If you have a material that emitts Beta particles there is nothing that will effect that process. However, once the Betas are emitted you can block them with Aluminum or most anything else. How many you block will depend on how fast the Betas are going and how thick your blocking material is.
When magnesium-28 undergoes beta decay, a neutron is converted into a proton, resulting in the formation of an aluminum-28 nucleus. The mass number remains the same at 28, as the total number of protons and neutrons is conserved during beta decay.
The energy of beta particles in beta decay is not fixed because it depends on the specific isotope and decay process involved. Beta decay can produce high-energy electrons and positrons through beta minus and beta plus decay, respectively. The energy of the beta particles is determined by the energy released during the decay process.
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
Aluminum-28 decays into stable silicon-28. Al-28's decay can be thought of in this way: One of the neutrons of Al-28 nucleus decays into an electron and a proton (the sum being electrically neutral). The high-speed electron is the beta particle that is net-released from the atom but the proton stays behind in the nucleus. But now, the number of protons in the nucleus has increased from 13 (in Al-28) to 14 (Si-28). So from this beta decay, an atom of unstable Al-28 lets fly a beta particle (high speed electron) but moves up one in the periodic table (to Si-28).

aluminum-28
There are two types of beta decay, and they are beta plus (beta +) decay and beta minus (beta -) decay. A post already exists on beta decay, and a link to that related question can be found below.
The energy of beta particles in beta decay is not fixed because it depends on the specific isotope and decay process involved. Beta decay can produce high-energy electrons and positrons through beta minus and beta plus decay, respectively. The energy of the beta particles is determined by the energy released during the decay process.
The equation for alpha decay of thorium-228 is 228Th -> 224Ra + 4He, where thorium-228 decays into radium-224 by emitting an alpha particle (helium nucleus). The equation for beta decay of aluminum-28 is 28Al -> 28Si + e + v, where aluminum-28 decays into silicon-28 by emitting a beta particle (electron) and an antineutrino.
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
beta
Beta decay is a property of atoms not molecules.
Beta decay is stopped by shielding materials such as lead or concrete, which can absorb the emitted beta particles. The higher the density of the material, the better it is at stopping beta particles. The thickness of the shielding needed depends on the energy of the beta particles being emitted.
During beta decay, a beta particle (an electron or positron) is emitted, along with an antineutrino or neutrino, depending on whether it's beta-minus or beta-plus decay, respectively. Beta decay involves the transmutation of a neutron into a proton within the nucleus, releasing the beta particle in the process.

From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
