Kurie plot

  1. Mar 12, 2012 #1
    Hi...

    I have to measure the end point energy of a beta minus particle being emitted from a Sr-90 radioactive source. Part of this is plotting a Kurie plot. I am using a pulse height analyser (PHA) to get the beta spectrum (which counts how many beta particles are detected N,on the y-axis and has channel on the x-axis.)
    Now im pretty sure there is an easy way( one that doesnt involve any horrible maths) of doing a Kurie plot by using a variable current and plotting the square of that against N/I^2 (i think).
    But as im using a PHA I dont know how to plot a Kurie plot as theres no change in current that i can read!

    Any help as to how i should plot this?
