← ScienceWhich consequence results when uranium ore contamination increases radon emanation?
A)Lung cancer risk elevates sharply✓
B)Half-life shortens dramatically
C)Shielding effectiveness is greatly reduced
D)Ore processing becomes supercritical
💡 Explanation
Increased uranium-238 leads to higher radon gas production via alpha decay, and therefore results in increases in radiation-induced lung cancer, rather than affecting half-life because decay constant for U-238 remains unchanged.
