PPT-Gamma-rays and Nuclear Physics

121120 1 Gammarays are ideal probes of a subset of the radioactive isotopes produced in astrophysical transients A number of new gammaray missions are being developed ASCENT COSI LOX AMEGO that will improve sensitivities by over an order of magnitude allowing us to probe more transients and a broader range of isotopes. Learning Objectives. I must be able to recall when ionising radiation is emitted. . I should be able to describe the three types of ionising radiation.. I might be able to explain the dangers of ionising radiation.. High Energy & Cosmic Ray Research Ctr.. North Bengal University. TeV Neutrinos and Gamma rays from Pulsars/Magnetars. Introduction. The energy spectrum of cosmic rays extends to extremely high energies, values exceeding 10. Wavelength the size of an atom. Frequencies above UV. Uses of X-rays. Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods. . used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye.
