Question

Which list of nuclear emissions is arranged in order from the greatest penetrating power to the least penetrating power?
(1) alpha particle, beta particle, gamma ray
(2) alpha particle, gamma ray, beta particle
(3) gamma ray, alpha particle, beta particle
(4) gamma ray, beta particle, alpha particle

Answer 1

Answer:

(4) gamma ray, beta particle, alpha particle.

Explanation:

Penetration power is the capacity of a radiation to pass through any matter.

the penetration power is inversely proportional to the mass of particles or radiation.

Out of the given three rays, gamma rays are lightest then beta and then alpha.

Thus penetration power of gamma rays is highest.

Then beta particles

Then alpha particles.

Answer 2

The list of nuclear emissions is arranged in order from the greatest penetrating power to the least penetrating power is  gamma ray, beta particle, alpha particle.

What is nuclear emission?

Nuclear emission is the emission of nuclear energy by the chemicals produced in factories.

Nuclear reactors do not produce air pollution.

Thus, the correct option is (4) gamma ray, beta particle, alpha particle.
