What is the half-life of barium and krypton and any other radioactive byproducts that are formed from nuclear fission?

This is an extensive subject, I cannot summarise all the isotopes formed into one answer. I suggest you go to the Wikipedia link given below, if that is not detailed enough there are other tables and charts available, an internet search should find several.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
