201Tl radiotoxicity—internal vs external 201Tl. a 201Tl uptake in DU145 cells in PBS with different concentrations of K+ (0–25 mM) after 90 min incubation with 4000 kBq/mL of [201Tl]TlCl. b Average number of foci per nucleus and c clonogenic survival measured in DU145 cells after 90 min incubation with 4000 kBq/mL of [201Tl]TlCl and 15 or 25 mmol/L KCl and various non-radioactive controls (NC1-4). Data are presented as mean ± SD, n = 3, triplicates, * indicates P < 0.05
