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
Notebook paper is not able to stop alpha, beta, or gamma radiation due to its thinness and composition. These types of radiation can easily pass through materials like paper.
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.
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.
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).
Alpha particles, which are relatively large and positively charged, can be stopped by a few centimeters of air or a sheet of paper. Typically, a thickness of just 0.1 mm (100 micrometers) of paper is sufficient to completely halt an alpha particle. This is because alpha particles have low penetration power compared to other types of radiation, such as beta particles or gamma rays.
paper and flesh
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.

To stop radiation leaking out. Alpha and Beta types of radiation will be stopped by the concrete

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"

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.
The more weight the harder to stop.
