← ScienceWhich risk increases when a medical iodine-131 shipment's shielding is compromised?
A)Increased background radiation exposure✓
B)Accelerated radioisotope decay reactions
C)Material alteration reduces stability
D)Radioisotope half-life becomes significantly shorter
💡 Explanation
Increased background radiation exposure results because Compton scattering increases as shielding is compromised, releasing a higher-energy photon flux, rather than affecting the nuclear isotope activity, therefore the sample decays at its predetermined rate, regardless.
