"Cameron would use cobalt-60 (which releases gamma rays), Billy would use carbon-14, and Isabelle would use uranium-238."

Reason: Co-60 is used as a gamma source for cancer radiotherapy, C-14 is used for radiocarbon dating of archaeological (organic) materials, and U-238 (U–Pb dating) is used to date geological layers over very long timescales.
