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.

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

Cardiovascular Radiation Medicine, 1999
Abstract Background. The debate over which radioisotope, gamma-emitting or beta-emitting, is ideal for vascular brachytherapy, is as old as the field itself. Gamma isotopes such as Ir-192 have been successfully used in large-scale clinical trials. However, radiation protection and safety remains a practical issue when high energy gamma rays are used

Aquoluminescence from Gamma-irradiated Alkali Halides
Nature, 1970WE report here the observation of a faint bluish green glow with a peak around 5000 A when gamma-irradiated NaCl, NaBr, KCl or KBr is dissolved in distilled water. To observe the glow the room must be dark and the eye must be acclimatized to the darkness for a few minutes.

Gamma irradiated crosslinked cellulose
Journal of Polymer Science Part B: Polymer Letters, 1963Investigations were made on the effects of gamma radiation on the physical properties of cellulose crosslinked with formaldehyde. The mechanism of the crosslink reaction was also studied. Solubility and viscosity, x-ray diffraction, trapped radicals, and water sorption were studied in the irradiated crosslinked fabric. It appeared that the formaldehyde

Gamma and electron irradiation
Physics Bulletin, 1969The UK Panel on Gamma and Electron Irradiation was set up in 1963 by the coming together of industrial organizations, the UK Atomic Energy Authority, the Ministry of Health and interested individuals mainly from the universities. Originally its purposes were connected with the promotion of fundamental and applied research into the use of radiation for ...

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 ...
