FIGURE 2. Stray scatter profile along bed axis measured by open thermoluminescent dosimeters for ²⁰¹Tl ( ${blacktriangleup}$ ), ¹⁵³Gd (•), and ^99mTc ( ${blacksquare}$ ) line sources in gamma camera. Constant value in field of view is assumed. Biexponential fits are given (dashed lines). Dose rate values are normalized to unit source strength. A reference man is schematized along horizontal axis.
