چکیده
OBJECTIVES: After completing this module you will be able to: Explain why ionizing radiation has little effect on metals and their mechanical properties. but creates significant damage in non-metals. 4.2 a) Describe the damage created in metals by fast neutrons. b) Explain how this damage affects: strength, hardness and ductility. 4.3 Explain why elevated operating temperatures reduce the effects of fast neutron damage. 4.4 State the affect of thennal neutrons on the properties of metals. 4.5 Describe the effect of radiation on: (a) oBs and greases, (b) plastics and rubbers, 4.6 a) Explain how radiation affects the structural integrity and shielding properties of concrete, b) State how damage to concrete biological shielding is avoided.

Oxidative membrane damage and its involvement in gamma radiation-induced apoptotic cell death.
Background: Recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. These findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. The present study was aimed to gain deeper ins...
متن کاملQuantitation of genome damage and transcriptional profile of DNA damage response genes in human peripheral blood mononuclear cells exposed in vitro to low doses of neutron radiation
Background: Humans are exposed to ionizing radiation from different sources that include natural, occupational, medical, accidental exposures. Evaluation of the effect of low level of neutron exposure to human cells in vitro has important implications to human health. Attempts were made to measure genome damage, transcriptional profile of DNA damage response and repair genes in peripheral blood...
متن کاملReduced DNA damage in tumor spheroids compared to monolayer cultures exposed to ionizing radiation
Background: Several cell lines when cultured under proper condition can form three dimensional structures called multicellular tumor spheroids. Tumor spheroids are valuable in vitro models for studying physical and biological behavior of real tumors. A number of previous studies using a variety of techniques have shown no relationship between radiosensitivity and DNA strand breaks in monolayer ...
متن کاملCombined Effects of 528 Hz Sound and X-ray in Peripheral Blood Lymphocytes
Introduction: Radiotherapy is still one of the main options for cancer treatment but it is in association with damage to normal cells as well as the tumor cells. To reduce the injury in normal cells we have evaluated the effect of 528 hertz sound after X irradiation in peripheral blood lymphocytes. Materials and Methods: in this study, peripheral blood was o...
