If I passed through a radiation detector carrying Polonium 210 stored in a glass vial in my pocket, would the detector alarm go off? Select one:

A. Yes - Polonium 210 can penetrate the skin very easily.
B. Yes - Polonium 210 has a very short half-life.
C. Yes - Polonium 210 emits gamma radiation.
D. No - Polonium 210 emits alpha radiation.
E. No - Polonium 210 emits beta radiation.

Polonium-210 emits alpha radiation, which can be stopped by small barriers, so it would not set off a radiation detector if stored in a glass vial. However, it can be dangerous if ingested or inhaled.

Explanation:

The correct answer to your question is D. No - Polonium 210 emits alpha radiation. This is because polonium-210 undergoes alpha decay, which is the emission of an alpha particle from the nucleus. Alpha particles have strong ionizing potential, but they can be stopped by very thin shielding, such as a layer of skin or paper. Therefore, polonium-210 stored in a glass vial, which would provide even more shielding, would likely not set off a radiation detector. However, it's important to note that while alpha particles may not be dangerous externally due to their limited penetration, they are incredibly hazardous if ingested or inhaled. Keeping Polonium 210 in your pocket is therefore a risky move due to potential contamination risks.
