Rounding: significant numbers.

The Sievert is the SI-unit of the dose equivalent of ionizing radiation. The older unit rem (roentgen equivalent man) is no longer in use.

The absorbed radiation dose (in Gy) is multiplied by a dimensionless weighting factor (quality factor) that describes the biological effectiveness of the radiation to calculate the dose equivalent (in Sv). For a calculation of the dose equivalent (in sievert, Sv) from the radioactivity in becquerel (Bq) you need conversion factors that depend on the isotope and the kind of contact (e. g. inhalation).

Usage of the dose equivalent converter:
Type the value to convert into the field, behind which you find the unit. Click on any empty space in the window or on the "calculate" button. Read the result in the other fields. Use the "reset" button to reset your calculation. Move the mouse over a unit or click on it to read its full name.

Example: How many sievert correspond to an equivalent dose of 22 millirem ? Type "22" into the field behind which "mrem" is written. Click on any empty space in the window or on the "calculate" button. Read the result in the other fields. (e.g. 220 µSv).

Remarks:
- Please note the remarks about the representation of numbers..
- There is no warranty for the calculation. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.
