| Background: Sentinel node biopsy (SLNB) is the
standard of care for breast cancer treatment and it is
getting wide acceptance in Iran. The radiation safety
of the procedure has been investigated under
controlled conditions, but the standard dose of radiotracer
and techniques are not always observed in the
community setting. The aim of this study was to
assess the magnitude of the absorbed doses of radiation
to the hands of operating surgeons. Materials
and Methods: Twenty consecutive SLNB procedures
were studied. Radiation dose to the hands of the
surgeons was measured by placing lithium fluoride
thermoluminescent dosimeters (TLDs) in the
surgeons' glove. The radiation dose to the abdomen
and thyroid area was measured by placing TLDs at
these areas. The injected dose of radiotracer, the
time interval to the surgery and the duration of the
surgery were recorded. Results: The injected dose of
radiotracer ranged from 0.1 to 5 mCi. The highest
absorbed dose was recorded by TLD, placed on the
non-dominant hand third finger (189.1 μSv). Mean
recorded doses were higher for non-dominant hand
second finger (53.49 ± 24.60 μSv). The measured
absorbed doses for the abdominal and thyroid area
were lower than those for the fingers. Conclusion:
This study has confirmed the procedure safety, even
with high dose of radiotracer. Nevertheless, it is
advisable to use the lowest dose of the radiotracer to
avoid the waste of resources. Iran. J. Radiat. Res.,
