Stable Agar by Gamma Irradiation
Nature, 1967DRY 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.

Effects of gamma irradiation on aflatoxins
Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1987The effects of gamma irradiation on a mixture of aflatoxins B1, B2, G1, G2 were studied. Standard solutions of A and B were irradiated at 5, 10, and 20 kGy in a solution of water/DMSO (9 + 1, v/v) by using a 137Cs source. The control (0 kGy) and irradiated samples were subjected to RP-HPLC analyses with methanol/water (4 + 5, v/v) as the mobile phase ...

Photoluminescence of gamma-irradiated Beryllium oxide
Applied Radiation and Isotopes, 2021This 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 of Kaolinite
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1961AbstractStudies 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 ...

Gamma Irradiation of Stentor polymorphus
The Journal of Protozoology, 1969SYNOPSIS. Stentor polymorphus was irradiated with 60Co gamma rays at 525 rads/minute to examine the effect on survival, cell division, oral membranellar frequency and oxygen uptake. Both survival and cell division were studied on single cells. The LD50 is 285 kilorads but cell division is inhibited below this dose; 110 kilorads doubles the 1st post ...

Safety Systems in Gamma Irradiation Facilities
Health Physics, 1997A new electronic device has been developed to guard against individuals gaining entry through the product entry and exit ports into our irradiation facility for industrial sterilization. This device uses the output from electronic sensors and pressure mats to assure that only the transport cabins may pass through these ports. Any intention of personnel

Gamma Irradiation of Silicones
Journal of Inorganic and Organometallic Polymers and Materials, 2008Silicones in various forms have been utilized in biomedical applications over the past several decades. While silicone elastomers are currently the most common silicone biomaterial, low molar mass cyclic silicones, low molar mass linear silicones, silicone oligomers, silicone polymers and silicone gels have each found applications as biomaterials.

Sterilisation of skin allograft with gamma irradiation
Burns, 2008The primary surgical requirement of skin allografts within the UK is for cryopreserved viable allografts as these engraft to the wound bed and gain a vascular supply, thus providing true wound closure and a superior clinical performance. Consequently the only disinfection treatment the skin receives is exposure to an antibiotic cocktail.

Gamma Irradiation and Fermentation
2016This chapter discusses the applications of gamma irradiation technology for food safety, its nutritional implications, and its involvement in fermentation processes. Gamma irradiation has become an alternative technology for food sterilization due to its nonthermal character, thus replacing the conventional heating processes. Several driving forces are

EFFECTS OF GIBBERELLIN ON GAMMA‐IRRADIATED WHEAT
American Journal of Botany, 1960Haber, Alan H., and Helen J. Luippold. (Oak Ridge National Laboratory,2 Oak Ridge, Tenn.) Effects of gibberellin on gamma‐irradiated wheat. American Jour. Bot. 47(2): 140—144. Illus. 1960.–After receiving large doses of gamma rays, wheat grains can germinate and grow into small seedlings, either in water or in a solution of gibberellic acid, without ...
