vCalc.vRadiation Dose

This radiation dosage conversion equation converts the input measure of radiation dosage into other chosen units of radiation dosage.


Radiation Dose is a measure of absorbed dose, specific energy (imparted), and kerma.1 The radiation dose is measured as a unit of ionizing radiation and is defined as the absorption of a quantity of energy by a mass.

The units of radiation dose supported by vCalc for conversions are:

  • Gy - the gray (defined as the absorption of 1 J of radiation energy by 1 kg of mass)
  • Sv - the sievert (a derived unit of ionizing radiation in the SI system)
  • rd - the deprecated unit, correctly the rad
  • rem - roentgen equivalent man

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 radiation dose 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 Gy as your input radiation dose unit, the display will show a resultant 450 Gy output.  If you then select rem as your output units, the output is automatically converted to 45000 rem.
