This book was released on 1962 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the use of an air-filled aluminum-alloy ionization chamber to determine the energy transported by a bremsstrahlung beam with maximum photon energy in the range 6 to 170 Mev. The experimental calibrations of this chamber over this energy range are given, as well as the results of calibration experiments made with a 250-kv constant-potential X-ray tube and with Cs137 and Co60 gamma-rays. Information is presented about the change in calibration when the chamber is used with different experimental conditions, and when either its dimensions or its alloy composition are changed slightly. This report can be used to construct a replica chamber and to determine its absolute calibration between 6 and 170 Mev under a variety of experimental conditions.

This book was released on 2000 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Code of Practice, which has also been endorsed by WHO, PAHO and ESTRO, fulfils the need for a systematic and internationally unified approach to the calibration of ionization chambers in terms of absorbed dose to water and to the use of these detectors in determining the absorbed dose to water for the radiation beams used in radiotherapy. It provides a methodology for the determination of absorbed dose to water in the low, medium and high energy photon beams, electron beams, proton beams and heavy ion beams used for external radiation therapy.

Download or read book Airport Passenger Screening Using Backscatter X-Ray Machines written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-01-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passenger screening at commercial airports in the United States has gone through significant changes since the events of September 11, 2001. In response to increased concern over terrorist attacks on aircrafts, the Transportation Security Administration (TSA) has deployed security systems of advanced imaging technology (AIT) to screen passengers at airports. To date (December 2014), TSA has deployed AITs in U.S. airports of two different technologies that use different types of radiation to detect threats: millimeter wave and X-ray backscatter AIT systems. X-ray backscatter AITs were deployed in U.S. airports in 2008 and subsequently removed from all airports by June 2013 due to privacy concerns. TSA is looking to deploy a second-generation X-ray backscatter AIT equipped with privacy software to eliminate production of an image of the person being screened in order to alleviate these concerns. This report reviews previous studies as well as current processes used by the Department of Homeland Security and equipment manufacturers to estimate radiation exposures resulting from backscatter X-ray advanced imaging technology system use in screening air travelers. Airport Passenger Screening Using Backscatter X-Ray Machines examines whether exposures comply with applicable health and safety standards for public and occupational exposures to ionizing radiation and whether system design, operating procedures, and maintenance procedures are appropriate to prevent over exposures of travelers and operators to ionizing radiation. This study aims to address concerns about exposure to radiation from X-ray backscatter AITs raised by Congress, individuals within the scientific community, and others.

Book Synopsis Calibration of X-ray Ion Chambers for the Space Environment Monitoring System by : Arlyn Unzicker
Download or read book Calibration of X-ray Ion Chambers for the Space Environment Monitoring System written by Arlyn Unzicker and published by . This book was released on 1974 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the steady-state of the ion-chamber current output to the incident energy flux of a monochromatic X-ray beam are reported for the 1/2-3 Å and 1-8 Å ion chambers for the NOAA Space Environment Monitoring System. Bragg crystal reflection was employed to obtain a monochromatic beam. Proportional counters were used to measure the absolute intensity of the monochromatic X-ray beam. An ultra-sensitive electrometer was used to measure the current output of the ion chamber, including currents as small as 10−15 amps with noise levels as low as about 10−16 amps. The calibration results are compared with the theoretical transfer function. The effects of anode structures on reducing the effective total area of the ion chambers were observed as a function of wavelength. The influence of small regions of epoxy overlying the window was examined.
