Title

STAFF RADIATION DOSES ASSOCIATED WITH NUCLEAR PROCEDURES AND EFFICACY OF SYRINGE SHIELD FOR REDUCTION DOSE

Pages

  117-122

Abstract

 Introduction: Reduction dose of NUCLEAR MEDICINE STAFF with consideration of ALARA need to awareness of exposure manner and the effect of reduction dose methods, by way of measurement. NUCLEAR MEDICINE STAFF receive dose from two main localities of exposure, the first radiopharmaceutical consist of storage, milking, preparation, distribution and injection of radioactive substances and the second radioactive patient, patient who gives radioactive substances. In this investigation, we measured exposure from two main localities of exposure and efficacy of syringe SHIELD and apron for reduction dose. Material and Methods: Superficial and deep dose equivalent of chest (Whole body) gonads and superficial dose equivalent of fingers from two main localities for exposure was measured with lif (TLD-100) in four departments of NUCLEAR MEDICINE for a month. Superficial and deep dose equivalent before and after a lead plastic with 0.35 mmpb thickness was measured with TLD for a month. The superficial dose equivalent rate of syringe and syringe SHIELD was measured while syringes were contained 85, 370 and 740 MBq of Tc-99m. Results: Mean superficial and deep dose equivalent of chest and gonads were equal but superficial dose equivalent of fingers from radiopharmaceutical main locality of exposure was rather (P<0.05). Making use of apron was caused to reduce superficial dose equivalent but don't have effect on deep dose equivalent. Making use of syringe SHIELD was reduced dose equivalent. Conclusion: Equality of mean dose equivalent was due to increase of exposure of radiopharmaceutical main locality of exposure. Correct making use of syringes SHIELD was reduced exposure to 1.5 percentage of its primary. Making use of apron with 0.35 mmpb thickness was not reduced exposure because of high energy of photon that use in NUCLEAR MEDICINE. Survey of protective instrumentation was recommended for radiopharmaceutical main locality of exposure in departments of NUCLEAR MEDICINE.
