Why beta particles are used rather than alpha particles or gamma rays?

Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue, but also the lower the penetrating power of the radiation.

Can you deflect gamma radiation in a way similar to alpha and beta particles?

No, it is not possible to deflect gamma radiation in a way similar to alpha and beta particles, using the electric or magnetic field because they are neutral and hence do not deflected under the action of electric or magnetic field.

Do beta particles have more energy than alpha particles?

Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue. Beta particles are much smaller than alpha particles and therefore, have much less ionizing power (less ability to damage tissue), but their small size gives them much greater penetration power.

Do gamma rays have the same energy as beta particles?

Gamma rays (γ) are weightless packets of energy called photons. Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

Why are beta particles stopped by aluminium?

Beta particles travel faster than alpha particles and carry less charge, so they interact less readily with the material through which they pass. They can be stopped by a few millimetres of aluminium. Gamma rays are highly penetrative. Many centimetres of aluminium would be required to absorb energetic gamma rays.

Can beta particles penetrate tissue?

β-Radiation does not penetrate tissues deeply, and its use is therefore limited to superficial small lesions. Seventy-five percent of β-rays are absorbed by the first 2 mm of tissue and much of the remainder by the next 1 mm.

Is it possible to deflect γ radiations in a way similar to α and β particles using the electric or magnetic field give reasons?

Give reasons. No, it is not possible to deflect gamma radiation in a way similar to alpha and beta particles, using the electric or magnetic field because they are neutral and hence do not deflected under the action of electric or magnetic field.

Why does radiation C deflect more than a?

(ii) The deflection of radiation C (or β-particle) is more than the radiation A (or α-particle) because β-particles have less mass than α-particles.

What is the difference between alpha beta and gamma?

Alpha is a positively charged particle, beta is negatively or positively charged. On the contrary, gamma particle has no charge and so is neutral. Basically, radioactive decay is a process in which unstable atomic nuclei releases energy in order to get stabilized.

Can gamma pass through aluminium?

Gamma radiation can travel through most substances. Alpha particles can’t go through paper, but beta particles and gamma rays can. When the three types of radiation hit the aluminium, only the gamma rays get through. Beta particles can get through paper but the aluminium stops them.
