If a sample emits 1000 counts per second when the detector is 1 meter from the sample, how many counts per second would be observed when the detector is 2 meters from the sample?

Can you answer this please !
Answered by Gina
Doubling the distance will result in a count of (1/2)^2= 1/4 the original
count. 1/4 of 1000 = 250 counts per minute.
