    Probability of Beta Particle Detection from Uniformly Covered Surface

    I really appreciate the advice! The last time I computed double integrals was in Calc 3 a couple years ago. I now see that using integrals in practice is slightly different than when computing them in a class. I understand the basic concepts, but am rusty on the details. Thanks alot!

    Probability of Beta Particle Detection from Uniformly Covered Surface

    One question I have for you though...How did you come up with the 11.8%? I'm also curious where f(theta) = sin(theta) comes from in this formula? Thanks for your input.

    Probability of Beta Particle Detection from Uniformly Covered Surface

    Ok...I think I see how to handle this. What I did was computed the dbl integral above symbolically to get, \int _ {\phi = 0}^{2\pi}d\phi \int _ {\theta = 0}^{\pi}sin \theta d\theta = -(phi-2*pi)*(cos(theta)+1) = 4\pi Now I can describe phi and theta in terms of the offset distance...

    Probability of Beta Particle Detection from Uniformly Covered Surface

    Thank you for your response. Percentage = 100_cm^2/(11.9_cm^2) = 8.40 = 840% On the other hand, if I flip the ratio, Percentage = 11.9_cm^2/100_cm^2 = 11.9% I thought of trying this yesterday; however, I figured this was too good to be true. Shouldn't the percentage be...

    Probability of Beta Particle Detection from Uniformly Covered Surface

    We have a surface that is 10 cm x 10 cm. That surface is uniformly covered with a radioactive material. When radioactive material decays, it has a equal probability of emitting radioactive particles, in this case beta particles, in any direction (360 degrees). We have a detector that...

    Vibro Acoustics Senior Design Project

    Thanks for your input... Violin Acoustics What if as a result of using modern day experimental test instrumentation, we were able to find a way to get the same sound quality (or “timbre”) as is obtained from aged instruments? What if we were able to get this same sound quality (or better)...

    Vibro Acoustics Senior Design Project

    Hello All, My partner and I are mechanical engineering technology students who are in search of a feasible senior design project related to acoustics. During the first semester we will be doing the theoretical parts then during the second semester we will be doing the hands-on...
