Extended Data Fig. 10: Irradiation administration via the capsule.
From: A swallowable X-ray dosimeter for the real-time monitoring of radiotherapy
a, Temperature change recorded by the capsule over time in a stable experimental environment. b, Change in capsule pH over time, as measured by the persistent luminescence of NaLuF4:Tb@NaYF4 nanoscintillators. c–e, Time-course results of the absorbed dose, pH, and temperature of different capsules in two rabbits. f, Correlation between dose rate and pH changes. The correlation coefficient was obtained by linear fitting.
