Estimates of effective and equivalent dose and limits for radiation workers (RWs) and the general public. The maximum dose rate measured was above the patient's abdomen ($0.4 \mu \text{Sv}/\text{hr}$), and the maximum measured total dose to any staff was $1 \mu \text{Sv}/\text{hr}$

Dose at Distance from Brachytherapy Implant Area	Expected Dose Rate ($\mu Sv/hr$)	Expected Dose (mSv)
Staff @ 1 meter with no patient shielding	${9.5}^{\mathrm{a}}$	${0.04}^{\mathrm{a}}$
Surgeons @ 30 cm		0.12
hands without Pb gloves @ 10 cm	–	1.12
@ 1 cm		112.3
Surgeons @ 30 cm		0.04
hands with Pb gloves @ 10 cm	–	0.39
@ 1 cm		39.3

^aThe annual equivalent dose limit is 50 mSv in Canada and the United States, or approximately $25 \mu \text{Sv}/\text{hr}$ over a 40‐hour work week. The expected dose calculation assumes a 2.5‐hour surgery duration.
