Short: Turbocalc: calculate decaying constant Author: Tapani Hoyssa (thoyssa@surfeu.fi) Uploader: tapani Hoyssa (thoyssa surfeu fi) Type: misc/sci Requires: TurboCalc Architecture: generic This is the English version of turbocalc sheet "atomactivity" You enter the name of the isotope, its halfing-time T½, and the unit in their proper columns, so you get the decaying constant and it`s unit in their columns. The activity of a piece of matter is got, when the amount of the piece in moles is multiplied with the decaying constant in Becquerels. Result is in Becquerelmoles. One becquerel is one decay per second, or 1/s.
