One of the hazards of nuclear explosion is the generation of 90Sr and its subsequent incorporation in bones. This nuclide has a half-life of 28 years. Suppose one microgram was absorbed by a newborn child, how much 90Sr will remain (in micrograms) in his bones on their 14th birthday? (take √2=1.4) |
