i.e. food, climate or environment, to which the seed and/or organism has been adapted, making life for future generations more difficult or even impossible.
Although examples of maladaptation in nature and resulting species extinction abound, our focus here is on human seed, the sperm and ovum, and the effect on it and on the human habitat resulting from increasing ionising radiation in the environment.

you might want to set aside a bit of time for this one....

... a bit like an a.b.c or bible if you are following fukushima, and indeed radiation issues around the planet....
