Radiation doses recorded in the ICs of the IMTCs in the radiochromic film study in Figure 4 .
| Data source | Position in IMTC | Run Number | Mean ± SD | ||
|---|---|---|---|---|---|
| 1 | 2 | 3 | |||
| Radiation dose received (Gy) | |||||
| Alanine dosimeter | B | 49.6 | 49.7 | 49.4 | 49.6 ± 0.15 |
| Radiochromic film | E | 42.9 | 41.8 | 42.5 | 42.4 ± 0.56 |
| F | 38.3 | 38.5 | 39.5 | 38.8 ± 0.64 | |
| H | 46.9 | 47.1 | 47.4 | 47.1 ± 0.25 | |
| Radiation dose ratio | |||||
| Dose uniformity | H/F | 1.225 | 1.223 | 1.200 | 1.216 ± 0.014 |
| Adjustment factor, minimum dose | F/B | 0.772 | 0.775 | 0.800 | 0.782 ± 0.015 |
| Adjustment factor, maximum dose | H/B | 0.946 | 0.948 | 0.960 | 0.951 ± 0.008 |
The doses received at the center of each film (location E), at the minimum dose location (location F, up to 2019), and the maximum dose location (location H) are shown together with the doses received by the reference alanine dosimeters at location B. Dose uniformity describes the range of dose between the maximum dose location (H) and the minimum dose location (F) expressed as H/F. The adjustment factors for estimating the minimum dose at F and the maximum dose at H from the dose received by the reference dosimeter at B are also included.
