Chapter 16, Problem 1TS

Solution

To determine: The reading of the Geiger counter is for 2 meters and 3 meter from the source.

Answer:

Geiger counter reads 50 counts at a distance of 2 meters and 25 counts at a distance of 3 meters.

Explanation:

The reading of the Geiger counter is inversely related to the square of the distance from the source by using the inverse square law. The amount of the radiation is separated into half per extra meter of the distance.

If Geiger counter reads the 100 counts at a distance of 1 meter from the source; as a result, it reads 50 counts at a distance of 2 meters and 25 counts at a distance of 3 meters.

Conclusion:

Therefore, the Geiger counter reads 50 counts at a distance of 2 meters and 25 counts at a distance of 3 meters.
