Half life no longer constant.

i think thats what i said..an average would represent readings in different enviromental and statistical factors, but i think my assessment of the theory was questioned . I think i will read the book you suggested, sounds like a good read.
I dont "hate"...i strongly dislike lol
have a good night :)

Like I said in one class when asked how would you Shield something in real life. I said I would use what they used the last time they did it and verify it , and if I had to do it the first time I would throw lead on it till I got the reading I wanted. Now chill it is still fun to talk about and see what changes the half life or half value layer.

Some more variables woudl be the Z-number of the radionuclide in question, and the neutrino energy of concern.

That book is excellent. The first 60% or so is about how the various physicists figured things out and the incredible ingenuity they used to prove their theories. What I found interesting is how they "discovered" thermalization of neutrons. A physicist had neutron sources sitting underneath a table made f marble and one of wood. He was performing some sort of survey that had nothing to do with the neutrons and noticed the instrumentation he was using responded differently as he passed each table From that they figured out that Wood must somehow change energies of neutrons.
The way they figured out Atomic Mass is AMAZING. Those old timers weren't only smart, they were clever and master craftsmen.

Now that sounds awesome !! I love books that teach with such great examples of field ingenuity :) Im going right to amazon to order it. The last book i so enjoyed was Richard Feynmans QED, The Strange Theory of Light and Matter. His humour and quirky little mathmatical drawings made the topic easier to understand.
