Question about a geiger counter's resolving time

  1. Oct 15, 2006 #1
    Given that R=r/(1-rT) where R is the true counting rate and r is the observe counting rate

    show that T=(R1+R2-R3)/(2R1*R2) where T is the resolving time

    I've tried all kinds of plugging in and fiddling and what have you, but I can't quite figure it out. I understand in this equation R3 is the observed time of R1 + R2 together under the counter

    The closest I got was solving that first equation for T=1/r-1/R and using R3 for r and R1+R2 for R, and doing that the numerator comes out correct but the denominator is R3(R1+R2)
