Which property of a radioactive element is exploited to detect radioactivity?

Question

Quizplus · Accepted Answer

The ionizing ability of a radioactive element is exploited to detect its radioactivity. When a radioactive particle passes through a material, it can ionize atoms in that material, creating charged particles which can be detected and measured. This is the basis of many types of radiation detectors, such as Geiger-Müller counters. The charge and mass of a radioactive element are important properties for understanding its behavior, but they are not directly exploited in the detection of its radioactivity.
