bekrell
Usage examples
  • Bekrell, tähis Bq, on SI-süsteemi mõõtühik radioaktiivse aine aktiivsuse mõõtmiseks. Üks bekrell vastab ühele radioaktiivsele lagunemisele sekundis. Kuna 1 Bq on väga väike aktiivsuse tase, mistõttu kasutatakse sageli suuremaid kordseid, nt megabekrelli (MBq), gigabekrelli (GBq) või terabekrelli (TBq).

Usage examples
  • 1 Bq = 1 s-1.
becquerel
Usage examples
  • The becquerel (symbol Bq) is the SI unit of measurement for the activity of a radioactive substance. One becquerel corresponds to one radioactive decay per second. Since 1 Bq is a very small level of activity, larger multiples are often used, such as megabecquerel (MBq), gigabecquerel (GBq), or terabecquerel (TBq).
