Beta rays
|
|
|
Alpha rays
|
|
|
Gamma rays
|

|
X-rays
|
Explanation:
Detailed explanation-1: -Gamma ray has the highest penetrating power whereas alpha ray has the least penetrating power.
Detailed explanation-2: --rays and X-rays have higher penetrating power than -particles or -particles, travel several tens to hundreds of meters in the air (depending on their energy) and gradually lose their energy as they collide with atoms in the air.
Detailed explanation-3: -The great penetrating power of gamma rays stems from the fact that they have no electric charge and thus do not interact with matter as strongly as do charged particles. Because of their penetrating power gamma rays can be used for radiographing holes and defects in metal castings and other structural parts.
