Calculation of equivalent dose for the lens of the eye in a positron field using EGS5
The equivalent dose rate per positron fluence for the human eye lens is calculated using a Monte Carlo simulation code, EGS5, with two mathematical models (a computational head voxel phantom and a simple eye model). The eye lens doses for medical staff and carers as received from a radiopharmaceutical such as F-FDG, which is used in PET examinations, when spilled on the floor, and from positron...
متن کاملOptimization of Head CT Protocol to Reduce the Absorbed Dose in Eye Lenses and Thyroid: A Phantom Study
Introduction: Utilization of computed tomography (CT) scans is increasing annually. This study aimed to reduce the absorbed dose of sensitive organs in the head (eye lenses and thyroid) and to assess changes in resultant images quality in head scans when the radiation dose is decreased. Material and Methods: An anthropomorphic phantom was examined with head protocols in both helical and sectio...
متن کاملA simple and effective technique to reduce staff exposure during the preparation of radiopharmaceuticals.
OBJECTIVE In the preparation of radiopharmaceuticals, staff receive considerable radiation exposure to the hands during withdrawal of activity from the elution vial, from a combination of the syringe and elution vial activities. In an attempt to reduce the radiation burden to the hands, a simple technique was developed that utilizes a modified lead pot lid and a syringe bearing a long needle wi...
متن کاملAssessment of Effective Dose Equivalent from Internal Exposure to 222Rn in Ramsar City
Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...
متن کاملMeasurement of dose equivalent of hand and eye of a nuclear medicine center technician during preparation of radiopharmaceutical containing 99mTc
Due to gamma irradiation by radioisotopes use for therapy and diagnostics proposes such as 99mTc, workers of nuclear medicine centers receives dose. Value of the dose equivalent of workers is determined using personnel dosimeters. Preparation, administration and injection of radiopharmaceutical are perfumed by technician so, the hand of technician received dose. In this paper the value of dose ...
