Gamma-Rays Absorption Studies of Garnet series of Gemstones at 1 Kev to 100 GeV: Theoretical Calculation
نویسندگان
چکیده
Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy and composition of the garnet series of gemstones. Half value layer (HVL) and tenth value layer (TVL) has also been calculated; whose lower value reveals the good shielding ability for gamma rays. Hence it is concluded that GS4 shows the maximum shielding effectiveness and also GS6 and GS3 seem to have good radiation shielding. It is also analyzed that our calculated mass attenuation coefficient of NBS concrete by the present method are in excellent agreement with standard values given by ANSI/ANS-6.4.3 data.

Results of a phenomenological model to estimate the GRB detection rate by the Fermi Gamma ray Space Telescope are reported. This estimate is based on the BATSE 4B GRB fluence distribution, the mean ratio of fluences measured at 100 MeV – 5 GeV with EGRET and at 20 keV – 2 MeV with BATSE, and the mean EGRET GRB spectrum for the 5 EGRET spark-chamber GRBs. For a 10% fluence ratio and a number spe...
