which is highest penetrating power?
A) gamma ray
B) beta decay
C) alpha decay
D) neutron
The correct answer is:
A) Gamma ray
Gamma rays have the highest penetrating power among the options listed. They are a type of electromagnetic radiation, similar to X-rays, but with even higher energy and shorter wavelengths. Gamma rays can pe*****te thick layers of material, including lead and concrete, and can travel long distances through air and other materials.
The penetrating power of the options listed, from highest to lowest, is:
1. Gamma ray
2. Beta decay (beta particles)
3. Neutron
4. Alpha decay (alpha particles)
Alpha particles, which are high-energy helium nuclei, have a relatively low penetrating power and can be stopped by a sheet of paper or a few centimeters of air. Beta particles, which are high-energy electrons, have a higher penetrating power than alpha particles but are still less penetrating than gamma rays. Neutrons, which are neutral particles, have a moderate penetrating power and can travel through some materials, but are less penetrating than gamma rays.
