Background radiation refers to the continuous low-level ionizing radiation present in the environment from natural and human-made sources. It includes cosmic rays, radioactive elements in soil, rocks, and buildings, as well as medical procedures, nuclear testing, and industrial activities.
The Geiger-Muller (GM) tube, also known as a Geiger counter, is a radiation detection device that can demonstrate the nature of observing the count rate of radioactive disintegration. It works based on the principles of ionization caused by radioactive particles. Here’s how it demonstrates this nature:
Conversion of a radioactive particle’s energy into an electrical pulse when it interacts with gas molecules in a Geiger-Muller tube.
Increasing the strength of the electrical pulse generated by ionization for easier detection.
The random and spontaneous process by which unstable atomic nuclei emit particles or energy to attain stability
The random and spontaneous process by which unstable atomic nuclei emit particles or energy to attain stability.
Display or sound cues in a Geiger counter that signal the detection of radioactive particles, providing observable evidence of radioactivity.
