Term: Alpha Ray

Description:

Alpha ray refers to a stream of positively charged particles, known as alpha particles, emitted during the radioactive decay of certain atomic nuclei. Alpha particles consist of two protons and two neutrons, making them the heaviest and slowest ionizing radiation type. They possess low penetrating power and can be easily stopped by a sheet of paper or a few centimeters of air. Alpha rays are primarily used in scientific research, as well as in various industrial and medical applications.

Sample Sentences:

1. During the experiment, scientists detected alpha rays emitted by the decaying radioactive material.
2. Alpha particles, or alpha rays, are commonly used in smoke detectors as their ionizing properties make them efficient in identifying smoke particles.
3. Protective clothing and shielding are necessary precautions when working with alpha rays in the laboratory.
4. The monitoring system alerted the workers about the presence of alpha rays in the vicinity, prompting an evacuation.
