Radial doses are calculated for the following therapeutic radioisotopes: (b) ²¹³Bi and ²²³Ra; and (b) ⁹⁰Y, ¹⁷⁷Lu and ⁶⁷Cu (note the different dose scales in the two plots). (c) Cross section of the GATE simulation geometry set-up for radial dose distribution around a single radio-FH nanoparticle (white, red and yellow represent the SPIO core, radiolabeled layer and polymer coating, respectively): a detector comprising concentric spherical shells (light and dark blue) with equidistant intervals of 1 nm is centered on a single radio-FH nanoparticle and extends from its surface (at a radius of 8.5 nm) to a radius of 100 nm.
