Radiation Equivalent Dose Converter
Convert equivalent dose units used in radiation protection.
How to Use the Radiation Equivalent Dose Converter
Enter an equivalent dose value, select the source unit and choose the target unit to convert between sievert, millisievert, microsievert and rem.
Practical Example
1 sievert equals 1,000 mSv and 100 rem.
Factors That Affect Equivalent Dose
Equivalent dose depends on absorbed dose and radiation weighting factors. The converter changes units only and does not calculate biological risk.
Frequently Asked Questions
What is a sievert?
The sievert is the SI unit used for equivalent and effective dose.
How many rem are in one sievert?
One sievert equals 100 rem.
Is mSv the same as µSv?
No. One mSv equals 1,000 µSv.
Understanding Equivalent Dose Units
Equivalent dose accounts for absorbed radiation together with a weighting factor for radiation type and is commonly expressed in sieverts or rem. One sievert equals 100 rem, with millisieverts and microsieverts widely used for smaller values.
This is different from absorbed dose measured in gray. Unit conversion does not assess personal risk or exposure safety, so professional guidance and the correct dose quantity are important in medical or radiation-protection contexts.
Technical Context and Conversion Notes
Equivalent dose applies radiation weighting to absorbed dose and is measured in sieverts. 1 Sv = 100 rem; it should not be confused with activity in becquerels or absorbed dose in grays.
