`"Radioactive Activity"_"(converted)" = `

This radioactivity conversion equation converts the input measure of radioactivity into other chosen units of radioactivity. Ionizing radiation includes alpha particles, beta particles, gamma rays and conversion electrons.


Radioactivity is a measure of the stochastic process by which a nucleus of an unstable atom loses energy by emitting ionizing radiation.

The units of radioactivity supported by vCalc for conversions are:

  • Bq - the becquerel, defined as the activity of a quantity of radioactive material in which one nucleus decays per second
  • Ci - the Curiedefined as 3.7 × 1010 decays per second

To perform conversion, enter the numeric number of units you want to convert and pull-down the menu to select the units associated with your input value.

The results will be displayed in the default radioactivity units and you can pull-down the units selection menu to change the output units to your desired converted units.

For example: if you enter 450 and leave the default input units as Bq as your input radiation dose unit, the display will show a resultant 450 Bq output.  If you then select Ci as your output units, the output is automatically converted to 0.00000001216216216216216 Ci.
