It is not clear what is meant by 'beta'. Please rephrase it in a new question. It's pretty obvious this question is about radioactivity and the beta particles produced by that. In fact beta particles are not the least penetrating. It is the alpha particles that penetrate least. That's because they interact easily with atomic nuclei. Atomic nuclei are positively charged, like alpha particles, causing strong repulsion.
Beta particles are often used in smoke detectors.
The minimum protection against exposure to beta particles is a thin sheet of metal or plastic. Beta particles are classified as subatomic particles.
alpha particles would have twice as many beta particles
Gamma rays are more penetrating than alpha and beta particles.
It's not possible to change beta particles to alpha particles or vice versa; they're two very different things produced by different processes. Beta particles can be either electrons or they can be positrons, which are anti-electrons. Alpha particles are helium-4 nuclei, which are composed of a pair of protons and a pair of neutrons. Beta particles are produced in beta decay (one in each type), and alpha particles are produced in alpha decay. Both of these types of nuclear decay release particulate radiation. Links can be found below to check things out.
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
There is no such thing as delta particles in nuclear decay.
ionization of air which triggers condensation.
The reaction is:Pu-239-------2n,gamma--------→Pu-241------beta---------→Am-241

Beta particles are not stopped by a paper sheet.
Low energy beta particles, say, from tritium, are called soft beta particles.
alpha particles=8 and beta particles=6
Thin sheet or plastic may prevent beta particles.
Beta particles are often used in smoke detectors.
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
