← ScienceWhich consequence results when a Strontium-90 source's sealed container fractures?
A)Enhanced probability of chain reaction
B)Reduced detection of alpha particles
C)Increased beta radiation exposure✓
D)Diminished release radon daughter isotopes
💡 Explanation
Fracture exposes the environment to the isotope; the increased beta radiation exposure occurs because radioactive decay yields high energy beta particles. Therefore environmental contamination rises due to beta emission, rather than alpha or radon release, which are not strontium decay products.
