Beta particle emission can be electron emission (beta minus) or positron emission (beta plus). The daughter products are usually what?

• A. Radioactive and lead to a decay chain
• B. Always stable immediately
• C. Convert to neutrons only
• D. Do not contribute to shielding concerns

Answer: (A)

Beta decay changes the proton count without changing the total number of nucleons, so the resulting nucleus often isn’t the final stable form. The daughter is typically still radioactive and will undergo further decays, creating a decay chain (or decay series) until a stable nucleus is reached. This happens whether the decay is beta minus (neutron to proton, Z increases by 1) or beta plus (proton to neutron, Z decreases by 1). It’s not about converting everything to neutrons, nor about eliminating radioactivity or shielding concerns—the common outcome is continued radioactivity through a chain of decays.
