To modernize the management of sensitive nuclear materials, Argonne National Laboratory has developed the ARG-US radio frequency identification (RFID) system for the Packaging Certification Program of the U.S. Department of Energy (DOE), Office of Packaging and Transportation. The system consists of battery-powered RFID tags, a reader network, an application software suite, secured database ser...
The main aim of this double blind randomized clinical trial was to determine and compare the results and complications of using Catgut chromic (biologic ) and Vicryl rapide (sytlthetic) as a suture material in episitomy repair. 46 primiparus women were entered in this study randomly. Episiotomy of 2/ women were rep aired by Vicryl rapide and 25 by Catgut chromic. These two groups were mat...
Radiation processing in many areas, particularly in radiation sterilization, demands control of the absorbed dose. Many dosimeters have been proposed for the high-level dose range (region of 10 to 50 kGy). However, in addition to the required reproducibility, reliability or uncertainty (< 5%), it is desirable for radiation processing that the selected dosimetric system is easy to operate. One o...
background: over recent decades, modern protocols of external beam radio¬therapy and radiation techniques such as intensity-modulated radiotherapy (imrt) have been developed. these methods are extremely sensitive to errors in treatment delivery, so that it is essential to apply a high resolution 3d dosimetry system that has high sensitivity and is capable of measuring and verifying the complex ...
Optical computed tomography (CT), in conjunction with radiochromic gels and plastics, shows great potential for radiation therapy dose verification in 3D. However, an effective quality assurance (QA) regime for the various scanners currently available still remains to be developed. We show how the favourable properties of the PRESAGE® radiochromic polymer may be exploited to create highly sophi...
Very high energy electrons (VHEE) in the range from 100-250 MeV have the potential of becoming an alternative modality in radiotherapy because of their improved dosimetry properties compared with MV photons from contemporary medical linear accelerators. Due to the need for accurate dosimetry of small field size VHEE beams we have performed dose measurements using EBT2 Gafchromic® film. Calibrat...
PURPOSE OF THE STUDY With rapid development in the field of nuclear medicine therapy, radiation safety of the personnel involved in synthesis of radiopharmaceuticals has become imperative. Few studies have been done on estimating the radiation exposure of personnel involved in the radio labeling of 177Lu-compounds in western countries. However, data from the Indian subcontinent are limited. We ...
