Description
Introduction to natural and artificial radionuclide sources in the atmosphere Cosmogenic radionuclides (eg 7Be, 22Na...) and 210Pb from terrestrial origin and their use in global atmospheric models Radioactive aerosols and their diameter, AMAD value, penetration to the lugs, dose assessments Instruments for collecting radioactive nuclides in the atmosphere, collecting substrates, instruments for measuring the air filtes Long range transport of radionuclides in the atmosphere, example of Chernobyl and Fukushima accident Specific measurements in the region of Thessaloniki, Greece and Milano, Italy after the Fukushima accident ...FURTHERMORE, a short introduction how we measure in the same air filters trace elements or heavy metals by nuclear techniques eg. XRF and INAA.
How can we fast characterize an area if it is high contaminated or not? What about the remediation of large area or old uranium mines, oil mines etc? How can we take a fast decision of an area if it must be abounded or not? Emergency response in case of nuclear accidents, orphan sources, transportation of nuclear material etc In-situ method is a rapid and low cost method. Examples of in-situ instruments and examples of in-situ measurement technique in action. Advantages and disadvantages of in-situ measurement technique. Lectures will include short exercises using portable gamma ray detector with GPS.
