"WebThe uniformity of a gamma camera can be measured either intrinsically or extrinsically. In the intrinsic setup, the collimator is removed and the naked crystal is exposed to a low activity uniform flood source. This setup has the advantage that the measurements are not affected by collimator induced non uniformities. " - Gamma with uniform

WebWhich seemingly implies S = U V has uniform distribution and T has exponential distribution E x p ( 1). But this makes no sense because T = V and T has distribution Γ ( 2, 1). My notes tell me the substitution S = U V and T = U V give the right answer. But what is it that makes my substitution invalid and what went wrong with my working?
