Temporal dependence of $[{}^3{\mathrm{O}}_2](t)$ calculated for various in-air fluence rates (20, 50, 75, and $150\mathrm{mW}/{\mathrm{cm}}^2$) at depths of 1, 3, and 5 mm in the tumor for two initial BPD concentrations, [BPD]: (a)–(c) $0.57\mu \mathrm{M}$ and(d)–(f) $0.87\mu \mathrm{M}$. Photochemical parameters in Table 1 are used for $[{}^3{\mathrm{O}}_2]$ calculation using Eqs. (4) and (5).
