True or False: Radioactive material gives off radiation no matter where it is.

True or False: Radioactive material gives off radiation no matter where it is.

• A. True
• B. False
• C. Only when heated
• D. Only when exposed to light

Answer: (A)

Radioactive decay drives emission of radiation, and that process happens on its own, regardless of where the material is located. The nuclei are unstable, so they release energy and particles as they transform, whether you move the material to a different room, outdoors, or into a container. Location doesn’t stop the decay, but it does affect how much radiation you might be exposed to or detect, because shielding, distance, and geometry influence attenuation and dose. So the statement is true. Heating or exposing the material to light doesn’t switch the emission on or off—radioactivity is not driven by heat or light, but by the intrinsic instability of the nuclei.
