Description

 • Radioactivity has the dimension length squared mass per time. The SI composite unit of radioactivity is the kilogram meter squared per second.
 • Maple knows the units of radioactivity listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes becquerel Bq SI * becquerels SI curie Ci radiation * curies SI rutherford Rd radiation * rutherfords SI

 An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, becquerel[SI] or Ci[radiation]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, becquerel or Ci.
 The units of radioactivity are defined as follows.
 A becquerel is defined as a radionuclide decay per second.
 A curie is defined as $3.7×{10}^{10}$ radionuclide decays per second.
 A rutherford is defined as $1.×{10}^{6}$ radionuclide decays per second.
