Suppose that you get rich by discovering a new deposit of uranium in Exercise 19.6 and that you decide to go into the uranium exploration business full time. You buy an airplane and equip it with a very expensive radiation detector that can look down on the ground from above. What sort of radiation does the detector on the plane need to detect so that you can y the plane at a height of 1000 m and still detect the undiscovered uranium?

Exercise 19.6

Suppose that you decide to go exploring for uranium ore in the desert equipped with a Geiger counter mounted on the back of an SUV. After driving in the desert for an hour, the Geiger counter starts to click violently, and you believe that you have discovered a new deposit of uranium ore. What sort of radiation is the Geiger counter picking up from the uranium ore?
