abstract:In nuclear sciences and technologies, "activity" is the SI quantity related to the phenomenon of natural and artificial radioactivity. The SI unit of "activity" is becquerel, Bq, while that of "specific activity" is Bq/kg.
The new standards specify that U.S. laws apply to Secret Service personnel when traveling, rendering invalid the excuse that specificactivity is legal in the foreign country, the officials said.
