(a) How can you separate the radiation emitted from a radioactive source into components? (b)Explain the radiations according to their penetrating abilities. (c) What are the values of the radiation weighting factors for x - ray at all energies and for neutrons at 2MeV ? (d) Write three examples for man-made radiation sources. (e) PET (positron emission tomography) gives an accurate picture of an area in the body. Explain how it appears. (f) A parent isotope has a half-life t1/2=104 years =3.15×1011s. It decays through a series of radioactive daughters to a final stable isotope. At t=0 it has 1020 parent nuclei. What is the activity (decay/second) of the parent isotope at t=0?(1Ci=3.7×1010Bq)
