The Geiger counter has a cylindrical detecting volume of length 3.4 cm and diameter 1.4 cm. Lisa estimates the number of events that her body would detect, for a measured background rate of 14.4 cpm, by regarding its volume as a collection of many such tubes. She treats her volume as a box of height 157 cm, width 35 cm, and depth 17 cm. How many external radiation events does it register per minute? HINT: By what factor is Lisa's body larger than the Geiger counter?
