Monitoring using spectrograms?

Data collection not quite complete (later today) but I have a statistically significant K-40 peak detected now.

Another interesting project is tobacco leaves which alegedly concentrate Polonium (I read somewhere) and that contributes to it's carcinogenic properties. However it is a weak alpha emitter so probably not easy to discriminate and so the 103 might not be up for it. Perhaps the 103-G would have been a better option for these experiments but it's a lot more expensive.

Final result - the only detectable peak is at 1480KeV which is likely K-40 but shows calibration is off because it should be 1461KeV. Now I'll start a 48hr background.

(I should have split the last few posts off into a new topic about bananas!)

 

Looking forward to your results!

I'll post results on banana experiment in a new thread.
