Radiation from a point source follows an inverse-squarelaw
Chapter 13, Problem 29(choose chapter or problem)
Radiation from a point source follows an inverse-squarelaw in which the amount of radiation received is proportionalto 1>d 2, where d is distance. If a Geiger counterthat is 1 m away from a small source reads 100 countsper minute, what will its reading be 2 m from the source?3 m from it?
