Victor is using his Geiger-counter to record the amount of radiation that is leaking into the soil from a nearby nuclear disposal site. This radiation decreases by the square of the distance from the source. If he starts measurements 100 m from the disposal site how close will he need to stand if he hopes to measure soil with 4 times the radiation?

According to inverse square proportionality, measuring 4 times more radiation will require Victor to _ his distance. Victor will need to stand _ m from the disposal site.
