Experimental set-up for ⁹⁰Y. a Two sets of ⁹⁰YCl₃ (HDR, LDR) activity concentrations were added to the cell plates. Each cell line was plated into two plates with range of 0–62 Gy. The red markers show row of wells that contains the cell without activity. b Schematic diagram illustrating (i) the distribution of cells and ⁹⁰Y source in two 96-well plates for HDR–⁹⁰Y set (similar set-up was prepared for LDR–⁹⁰Y set), (ii) demonstrating a single-well containing the ⁹⁰YCl₃ and cells in RPMI cell medium
