Answer : The increasing order of the types of nuclear radiation from lowest to highest energy will be,
Alpha rays < Beta rays < Gamma rays
Explanation :
Nuclear radiation : It is defined as the energy of the particles that are releases from the radioactive elements.
There are three types of particles which are, alpha, beta and gamma particles.
Penetration power : It is the movement of rays or the particles through an object.
The energy of the particles depends on their penetration power.
Hence, the increasing order of the types of nuclear radiation from lowest to highest energy will be,
Alpha rays < Beta rays < Gamma rays
