Question 3

A scientist is designing a radiation detector to specifically identify alpha particles emitted from a radioactive source, while minimizing interference from beta and gamma radiation. Which of the following detector characteristics would be most effective for this purpose?

Accepted Answer

B. A very thin window or no window, and a short detection path within the detector. — Alpha particles have very low penetrating power and a short range in matter. Therefore, a detector with a very thin window or no window allows them to enter, and a short detection path is sufficient to capture their energy before they are fully absorbed, effectively distinguishing them from more penetrating beta and gamma radiation. Thick lead shielding is primarily for gamma rays, liquid scintillators are general-purpose but less specific for alpha due to range, and a magnetic field deflects both alpha and beta particles without selective identification based on entry alone.

Answer

A. A thick lead shielding around the detector.

Answer

C. A high-density liquid scintillator.

Answer

D. A strong magnetic field across the detection area.
