Radiation Damage to Amine Extractants, (I)

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 ...

Pion radiation damage in InGaAs p-i-n photodiodes

Fully packaged InGaAs p-i-n photodiodes for use in CMS Tracker optical digital timing and control links have been irradiated at room temperature with 330MeV positive pions. Measurements of the leakage current and photocurrent response were made in-situ for pion fluences up to 3.9x10π/cm. The leakage current increases from <1nA to 40μA at 5V reverse bias and the photocurrent for 100μW incident o...
