Question

Tabulate the following statements as applicable to each of the harmful radiations emitted by natural radio active substances and other radiations (They are electromagnetic radiation. They have high penetrating power. They are electrons. They contain neutrons)

Answer 1

Your question is unclear

Answer 2

Radiations:

They are electromagnetic radiation = Gamma rays

They have high penetrating power = Gamma rays

They are electrons = Beta rays

They contain neutrons = Alpha rays

Alpha rays:

• This ray has positively charged particles.
• The nucleus in the alpha particles as two protons and two neutrons.
• They have least penetration power and more ionisation power.

Beta rays:

• This ray has negatively charged particles.
• This ray is electrons in high speed.
• They have more penetration power than alpha rays and lease ionisation power.

Gamma rays:

• This ray has the highest penetration power and high frequency.
• This ray has the least ionisation power.
• It has high amount of energy.
