Photo of the green bar-shaped phantom (a) and radioactivity distribution along the phantom (b) as determined on a radio-TLC system (c). Integration of radioactivity counts for each of the ten 1-cm-sections (S1–S10) on the TLC system resulted in almost identical values (~ 1.3 × 106 counts) with a relative standard deviation (RSD) of 0.5%
