Effect of gamma-irradiation on aqueous solutions of Apollofix dyes
Textile dyeing wastewater is one of the major environmental problems in Turkey and is a common problem faced by many countries. These types of wastewaters are generally high in biological oxygen demand (BOD), chemical oxygen demand (COD), total solids, and strongly colored. Neither simple chemical nor biological treatment has proved to be adequate in removing the color and organic matter. It is...
متن کاملQuality control of blood irradiation with a teletherapy unit: damage to stored red blood cells after cobalt-60 gamma irradiation.
BACKGROUND Previous publications have documented the damage caused to red blood cells (RBCs) irradiated with X-rays produced by a linear accelerator and with gamma rays derived from a 137Cs source. The biologic effects on RBCs of gamma rays from a 60Co source, however, have not been characterized. STUDY DESIGN AND METHODS This study investigated the effect of 3000 and 4000 cGy on the in vitro...
متن کاملBiological Dosimetry of Co-60 Gamma Irradiation.
Development of radiation technology has resulted in increasing numbers of people working with it. Therefore it has increasingly been important to monitor the radiation in order to ensure public safety. Physical dosimetry plays an important role in monitoring. But a need arise for biological dosimetry where physical dosimetry is absent or its presence is insufficient. In this study Co-60 gamma r...
متن کاملComparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission
Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...
متن کاملHIGH LATITUDE GAMMA RAYS ASSOCIATED WITH VIRGO
A more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 GeV, obtained fromthe EGRET instrument at the Compton Gamma Ray Observatory. The derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with Virgo cluster (over lsr) and average Virgo intensity i...
