    Points close to the source not behaving like inverse-square

    Thank you for the replies. I'm trying to obtain the technical specs. for the counter, which will allow me to know both the resolution and tube length, and then I will check your suggestions. Another thing a friend suggested is that because the loss from inverse-square at this distance is very...

    Points close to the source not behaving like inverse-square

    Homework Statement The problem - confirm that the amount of radiation measured from a source is related by inverse-square to the distance. Here is a graph of my data fitted to y = a1 * x^a2. Every point is an average of 3-8 measurements (as many as needed to have a statistical error of...

    Poisson distribution (radioactive decay)

    Thanks, it WAS a code problem.

    Poisson distribution (radioactive decay)

    I'm sorry, I don't understand why e is ^-k, all the formulae I've found have e^-λ, which is a constant thanks for the reply

    Poisson distribution (radioactive decay)

    Homework Statement I am a freshman in physics, just done a lab about radioactive decay. I've measured the # of beta particles per second 400 times and got the frequency of each number K using Excel. I'm supposed to take the data and fit it to a puason distribution in MATlab. The data points...
