Recovery coefficient as a function of cell density (10⁶ cells/mL) and specific activity (kBq/10⁶ cells) for the 3 × 3 cubic-well plate. a Scatter plot of recovery coefficient vs. cell density and specific activity values and corresponding fit surface obtained through a logarithmic model function: y = 0.11 × log(CD × SA) + 0.57; CD = cell density; SA = specific activity. b Contour plot of specific activity as a function of recovery coefficient and cell density. The contours correspond to specific activities ranging from 10 to 50 kBq/10⁶cells. c Contour plot of recovery coefficient as a function of specific activity and cell density. Contour lines indicate recovery coefficients ranging from 0.1 to 1.0
