Message boards : Science : Beta versus Gamma attenuation
* I think I'm good on gamma --it's like light (photons). If I shine light through a 0.3d (50%) neutral density filter --there are half as many photons on the other side, but the color (energy) doesn't change. By extension, a "half value layer" of lead or concrete will reduce my Geiger CPMs by half, but I could still recognize the source's energy signature with gamma spectrometry --right? (Aside from a bit of line spreading --and that G-M tubes miss 98% of the gammas.)

Thank you, "exsafs". Your explanation, has helped me understand what's going on when the beta count unexpectedly falls off to nothing.
