Beta particles are made of a single electron, therefore are much smaller than the alpha particle, which is made of 2 protons and 2 neutrons

Which penetrates farthest in an object Alpha particle or beta?
Not much. A sheet of paper will stop it. The alpha particle is two protons and two neutrons - a helium-4 nucleus. As radiation goes, it's big and fat, and it will "run into" stuff even if it's just flying through air. Depending on its energy, it can penetrate air, but not more than a few inches.
What can stop beta radiation particles?
Certain types of plastic can be used to form an efficient barrier for dealing with high-energy beta radiation. Many acrylic sheets effectively protect individuals from exposure to beta radiation. While lead is a good standby, in some cases, lead is ineffective in stopping beta particles because it can produce secondary radiation when passing through elements with a high atomic number and density.
How strong beta particles?
Beta particles are typically one of the weakest radiation (alpha has the most energy). Ranging from 15 KeV up to 2 MeV. But because it is so small (1/6400 the size of an alpha particle) it can penetrate through the air and the skin. A few layers of aluminum will stop it (while alpha will only go a few inches through air, or just to the first layer of the skin).
What is a good stopper of ionizing radiation?
If by ionising radiation you mean alpha radiation (the most ionising out of alpha, beta and gamma radiation) then about a millimetre of paper would stop it. alpha radiation ionises the molecules of anything it reaches, but can pass through very few things due to its immense ionising power. This includes human tissue, but in all honesty, a large dose of alpha radiation wouldn't do human tissue alot of good. In short, almost any material can stop ionising radiation.
Which of the following represents the ranking in increasing order of range in air of alpha beta and gamma rays?
alpha (helium nucleus, big and heavy, stopped by air in a very short distance)beta (high speed electrons or positrons - very light particle, travels a few inches in air)gamma (a form of electromagnetic radiation from the high energy end of the spectrum, very hard to stop)
What can be blocked with a sheet of paper?
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
What material could possibly stop alpha gamma and beta radiation?
paper and flesh
Why is the nuclear reactor surrounded by a thick concrete layer?
To stop radiation leaking out. Alpha and Beta types of radiation will be stopped by the concrete

How strong are beta particles?

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 can stop both alpha and gamma waves?
First of all its a Alpha particle, and a gamma wave, Paper can stop alpha, and nothing can stop gamma, but it is slowed down by lead, and concrete.
Why is it harder to stop a 4 person bobsled?
The more weight the harder to stop.
What are the 3 types of radiation and their relative strength?
Alpha - a helium nucleolus, energetic but easily stopped. Beta - an electron, any metal foil will stop Gamma - hard radiation (photons), hard to shield from. These were just the first 3 known; now have neutrinos, neutrons, "name a particle"
