The Use of Gamma Radiation for the Treatment of Cultural Heritage in the Argentine National Atomic Energy Commission: Past, Present, and Future
(Springer Verlag Berlín, 2017-02)
The use of gamma radiation for treating biodeteriorated cultural heritage on paper has been studied at the Comisión Nacional de Energía Atómica-CNEA (Argentina) since 2001. In order to preserve books, publications, and ...
Effect of different gamma radiation doses on the germination and seedling growth of wheat and triticale cultivars
(Southern Cross Publishing, 2018-12)
Plant breeding of wheat and triticale in Argentina is based on the objective of improving an individual crop, with respect to resistance to drought stress. The use of gamma radiation holds promise for physiological crop ...
Rheological analysis of thermo-responsive alginate/PNIPAAm graft copolymers synthesized by gamma radiation
(Pergamon-Elsevier Science Ltd, 2019-03)
Focused on biomedical applications of thermo-responsive polymers, low-doses of gamma radiation from a 60Co source were applied in a simple one-pot method to synthesize graft copolymers of alginate and poly(N-isopropylacrylamide) ...
Effect of radiation-induced oxidative degradation on the non-isothermal crystallization of ethylene-butene copolymer
(Elsevier, 2019-12)
A random ethylene–butene copolymer was irradiated with high ionizing energy in environments with different oxygen concentration. The non-isothermal crystallization process of the materials was studied by differential ...
Contribution to the external gamma dose rate from 137Cs and 40K activity concentrations determined along the vertical profile of sandy beaches
(Springer, 2007-07)
Sampling sites, located along the Calabria and Basilicata Regions coastal beaches (south of Italy), were selected to assess the external gamma dose rate in air, 1 m above ground, and to estimate the fraction attributable ...
Gamma irradiated LDPE in presence of oxygen. Part I. Non-isothermal crystallization.
(Elsevier Science, 2013-08-06)
Non isothermal crystallization of low density polyethylene (LDPE) samples irradiated under three different atmospheres was analyzed. The used doses were between 33 and 222 kGy and the atmospheres content 0, 21 and 100% ...
Estudio preliminar de los efectos de las radiaciones gamma sobre los glóbulos rojos humanosPreliminar study of the effects of gamma radiations on human red blood cells
(Asociación Física Argentina, 2020-06)
En este estudio se analizaron los parámetros viscoelásticos y de agregación en glóbulos rojos humanos sometidos a los procedimientos habituales de irradiación gamma con fines transfusionales. Las muestras fueron irradiadas ...
Time delay between neutrinos and gamma-rays in short gamma-ray bursts
(Institute of Physics Publishing, 2019-02)
In this Letter we make an estimate of the time delay between signals, recorded at detectors on Earth, of neutrinos and photons originated in a short gamma-ray burst. We describe the geometry and dynamics of the system ...
Gamma rays and neutrinos from a cosmic ray source in the Galactic Center region
(American Physical Society, 2014-01)
The center of the our Galaxy is a region where very energetic phenomena take place. In particular, powerful cosmic ray sources can be located in that region. The cosmic rays accelerated in these sources may interact with ...
Effect of γ-radiation on green onion DNA integrity: Role of ascorbic acid and polyphenols against nucleic acid damage
(Elsevier, 2011-10-27)
The effect of γ-radiation on green onion DNA integrity, phenol content, oxygen radical absorbance capacity, employing pyrogallol red and fluorescein as probes, as well as ascorbic acid content has been evaluated. Measurements ...
