What are the components of natural radiation in order from least to most penetrating?
Alpha particles, which consist of two protons and two neutrons; Beta particles, which consist of one electron; Gamma rays, which is the highest frequency of electromagnetic radiation, has no mass, and is not made up of any subatomic particles. Alpha particles con be stopped by a mere piece of paper; Beta particles can pass through paper but can be stopped by aluminum foil; Gamma rays can pass through paper and aluminum foil, and can only be stopped by lead or concrete.
How would you list alpha partcles beta particles and gamma rays in order of increasing penetrating power?
Alpha particles are the least penetrating, and are not able to pass through a single sheet of paper. Beta particles can penetrate through a sheet of paper, but not a piece of aluminum. Gamma rays can travel through both paper and aluminum and it takes dense material like lead to stop them or reduce their number. Gamma rays are high energy electromagnetic rays.
What form of electromagnetic radiation passes through skin but not bone?
Alpha radiation, it's force is too weak to even penetrate the outer layer of dead skin. Beta and Gamma radiation can pass through, Beta has trouble passing through clothes whereas Gamma is able to go straight through the body.
What can alpha particles can pass through?
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
Why can beta particles and gamma rays pass through paper and lead?
Depends on how thick the lead is, but beta particles in general don't travel all that far. Of the three types of radiation, gamma (high energy photons) penetrate the most, alpha (helium nuclei) the least, and beta (electrons or positrons) somewhere in the middle. Since most lead jackets stop gamma you can be pretty sure that the lead jackets they use around x-ray machines will stop beta particles.
How far will beta travel?
That depends on the energy of the beta particles and the medium they are passing through. In air beta can travel several inches to several feet. Beta cannot pass through a single layer of aluminum foil.

Explain why beta and gamma particles can easily enter your body?
Beta particles are very small and gamma rays are insubstantial so they can easily pass between or through the atoms of your skin and into your body.
Can beta rays pass through 1cm thick aluminium foil?
No, it cannot. Alpha particles can be stopped using aluminum foil. Beta particles (electrons) posses higher kinetic energy and have smaller cross section. Lead is widely used to stop beta particles as well as gamma particles. Gamma particles are basically high energy photons which are extremely dangerous for alive creatures. Extra precaution must be taken when you are working with such radiation.
Why alpha particles tend to produce more ions than beta particles or gamma rays when they pass through matter?
Alpha particles have a high ionizing power beacaue they have a great linear transfer of energy.
Why beta and alpha particles deflected when they pass the magnetic field?
Alpha and beta particles are deflected by a magnetic field because they have charge and, as such, are affected by the electromagnetic interaction or force.
What form of electromagnetic radiation passes through skin but not bone?
Alpha radiation, it's force is too weak to even penetrate the outer layer of dead skin. Beta and Gamma radiation can pass through, Beta has trouble passing through clothes whereas Gamma is able to go straight through the body.
Why do alpha and beta particles cause more damage if they are inside the?
Because alpha and beta particles do not have enough power to pass into the body, but they do more damage than gamma rays once they are inside the body.
Is a sheet of aluminum opaque?
Aluminum (or aluminium) is opaque. Light does not pass through it.
What can alpha particles can pass through?
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
What is the process by which tiny particles can pass through the cell membrane?
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
