Radiation Damage to TBP/Kerosene Solvent

RADiATiON DAMAGE TO MATERIALS

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 effec...

Radiation Damage to Thoracic Tissues.

Radiotherapy to the thorax in conventional dosage appears to be capable of causing damage to any of the tissues in the thoracic wall or within the thoracic cavity. Since the earliest days of x-ray treatment radiation changes in the skin have been such an everyday problem that they scarcely warrant discussion here except to note that with the advent of new radiotherapeutic techniques they are be...

Radiation track and DNA damage

Reduced 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 ...

Sensitivity of the Retina to Radiation Damage

Exposure of the retina of the rhesus monkey to visible and infrared radiation from CW optical sources like the Sun, xenon lamps, etc. produces small lesions or scotomata which may be classified as thermal or photochemical, depending on the wavelength and duration of exposure. The action spectrum for the production of retinal lesions has been determined for eight monochromatic laser wavelengths ...
