Carbon Nanotube Based Dosimetry of Neutron and Gamma Radiation
… 20 years, accurate information regarding neutron radiation exposure is more important than ever. Structural components such as the reactor pressure vessel (RPV) become embrittled by neutron irradiation, reducing their capability to resist crack growth and increasing the risk of catastrophic …

The Effects of Neutron and Gamma Radiation on Graphene
… be fully developed, the response to neutron and gamma irradiation must be understood. In this study, graphene grown from chemical vapor deposition was irradiated by the High Flux Isotope Reactor at Oak Ridge National Laboratory and characterized using Raman spectroscopy. It was found that the …

Acoustic Waveguides and Sensors for High Temperature and Gamma Radiation Environment
… are developed for high temperature and heavy gamma radiation. The periodic structure, acoustic fiber Bragg grating (AFBG), is the core sensor structure in this dissertation. To better analyze the propagation of acoustic waves, the acoustic coupled more analysis is proposed. It could solve for …

Cytogenetic Evaluation Of Low Dose Hyper-Radiosensitivity In Human Lymphoblastoid Cell Lines Exposed To Cobalt-60 Gamma Radiation.
… relationships of cells exposed to ionizing radiation are frequently described by linear quadratic (LQ) models over an extended dose range. However, many mammalian cell lines, when acutely irradiated in G2 at doses below 30 cGy, show hyper-radiosensitivity (HRS) as measured by reduced …

Characterization of DNA-repair potential in deep subsurface bacteria challenged by UV light, hydrogen peroxide, and gamma radiation
… Program were tested for resistance to UV light, gamma radiation and H₂0₂. Some deep subsurface bacteria were resistant to UV light, demonstrating ≥1.0% survival at fluences which resulted in a 0.0001% survival level of E. coli B. The percentage of UV resistant aerobic subsurface bacteria and …

Novel thermoluminescent dosemeter for the measurement of the eye lens operational dose equivalent in mixed neutron-gamma radiation fields
… Canadian Nuclear Safety Commission amended the Radiation Protection Regulations in their recent document “REGDOC-2.7.2, Dosimetry, Volume I: Ascertaining Occupational Dose”, reducing the equivalent dose limit for the eye lens of a nuclear energy worker from 150 mSv to 50 mSv in a one-year …

Morphological and histochemical observations of hepatic peroxisomes and lysosomes of rats after treatment with methylmercuric chloride, hydrogen peroxide and gamma radiation
… peroxide (HP), methylmercuric chloride (MMC) and gamma radiation (I). The HP group received five daily intraperitoneal (IP) injections of 1.8 ml of 1.5% HP; the MMC group received a single IP injection of 6 mg MMC per kg body weight; the I group received 750 R whole body irradiation. Morphometric …

Modification of fecundity and fertility during oogenesis by gamma radiation and/or ozone with a cytological analysis in the ectoparasitic wasp, Habrobracon juglandis (Ashmead)
… exposed to 0, 25, 35, 45, and 65 Gy of Co-60 gamma radiation. All treated wasps showed significant progressive decreases in fecundity and fertility with increases in radiation dose; females given 45 and 65 Gy experienced temporary infecundity and permanent sterility, respectively. The results …

The effects of radiation on pregermination plant seeds
… tissue, we have investigated the effects of gamma radiation and hyperthermia on barley and alfalfa. Barley seeds soaked for up to 16h prior to irradiation were given doses of gamma radiation up to 100 Gy, and alfalfa seeds soaked for up to 24h were given doses up to 500 Gy. The mean …
