The
ambient dose of radiation therapy and nuclear medicine units of Clinical
Oncology Hospital, Menoufia University were investigated using thermoluminescence dosimeter
MTS-700 and surveymeter (Inspector Radiation Alert).The maximum% difference between read out of both
MTS-700 (TLD) and surveymeter did not exceed 6% and 8% for the two hospital
units respectively. Values of the annual ambient dose received in both hospital
units were found to be incompliant with radiation protection regulations. In
addition, the extremity effective dose Hp (0.07) of staff in nuclear medicine
unit was measured using wrist and finger techniques. Results indicate
in-homogenies distribution of fingertips doses. Radiation doses received by the
wrists and fingertips of radiopharmaceutical staff preparing99mTc
syringe were observed to be higher by a factor of about 1.41 and 1.44
respectively than those for the administrating staff whom injecting patients by 99mTc
syringe, but also still in congruent with
