Dosimetric implications
Patient
- Up to 2Gy local skin dose - deterministic threshold reached (transient erythema)
- More likely to be mean of <200mGy if used carefully
Operator
- Dose rate to hands can be high (up to 4mGy/s)
- Sensible use should limit this
- Trunk dose rate in region of 0.5mGy per procedure - lead apron use essential
