Stable Agar by Gamma Irradiation

Nature, 1967
DRY agar slowly deteriorates1 during storage, probably because of the degradation partly inherent in it and because of impurities which have not yet been identified, but processing stages designed to reduce sulphate2 and nitrogen seem to increase its stability.

Photoluminescence of gamma-irradiated Beryllium oxide

Applied Radiation and Isotopes, 2021
This study analyses the emission and excitation spectra of Beryllium Oxide (BeO) unirradiated and irradiated with 60Co gamma radiation because of its potential use in radiation dosimetry. Deconvolution of the spectra showed that using an excitation wavelength λexc = 330 nm, four emission bands centered at 404, 430, 468 and 545 nm are obtained; These ...

Gamma irradiation facilities

Radiation Physics and Chemistry (1977), 1981
Abstract A review is presented on the status and problem of gamma irradiation facilities for radiation processing. Requirements for the radioisotope source in the radiation processing and its comparison with electron accelerator are discussed. The gamma radioisotope source has speciality in the process of thicker products and source design, though it

Gamma-Irradiation of Kaolinite

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1961
AbstractStudies have been made of the changes in physical and chemical properties of kaolinite produced by doses of 0.667 meV gamma-radiation ranging from 1018 to 1022 eV/g of ferrous ion dosimetry solution. Changes were observed in the degree of crystallinity, specific surface area, particle size, cation exchange capacity, and grinding properties ...

Mobile gamma-irradiation robot

Radiation Physics and Chemistry, 1993
Abstract The source container with 98 TBq of 137 Cs and shielding made from depleted uranium has the total weight of 264 kg, height of 0.370 and diameter 0.272 m. The container is joined to accessories allowing movment of the radiation beam. The dose rate at a distance of 0.4 m in the beam axis is 50 Gy/h.

Gamma irradiation system’s performance tests

Radiation Protection Dosimetry
Abstract This study reviews the performance analysis of a 137Cs irradiation system that has recently been installed in the laboratory of Uzbek National Institute of Metrology. The laboratory is responsible for calibrating calibration facilities and for calibrating most protection level radiation monitoring instruments used in medical ...
