Reply #122: Note my error in post #82. I noticed this in preparation for the Tc

[NNadir]

series.

I wrote in #82: "Most heavy nuclides have fission product distributions that look like camel humps and fissioning heavier nuclides move the hump reflecting the higher mass nuclides, that on the right, slightly to the right, toward heavier fission products. (The effect on the most important element in the heavy part of the fission product hump, Cesium, is slight.)"

I wrote this relying on my memory. However, in preparing post #113 on technetium, I actually re-read the (Seaborg and Loveland) text in my home library on the asymmetry of fission and note that it is the heavy group is more or less constant, and it is the light group (on the left) that moves toward higher atomic mass numbers. Thus my post #113 is correct and my post #82 is incorrect with respect to fission asymmetry. I think it's minor but I apologize for my lack of self checking in that case. I've been working too hard lately.

This concludes my series on the special dangers and "bad news" about the long lived fission product technetium, since I can't think of any more difficulties about the stuff. If however any one has any factual additions or corrections, I welcome them.

I will soon begin posting to a series discussing the mitigating factors, uses, and risk reduction strategies available for technetium management and applications.
