What does one REM represent in terms of Sieverts?

1. 0.01 Sv

2. 0.1 Sv

3. 1 Sv

4. 10 Sv

The correct answer is: 0.01 Sv

One REM is equivalent to 0.01 Sieverts. The relationship between REM and Sieverts stems from the fact that the REM (Roentgen Equivalent Man) is a traditional unit used to measure radiation dose, particularly in terms of its biological effect, while the Sievert is the SI unit for the same purpose. The conversion factor between these two units is established for practical purposes in radiation measurement and safety. Specifically, 1 REM translates to 0.01 Sv, meaning that a dose of 100 REM would be equal to 1 Sv. This conversion is crucial for professionals working in radiation safety and health physics, as it allows them to communicate and calculate doses effectively across different measurement systems. Understanding this relationship helps professionals apply protective measures effectively and ensures compliance with safety regulations.
