← ScienceWhich consequence results when a medical grade Cobalt-60 source experiences containment breach?
A)Surface water contamination increases acidity
B)Chelation therapy becomes urgently required✓
C)Neutron activation generates secondary emitters
D)Gamma decay products induce local heating
💡 Explanation
Exposure necessitates chelation because radioactive cobalt uptake by the body leads to cellular damage. The primary decay mode in Cobalt-60 releases beta particles and high-energy gamma rays, therefore prompt chelation counters uptake, rather than acidification or neutron release.
