Spatial distribution of beta extremity doses in nuclear medicine: A feasibility study with thin α-AI₂O₃:C TLDs.
Phys. Med. 26, 44-48 (2010)
Exposures to the extremities have increased due to new therapeutic protocols involving beta sources. In this study, thermoluminescent dosimeters based on α-Al2O3:C were used to map the dose distribution to the extremities of physicians and paramedical personnel handling beta emitters. The results showed a strong inhomogeneous dose distribution between different phalanxes, fingers and hands of all the investigated subjects, without an indication of systematic trends in the dose patterns. Consequently, conventional dosimetric practices, based on the use of wrist or ring dosimeters, may be not suitable for providing reliable assessments of the inhomogeneous doses received at the fingertip.
