Becquerel a gram of potassium is 30 Bq. The following table shows radiation quantities in SI and non-SI units. Becquerel The becquerel (; symbol: Bq) is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The becquerel is therefore equivalent to an inverse second, s. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Curie in 1903 for their work in discovering radioactivity. As with every International System of Units (SI) unit named for a
Radioactivity (song) the original does not offer a value judgement on the safety of radioactivity, the 1991 version drops all references to radio and incorporates additional lyrics with a pointed anti-nuclear theme, remaking the central lyrical hook as "stop radioactivity" and also referring to "contaminated population" and mentioning by name Chernobyl, Harrisburg (Three Mile Island), Sellafield and Hiroshima. "Radioactivity" has remained a regular part of Kraftwerk's live sets over the years. On its original performances in 1976, the band tried out an experimental light-beam operated "percussion cage", where Wolfgang Flür attempted to trigger electronic drum sounds by interrupting light beams using arm
