From: A swallowable X-ray dosimeter for the real-time monitoring of radiotherapy
a, Photograph of the experimental setup. b, Radioluminescence as a function of dose rate under 6 MV and 10 MV irradiation. c, Photograph of the experimental setup with a water tank containing water approximately 11 cm thick. d, Radioluminescence as a function of dose rate under 6 MV and 10 MV irradiation with a water tank at the front. e, Measured radioluminescence intensity over time at dose rates from 0.58 to 5.76 Gy/min. f, Radioluminescence of the nanoscintillators irradiated for 5 min at dose rates of 2.88 Gy/min and 5.76 Gy/min.
