115. (b) arouse concern about the risks connected with exposure to radiation (Because the second para talks about the hazards of the radiation, the third para is concerned with the arthritis patients due to X rays and the fourth para tells about author's concern regarding regulatory efforts)
116. (c) Cosmic rays, radioactive potassium in bones, radioactive carbon in tissues (Because the first para in the starting tells about the three natural sources of radioactive material)
117. (d) II and III only (Becuase the second para tells about UNSC's report of 1958 which tells that smallest amounts of radiation can also be harmful and then the third para gives the example of the hazards of using X ray)
118. (d) Why is exposure to the fallout from weapons testing considered by some to be more hazardous than exposure to X rays (Because the second para tells that "hazards from this source are not as great as those from weapons test fallout, since strontium 90 and carbon 14 become incorporated into the body")
119. (c) have the effect of increasing by 1 percent the cases of serious genetic defects (Because the last line of the third para tells so)
120. (d) regulatory efforts have been balked by disputes, confusion, and bureaucratic delays (Because the resignation by the chairperson is the consequence of the poor regulatory efforts)

122. (d) Humans can tolerate a certain amount of radiation (Because the first para tells that "substances in the human body, such as radioactive potassium in bone and radioactive carbon in tissues")
