A careful study is made of the different factors governing the choice of a γ-ray source, and other experimental parameters (scattering angle, collimation) when performing a Compton scattering experiment using a solid state detector. As is known, the poorer penetration of lower energy γ-rays leads to a lower count rate. It is found that an optimum choice of scattering angle and collimation can, in many cases, substantially offset this effect. A detailed comparison of the two sources most commonly used, viz. 241Am and 123mTe, is made. It is shown in contrast to what has been previously reported in literature, that 241Am can be quite a worthwhile choice. Some errors in previous findings are also pointed out.
