Purpose: Recently a new design of a 125 I brachytherapy source was introduced for interstitial seed implants, particularly for prostate seed implants. This new source is the EchoSeedTMModel 6733 125 I brachytherapy source. Due to the differences in source design and manufacturing process from one new source to the next, their dosimetric parameters should be determined according to the American ...

The handling of a liquid radioactive source is a procedure that is uncommon for the average clinical medical physicist. A newly approved treatment device utilizes high activities of liquid I-125 solution as the source of radiation. The radiation safety issues and our experience utilizing high activity liquid I-125 sources are presented. To date we have treated 22 patients with infused activitie...

Background and Objectives Intra-parenchymal brain surgical resection cavities usually contract in volume following low dose rate (LDR) brachytherapy implants. In this study, we systematically modeled and assessed dose variability resulting from such changes for I-125 versus Cs-131 radioactive sources. Methods Resection cavity contraction was modeled based on 95 consecutive patient cases, using ...

objectives this study examined 125i concentrations in the edible parts of five types of plants from different locations on farms with a similar climate. near zahedan, iran. background radioiodine 125i is an environmental contaminant that humans may consume in edible plants. the characteristics of 125i in plants are poorly understood. materials and methods the experiments used a mini-column appr...

ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...
