What would the radiation intensity be if the detector was 30.6 meters from the source?
A radiation detector which is located 6.29 meters from a radiation originator indicates a radiation intensity of 311 mCi (millicuries). What would...
The detected radiation is inversely symmetrical to the square of the distance from the source to the detector. Hence the answer is:
(311 mCi)*(6.29/30.6)^2 = 13.1 mCi
