of her body is carbon? Given the number ratio of 14Cl2C is 1.2 x 10-12, half-life 5730 years and Avagadro's number is 6.023 x 10D. The range of a 3 Me V a particle in silicon (Asi = 28, Psi= 2.33 x is 12.5 J..lm. What is the range of this a particle in gold (AAu = 19.3 x 103 kg m-E. What fraction of a beam of 1 MeV photons will interact in a 1 lead slab if the beam incidents normally on the slab. The linear attenuation coefficient is given as 0.8 cm-1. F. Calculate the maximum voltage of the output pulse produced by collecting a total charge of 106 electrons on a capacitance of 100 pF. Given charge electron is 1.6 x 10-19 C. G. Explain the function of the activator added in trace quantities to inorganic scintillators. H. Define the meaning of 'residence time' as used in the MIRD I. Define briefly the various classes of lasers for controlling their hazards. J. Define the term that is used to quantify radiation doses due to non-ionizing radiations. of 14 C is 23 . 10 3 kg m- 3 ) 197, PAu = 3 )? cm thick of of an many approach. 1
