Download or read book MONTE CARLO CALCULATIONS OF GAMMA RAY ALBEDO written by and published by . This book was released on 1965 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Monte Carlo computer program has been used to generate values for the differential dose albedo of gamma rays on concrete. The values have been fit to a semiempirical formula containing two adjustable parameters. Values for the parameters are reported as a function of gamma-ray energy.

Download or read book Differential Dose Albedos for Calculation of Gamma ray Reflection from Concrete written by M. B. Wells and published by . This book was released on 1964 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential dose albedos for gamma ray reflection from concrete were derived from Monte Carlo calculations of gamma ray scattering in air and concrete for source energies of 0.6, 1, 2, 4, and 7 Mev. Curves showing the albedo for reflection in the plane of incidence are presented for angles of incidence of *c = 0DG, 30DG, 45DG, 60DG, and 75DG. At incident energies greater than 2 Mev the computed dose albedos are smaller than those reported by Raso (also based on Monte Carlo) and those given by the Chilton-Huddleston formula. However, comparisons with experimental data for Cs-137 and Co-60 gamma rays reported by Jones, Schofield, Haggmark, and Gurney of USNRDL, C. E. Clifford of DRCL, and Barrett and Waldman of Technical Operations, Inc., indicate that the calculated albedos for these sources agree as well with the experimental data as do calculations based either on the Chilton-Huddleston formula or Raso's Monte Carlo calculations.

Available in PDF, EPUB and Kindle. Book excerpt: An intercomparison is made between the results of Monte Carlo calculations and two independent experimental determinations of values for the differential dose albedo of gamma rays on concrete. The validity of a semiempirical formula for gamma-ray albedo is examined. Information is presented on the current status of our knowledge of gamma-ray albedo, and the direction of future work is indicated. (Author).

Download or read book The Gamma ray Albedo of the Moon written by and published by . This book was released on 2007 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use the GEANT4 Monte Carlo framework to calculate the [gamma]-ray albedo of the Moon due to interactions of cosmic ray (CR) nuclei with moon rock. Our calculation of the albedo spectrum agrees with the EGRET data. We show that the spectrum of [gamma]-rays from the Moon is very steep with an effective cutoff around 3-4 GeV (600 MeV for the inner part of the Moon disk) and exhibits a narrow pion-decay line at 67.5 MeV, perhaps unique in astrophysics. Apart from other astrophysical sources, the albedo spectrum of the Moon is well understood, including its absolute normalization; this makes it a useful 'standard candle' for [gamma]-ray telescopes. The steep albedo spectrum also provides a unique opportunity for energy calibration of [gamma]-ray telescopes, such as the forthcoming Gamma Ray Large Area Space Telescope (GLAST). Since the albedo flux depends on the incident CR spectrum which changes over the solar cycle, it is possible to monitor the CR spectrum using the albedo [gamma]-ray flux. Simultaneous measurements of CR proton and helium spectra by the Payload for Antimatter-Matter Exploration and Light-nuclei Astrophysics (PAMELA), and observations of the albedo [gamma]-rays by the GLAST Large Area Telescope (LAT), can be used to test the model predictions and will enable the LAT to monitor the CR spectrum near the Earth beyond the lifetime of the PAMELA.

Our calculation of the albedo spectrum agrees with the EGRET data. We show that the spectrum of gamma-rays from the Moon is very steep with an effective cutoff around 3 GeV (600 MeV for the inner part of the Moon disc). Since it is the only (almost) black spot in the gamma-ray sky, it provides a unique opportunity for calibration of gamma-ray telescopes, such as the forthcoming Gamma Ray Large Area Space Telescope (GLAST). The albedo flux depends on the incident CR spectrum which changes over the solar cycle. Therefore, it is possible to monitor the CR spectrum using the albedo gamma-ray flux. Simultaneous measurements of CR proton and helium spectra by the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA), and observations of the albedo -rays by the GLAST Large Area Telescope (LAT), can be used to test the model predictions and will enable the GLAST LAT to monitor the CR spectrum near the Earth beyond the lifetime of PAMELA.
