Hi guys, this is Nelsa, (finally) scribing for Friday's class. Whoot, everybody rejoice, hahaha.
ANYWAYS.
On Friday, we read chapter 3 in our Health Physics duotang, so.. you should probably do that if you haven't already. We answered the questions on pages 36, 39 and 41, which Ms. K posted the answers to on the previous post.
We read about a new formula on Friday too, I(d) = Ioe^-ud, which can be used to mathematically determince the amount of gamma radiation a substance will absorb. In the equation, Io stands for the original number of gamma rays (or incident intensity), I(d) is the number of gamma rays that don't pass through the substance, d represents the thickness of the substance and the coefficient u depends on the amount of energy the gamma ray carries. The higher the energy, the smaller the absorption coefficient.
Aaaand yeah, that's it. Don't forget to do your 'Sort and Predict' sheet, I think it's due today.
Next scribe will be.. George.
Cool.
'Kay bye.
