Thermoluminescence of Simulated Interstellar Matter after Gamma-ray Irradiation Forsterite, Enstatite and Carbonates
Interstellar matter is known to be strongly irradiated by radiation and several types of cosmic ray particles. Simulated interstellar matter, such as forsterite Mg2SiO4, enstatite MgSiO3 and magnesite MgCO3 has been irradiated with the Co gamma-rays in liquid nitrogen, and also irradiated with fast neutrons at 10 K and 70 K by making use of the low-temperature irradiation facility of Kyoto Univ...
متن کاملDepletion of Ovarian Primordial Follicles after Gamma Irradiation
Introduction:Artifical sourace of radiation have increased worldwide average annual exposure of mankind and could especially affect rapidly dividing cells in gonads. Since, radiation sensitivities of different components of primordial follicles, and the time required for their deplation have not been morphologically eatablished we decided to estimate the time required for depletion of primordi...
متن کاملInterstellar Gamma Ray Lines from Low Energy Cosmic Ray Interactions
Evidence for the existence of low energy cosmic rays in the Galaxy comes from the COMPTEL observations of gamma ray line emission from Orion, and also from light element abundance data which seem to suggest a low energy rather than a relativistic Galactic cosmic ray origin for most of the light elements. The Orion and light isotope data are more consistent with a composition that is depleted in...
متن کاملThermoluminescence characteristics and kinetic analysis of copper doped magnesium sulfate in gamma irradiation
MgSO4:Cu phosphor was synthesized by solid state method. Optimum concentration of copper was determined at 0.1 mol%. Thermoluminescence characteristics of MgSO4:Cu was studied following gamma irradiation. A linear dose response was observed in dose range of 1Gy to 500Gy. Reusability of this sample was tested after 10 cycles of gamma irradiation and it revealed that the intensity remains approxi...
متن کاملRheological properties of blood after whole body gamma-irradiation
Background: The study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. This work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. The applied shear rate was from 12 to 375 s-1. Low shear viscosity (up to 100 s-1) depends mainly on the erythroc...
