Inverse square law for Nuclear radiation from GM Counter
COMMENTS
Geiger Counter Experiment 4
In this experiment we will examine the Inverse Square Law. The law states that the intensity of radiation is inversely proportional to the square of the distance from the source. I used a CS-137 10 uCi source for this experiment. I started measuring CPM counts at 16 centimeters from the source using the side of the GM tube.

Experiment #1: The Inverse Squares
As the radiation moves farther from the source, it becomes less intense. With this information, we also know that the inverse square law applies accurately only when the distance from the source is several times greater than the diameter of the detector. In this experiment the distances are 8 cm, 16 cm, 24 cm, and 32 cm from the source.

The Geiger-Müller counter (commonly called a GM counter or simply a Geiger tube) is one of the oldest and widely used nuclear radiation detectors. It consists of a metallic tube with a thin wire mounted along its axis. The wire is insulated from the tube using a ceramic feed-through (Fig. 1.1). The central wire (anode) is kept at a positive ...

Gamma radiation: inverse square law
Demonstration: gamma radiation is part of the electromagnetic spectrum. It is not absorbed by the air, but its intensity decreases because it spreads out. Therefore, the intensity varies with the inverse square of distance: it follows an inverse square law. You can show this in the laboratory and use it as evidence to support the fact that gamma radiation is a part of the electromagnetic spectrum.
