What does terabecquerel measure?

The terabecquerel measures radioactive activity indicating the number of nuclear decays per second, equal to 10^12 becquerels.

How is a kilocurie defined?

A kilocurie is a unit of radioactivity equal to 1,000 curies, with one curie corresponding to 3.7 × 10^10 decays per second, so 1 kCi equals 3.7 × 10^13 becquerels.

Why convert TBq to kCi?

Converting from terabecquerel to kilocurie helps express large radioactive activity values in units more common in industrial and regulatory environments.
