D. What is the typical background radiation weare exposed to? What additional exposure would we get from a chestx-ray? A CT scan of the torso? A coast-to-coast flight? A year ofliving in Denver, CO? Approximate or representative values aresufficient.
Please stay within the same unit system (i.e.,choose either Sievert or rem) for easier comparison in (F).
E. Before flat-screen TV sets becamewidespread, color TV sets used huge cathode ray tubes (CRT). Togenerate TV images with sufficient brightness, the electron beamwas accelerated with an appreciably high voltage. What were typicalacceleration voltages in those TV sets? Would they represent anx-ray hazard? Provide a reason for your answer!
Note: Provide the sources for your answers (D)and (E) as well!
Note also: In (E), a government mandate thatthe x-ray dose had to remain below allowed limits isnot a valid reason, because a government mandateis not an engineering solution -- not by a far shot.
